+
+<p>The systematic status of the populations of lizards assignable to
+<i>Cnemidophorus sacki</i> in western M&eacute;xico (Sonora southward to
+Jalisco) has been reviewed in detail by Zweifel (1959, Bull. Amer.
+Mus. Nat. Hist, 117 (2):57-116), who stated that the use of the
+specific name <i>sacki</i> for the western populations rests upon a reasonable,
+but as yet unproved, assumption that intergradation occurs.
+Although Zweifel examined specimens of the nominal subspecies
+from the upper Balsas Basin, he did not study specimens from the
+intervening area&mdash;the Tepalcatepec Valley in Michoac&aacute;n.</p>
+
+<p>Field studies and the examination of large series of preserved
+specimens of <i>Cnemidophorus</i> from the <a name="Tepalcatepec"></a><a href="#Typo_Corr">Tepalcatepec</a> Valley show
+the presence of <i>Cnemidophorus sacki</i> in the region between the
+ranges of <i>C. sacki sacki</i> in the upper Balsas Basin and <i>C. sacki
+occidentalis</i> in Jalisco and southern Nayarit. Furthermore, the
+populations of <i>sacki</i> inhabiting the Tepalcatepec Valley have characters
+of scutellation and coloration that distinguish them from
+other described subspecies of <i>sacki</i>. In recognition of the important
+contributions to the systematics of the genus <i>Cnemidophorus</i> made
+by Dr. Richard G. Zweifel, I propose that the subspecies of <i>Cnemidophorus
+sacki</i> in the Tepalcatepec Valley be named as follows:</p>

+<p><i>Holotype.</i>&mdash;University of Michigan Museum of Zoology No. 119542, from
+Capirio, Michoac&aacute;n, M&eacute;xico (185 meters), an adult male, one of a series
+collected on June 13, 1958, by William E. Duellman, Jerome B. Tulecke, and
+John Wellman. Original number WED 12310.</p>
+
+<p><i>Paratopotypes.</i>&mdash;UMMZ Nos. 119536-119541 and 119543-119550.</p>
+
+<p><i>Diagnosis.</i>&mdash;A race of <i>Cnemidophorus sacki</i> characterized by large size
+(more than 130 mm. snout-vent length in males), approximately 106 dorsal
+granules around the midbody, about 41 femoral pores, and a dorsal color-pattern
+in adult males consisting of lateral and dorsolateral rows of spots,
+paravertebral rows fused with middorsal light green area at least anteriorly,
+and pink throat having a median light blue spot or transverse band.</p>
+
+<p><i>Description of Holotype.</i>&mdash;Snout-vent length, 128 mm.; tail length, 252
+mm.; tail/body ratio, 1.97; scutellation typical of <i>sacki</i>&mdash;four supraoculars,
+enlarged postantebrachials, and enlarged mesoptychials; 107 granules around
+midbody (excluding enlarged ventrals); 45 femoral pores; three enlarged
+preanal scales; supraorbital semicircle-series extending anteriorly to posterior

+<div class="blkquote">
+<p>Top of head and nape dusty brown; tip of rostral and lateral edges of
+superciliaries dark cream-color; upper labials and sides of head anterior to
+eyes cream-color, mottled with blue; lower labials and postocular region pale
+blue; mental, postmental, and sublabials cream-color. Upper surfaces of
+forelimbs dull bluish gray, spotted with pale greenish yellow; dorsal surfaces
+of proximal one-fourth of tail light brownish gray turning to pale orange-brown
+posteriorly; lateral surfaces of tail bluish gray anteriorly and creamy brown
+posteriorly. Nuchal region light bluish gray; flanks dark gray; dorsal ground-color
+dark brown, somewhat paler posteriorly. Body having a row of cream-colored
+spots in place of a lateral stripe, and another row in place of dorsolateral
+stripe; dorsally, large diffuse tan or light green spots partially fused and
+tending to form irregular transverse markings. Chin to posterior end of sublabials
+pale pink, bordered posteriorly by bluish white area, and then pink.
+Mesoptychials, under surfaces of hind limbs, and belly cream-colored; anterior
+edges of belly scales dark blue; lateral two rows of ventrals on posterior two-thirds
+of body dark blue having light blue or cream-colored spots. Under
+surfaces of forelimbs bluish cream; ventral surface of tail cream-colored.</p>
+
+<p><i>Variation in Size and Scutellation.</i>&mdash;The largest male has a snout-vent
+length of 132 mm., the largest female, 114 mm., and the smallest juvenile, 34
+mm. The number of dorsal granules at the midbody varies from 91 to 117
+(106.2 ± 0.43); the ratio of the number of granules between the paravertebral
+stripes to the number of granules around the body (PV/GAB) varies from
+0.064 to 0.157 (0.097 ±0.007); the number of femoral pores varies from
+32 to 49 (41.1 ± 0.20). Usually there are only three enlarged preanals, but
+18 specimens have a somewhat enlarged scale anterior to the normal complement
+of three. In 15 specimens the supraorbital semicircle-series terminate
+short of the posterior edge of the frontal; in the others the series reach the
+frontal.</p>
+
+<p><i>Variation in Coloration.</i>&mdash;The coloration of juveniles and subadults varies
+little; large adults vary considerably especially in the amount of diffusion of
+the light green middorsal area. In some individuals the vertebral pale area
+does not include the paravertebral spots; in other individuals the pale area
+includes not only the paravertebral rows, but, at least anteriorly, the dorsolateral
+rows. In large males of about equal size (and collected at the same
+time) there is considerable variation in the amount of blue on the belly. In
+a few of the males the belly is white with only the anterior edge of each scale
+blue; in some only the lateral rows of ventrals on the posterior two-thirds of
+the body are blue; in others all of the posterior two-thirds of the belly is blue.</p>
+</div>
+
+<p><i>Ontogenetic Change in Color Pattern.</i>&mdash;The metamorphosis of
+color pattern in <i>Cnemidophorus sacki zweifeli</i> results in the dorsal
+ground-color becoming paler with age, the replacement of the
+stripes by spots, and finally in large males the suffusion of these
+spots.</p>
+
+<p>A single hatchling (UMMZ 114732) is available; this specimen
+has a prominent umbilical scar and a snout-vent length of 34 mm.
+The top of the head is olive brown; the dorsal surfaces of the limbs
+are dark brown with cream mottling; the dorsal ground-color is
+brownish black; this is paler on the lower flanks. The lateral and
+dorsolateral stripes are cream-colored; the paravertebral stripes are
+<span class='pagenum'><a name="Page_592" id="Page_592">[592]</a></span>
+white. There is a faint, diffuse vertebral stripe anteriorly (<a href="#Fig2">Fig. 2 A</a>).
+The throat and undersides of the limbs and tail are cream-colored;
+the belly is bluish white. In life the stripes were pale yellowish
+green, and the tip of the tail was pink.</p>
+
+<p>In larger individuals the dorsal <a name="ground-color"></a><a href="#Typo_Corr">ground-color</a> is dark brown; the
+lower flanks are grayish tan. Light brown diffuse spots are present
+in the lateral and dorsolateral dark fields. The tan vertebral stripe
+is diffuse and nearly fills the paravertebral dark fields; the paravertebral
+stripes are faint posteriorly; throughout their length they are
+scalloped&mdash;the beginning of their fragmentation into spots (<a href="#Fig2">Fig.
+2 B</a>).</p>
+
+<p>In subadults (± 80 mm. snout-vent length) the paravertebral
+stripes are fragmented into spots posteriorly. Also, the dorsolateral
+stripes in some individuals are fragmented posteriorly. The dorsolateral
+dark fields are somewhat paler than the lateral dark fields.
+Cream-colored spots are present on the flanks. The mottling on
+the thighs tends towards the formation of light spots (<a href="#Fig2">Fig. 2 C</a>).</p>
+
+<p>In small adults (± 100 mm. snout-vent length) the paravertebral
+stripes are entirely fragmented into spots. The lateral and dorsolateral
+stripes are broken into spots posteriorly. The middorsal pale
+area (formed by the suffusion of the vertebral stripe) and paravertebral
+and dorsolateral rows of spots are pale green. The cream-colored
+spots on the flanks are expanded to form vertical bars
+(<a href="#Fig2">Fig. 2 D</a>).</p>
+
+<p>Large adult males (± 120 mm. snout-vent length) have all of
+the stripes fragmented into spots. The diffuse middorsal area is
+expanded and encloses the paravertebral rows of spots. The pale
+spots present in the dark fields in smaller individuals are either
+absent or fused with spots resulting from the fragmentation of the
+stripes (<a href="#Fig2">Fig. 2 E</a>).</p>
+
+<p><i>Sexual dimorphism.</i>&mdash;Males attain a larger size (known maximum
+snout-vent length of 132 mm., as compared with 114 mm. in females).
+Males have larger but not more numerous, femoral pores,
+blue bellies, and pink and blue throats, whereas females are unicolor
+creamy white ventrally. The more nearly complete metamorphosis
+of color pattern exhibited by adult males probably is
+correlated with their large adult size. Large females retain complete
+lateral and dorsolateral stripes. The jowls of breeding males
+are swollen.</p>

+<p><i>Geographic variation.</i>&mdash;No noticeable geographic variation in
+this subspecies is evident in the series from the Tepalcatepec
+Valley. However, lizards from eastern Michoac&aacute;n (Chinapa, 6
+km. N of Tafetan, 6 km. S of Tzitzio, and 19 km. S of Tzitzio) differ
+slightly from those from the Tepalcatepec Valley; the eastern
+specimens have fewer dorsal granules and femoral pores, and a
+higher ratio of dorsal granules between the paravertebral stripes
+to the number of granules around the body (see Tables 1-3). No
+large adult males are present in the eastern series; the subadults
+and small adult males have color patterns like lizards of similar
+size from the Tepalcatepec Valley. The largest male from the east
+has a snout-vent length of 110 mm., rows of pale spots, and no trace
+of brown and tan cross-bars. Specimens of <i>Cnemidophorus sacki
+sacki</i> of equal size from Guerrero, Morelos, and Puebla in the upper
+Balsas Basin have a tan dorsum with dark brown cross-bars. The
+localities in eastern Michoac&aacute;n are intermediate geographically
+between the Tepalcatepec Valley and the known range of the
+nominal subspecies in the upper Balsas Basin. In characters of
+scutellation specimens from the east are intermediate between <i>C.
+sacki sacki</i> and <i>C. sacki zweifeli</i> in the Tepalcatepec Valley. However,
+in coloration the lizards from the east are like those from the
+Tepalcatepec Valley, but differ distinctly from the nominal subspecies.
+Therefore, the eastern series is referred to the subspecies
+<i>C. sacki zweifeli</i>.</p>
+
+<p><i>Comparisons.</i>&mdash;Four other species of <i>Cnemidophorus</i> occur in
+the Tepalcatepec Valley with <i>Cnemidophorus sacki zweifeli</i>. Of
+these, <i>C. calidipes</i> has a maximum snout-vent length of 79 mm., 66
+to 86 dorsal granules, and a light brown dorsum with pale blue
+spots and vertical bars; <i>C. communis communis</i> has a maximum
+snout-vent length of 135 mm., 105 to 144 dorsal granules, and a
+greenish tan dorsum with yellow spots; <i>C. deppei infernalis</i> has a
+maximum snout-vent length of 84 mm., 91 to 120 dorsal granules,
+and a striped pattern throughout life; and <i>C. lineatissimus exoristus</i>
+has a maximum snout-vent length of 98 mm., 108 to 135 dorsal
+granules, and a middorsal yellow stripe and vertical bars on the
+flanks. Both <i>calidipes</i> and <i>communis</i> are like <i>sacki</i> in possessing
+four enlarged supraoculars and enlarged postantebrachials, whereas
+<i>deppei</i> and <i>lineatissimus</i> have three enlarged supraoculars and
+granular postantebrachials. Juveniles of <i>calidipes</i> and <i>sacki</i> are
+alike in coloration but different in the extent of the supraorbital
+semicircle-series. In <i>calidipes</i> the supraorbital semicircle-series usually
+are complete, whereas in <i>sacki</i> the series never extended anterior
+to the posterior edge of the frontal.</p>

+
+<p>From the geographically adjacent populations of <i>sacki</i> (<i>sacki</i> and
+<i>occidentalis</i>), <i>zweifeli</i> differs in coloration and scutellation (see
+Tables I-III). <i>Cnemidophorus sacki sacki</i> has a dorsal pattern in
+adult males of dark brown cross-bars on a tan ground-color. Both
+<i>occidentalis</i> and <i>zweifeli</i> have variable, diffuse color patterns in
+large adults, but <i>zweifeli</i> differs from <i>occidentalis</i> in having a blue
+spot on the pink throat.</p>
+
+<p><i>Ecology.</i>&mdash;In the arid Tepalcatepec Valley <i>Cnemidophorus sacki
+zweifeli</i> lives at elevations of 160 to 1300 meters. In the lower parts
+of the valley the lizards live primarily in open scrub forests, characterized
+by deciduous trees offering only partial shade from the
+sun, especially during the prolonged dry season. Common trees in
+this scrub forest are <i>Acacia cymbispina</i>, <i>Cercidium plurifoliolatum</i>,
+<i>Mimosa distachya</i>, and <i>Prosopis juliflora</i>.</p>
+
+<p>During the dry season (November through May) adult males
+apparently aestivate; several large series collected in the winter
+include only subadults and females. This absence of males is
+corroborated by personal observations in the Tepalcatepec Valley
+in April and May. In the summer rainy season the lizards are active
+in the morning and again in the late afternoon; only <i>Cnemidophorus
+calidipes</i> is active during the heat of the midday. In some
+<span class='pagenum'><a name="Page_597" id="Page_597">[597]</a></span>
+areas of the scrub forest <i>Cnemidophorus sacki zweifeli</i> is found in
+association with <i>Cnemidophorus communis communis</i>. Throughout
+the scrub forest <i>C. sacki zweifeli</i> occurs with <i>C. deppei infernalis</i>.
+In some of the more dense scrub forest, where <i>C. sacki zweifeli</i>
+is not so abundant as in the more open forest, it has been taken
+with <i>C. lineatissimus exoristus</i>. In the open <i>Acacia-Cercidium</i> associations
+on the valley floor <i>C. sacki zweifeli</i> occurs with <i>C. calidipes</i>.</p>
+
+<p>This subspecies is not restricted to the scrub forest. On the
+lower slopes of the Cordillera Volcanica in Michoac&aacute;n <i>C. sacki
+zweifeli</i> has been collected in open pine-oak forest near Zirimicuaro
+and Ziracuaretiro.</p>
+
+<p><i>Distribution.</i>&mdash;<i>Cnemidophorus sacki zweifeli</i> inhabits the valley
+of the R&iacute;o Tepalcatepec in Michoac&aacute;n and probably extreme southwestern
+Jalisco, and the western part of the Balsas Basin in
+Michoac&aacute;n. No specimens have been seen from extreme western
+Guerrero, but <i>C. s. zweifeli</i> may occur there.</p>

+works. See paragraph 1.E below.
+
+1.C. The Project Gutenberg Literary Archive Foundation ("the Foundation"
+or PGLAF), owns a compilation copyright in the collection of Project
+Gutenberg-tm electronic works. Nearly all the individual works in the
+collection are in the public domain in the United States. If an
+individual work is in the public domain in the United States and you are
+located in the United States, we do not claim a right to prevent you from
+copying, distributing, performing, displaying or creating derivative
+works based on the work as long as all references to Project Gutenberg
+are removed. Of course, we hope that you will support the Project
+Gutenberg-tm mission of promoting free access to electronic works by
+freely sharing Project Gutenberg-tm works in compliance with the terms of
+this agreement for keeping the Project Gutenberg-tm name associated with
+the work. You can easily comply with the terms of this agreement by
+keeping this work in the same format with its attached full Project
+Gutenberg-tm License when you share it without charge with others.
+
+1.D. The copyright laws of the place where you are located also govern
+what you can do with this work. Copyright laws in most countries are in
+a constant state of change. If you are outside the United States, check
+the laws of your country in addition to the terms of this agreement
+before downloading, copying, displaying, performing, distributing or
+creating derivative works based on this work or any other Project
+Gutenberg-tm work. The Foundation makes no representations concerning
+the copyright status of any work in any country outside the United
+States.

+Gutenberg" is associated) is accessed, displayed, performed, viewed,
+copied or distributed:
+

+
+1.E.2. If an individual Project Gutenberg-tm electronic work is derived
+from the public domain (does not contain a notice indicating that it is
+posted with permission of the copyright holder), the work can be copied

+or charges. If you are redistributing or providing access to a work
+with the phrase "Project Gutenberg" associated with or appearing on the
+work, you must comply either with the requirements of paragraphs 1.E.1

+request, of the work in its original "Plain Vanilla ASCII" or other
+form. Any alternate format must include the full Project Gutenberg-tm
+License as specified in paragraph 1.E.1.

+1.F.1. Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection. Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.
+
+1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all
+liability to you for damages, costs and expenses, including legal
+fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
+LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
+PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE

+opportunities to fix the problem.
+

+that arise directly or indirectly from any of the following which you do
+or cause to occur: (a) distribution of this or any Project Gutenberg-tm
+work, (b) alteration, modification, or additions or deletions to any
+Project Gutenberg-tm work, and (c) any Defect you cause.
+
+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.

+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit http://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.
+To donate, please visit: http://pglaf.org/donate
+
+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+
+Most people start at our Web site which has the main PG search facility:
+
+ http://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
