the playa. C. tesselatus is marginal in its existence at the type lo- 

 cality, being common to higher zones (and different edaphic conditions) 

 but not those as cool and mesic as favored by _C. exsanguis . _C. tessel- 

 atus occurs to the apparent complete exclusion of _C. tigris in an area 

 of yucca-grassland and Larrea -"grassland" about 10 miles north of the 

 type locality.

 species: Cnemidophorus exsanguis and Cnemidophorus sonorae (Sauria: 

 Teiidae). JOURNAL OF HERPETOLOGY 7(4): 379-380. 



Combined samples of_C. exsanguis from Bernalillo and Catron Coun- 

 ties, New Mexico, were compared to samples of C. sonorae from Cochise 

 County, Arizona. 6 proteins representing at least 9 gene loci were ex- 

 amined; the separate populations of the two forms differ in at least two 

 of them. No intraspecific variation was found.

 ards of the genus Cnemidophorus . PH.D. DISS., UNIV. OF NEW MEXICO.

Protein patterns are given for Cnemidophorus inornatus , _C. neomex - 

 icanus , _C. tesselatus , _C. tigris and _C. uniparens . Variations in pat- 

 terns are discussed. There are interpopulational differences in _C. tig - 

 ris marmoratus in New Mexico. The same kinds of differences exist in_C. 

 tesselatus; sibling species within this taxon are suggested. 25% of bi- 

 sexual gene loci examined are polymorphic whereas only 10% (6.6% if _C. 

 tesselatus is omitted) of unisexual gene loci are. _C. neomexicanus may 

 be a very young species. No variation was found in _C. tesselatus class 

 E lizards examined. It is suggested that variation in protein patterns 

 of C, inornatus and C. uniparens supports neutral selection, and that 

 the remainder of the data presented here equivocates between neutral and 

 natural selection (this entire work is poorly done in the opinion of the 

 author of this review).

 lizards: functional morphology and evolution. PAPEIS AVULSOS DE ZOOL- 

 OGIA SAO PAULO 27(15): 179-213. 



Several species of Cnemidophorus ( burti stictogrammus , inornatus , 

 neomexicanus, sexlineatus , tesselatus and tigris ) were used. Details of 

 skull morphology, tongue and hyoid musculature, and trunk and limb skel- 

 etons are given. New subfamilial arrangements are made. The Teiinae, 

 which includes the genus Cnemidophorus , are large in size and actively 

 escape from predators. They are inertial feeders specialized to rapidly 

 ingest relatively small prey.
