~Cnemidophorus calidipes~ Duellman

_Cnemidophorus calidipes_ Duellman, Occ. Pap. Mus. Zool.
Univ. Michigan, 574:1, December 23, 1955.--Capirio,
Michoacan, Mexico.

Apatzingan (56); 12-20 km. S of Apatzingan (5); 19 km. E of
Apatzingan (5); 25 km. S of Arteaga; Capirio (57); El
Espinal (13); Jazmin (9); 11 km. S of Lombardia; Nueva
Italia.

This small, distinctive species of the _sexlineatus_-group of
_Cnemidophorus_ was discovered in the Tepalcatepec Valley in 1955
(Duellman, 1955); subsequent field studies showed it to be widespread in
the valley (Duellman, 1960c). One specimen (KU 29747) is from the
relatively arid, low Pacific slope of the Sierra de Coalcoman, 25
kilometers south of Arteaga. All other specimens have been taken at
elevations of 200 to 650 meters in the Tepalcatepec Valley, where the
species characteristically inhabits the open scrub forests of the valley
floor, especially the _Cercidium-Prosopis-Apoplanesia_ associations,
where there is a sparse growth of grasses. In this habitat it is most
frequently seen in association with _Cnemidophorus costatus zweifeli_
and _C. deppei infernalis_.

Aside from the characters given in Table 5, _Cnemidophorus calidipes_
differs from other species of _Cnemidophorus_ in Michoacan by possessing
a complete (or nearly so) supraorbital semicircle-series of granules; in
other species the granules seldom extend anteriorly beyond the posterior
border of the frontal.

~Cnemidophorus communis communis~ Cope

_Cnemidophorus communis_ Cope, Proc. Amer. Philos. Soc.,

restricted to Colima, Colima, Mexico, by Zweifel (1959a:74).

_Cnemidophorus communis communis_, Zweifel, Bull. Amer. Mus.
Nat. Hist., 117:74, April 27, 1959.

Aguililla (2); Apatzingan (6); 13 km. S of Arteaga (2); 19

The specimens from Coalcoman and the coastal localities were referred to
_Cnemidophorus sacki copei_ by Peters (1954:18) and Duellman (1954b:12).
Zweifel (1959a) referred these specimens to _Cnemidophorus communis
communis_ and pointed out the probable sympatry of _C. communis_ and _C.
costatus_ (= _sa
