cies were down in all heavily grazed habitats except Sonoran desert- 

 scrub. Cnemidophorus exsanguis (= probably flagellicaudus ) and _C. velox 

 were totally extirpated in some cases and Cnemidophorus tigris numbers 

 drastically reduced due to the elimination of favorable microhabitats 

 and/or the reduction of food supplies.

 gerald. 1982. The comparative anatomy of lizard ovaries, with empha- 

 sis on the number of germinal beds. 3. HERPETOLOGY 16(3): 2^0-252. 



Specimens of Cnemidophorus velox from Colorado and C. inornatus , 

 _C. tesselatus , _C. tigris and _C. uniparens from New Mexico all possessed 

 2 germinal beds (GB) per ovary. These are compact and located on the 

 dorsal ovarian surface antero-posterior to each other. Each ovary of 

 the above species undergoes 1-3 ovulations (presumably per year) except 

 for _C. tigris , which ranges i-ii. Instantaneous fecundity (the number 

 of ovulations from both ovaries at one time) is inversely proportional 

 to rates of follicular atresia in preovulatory ovaries of lizard spe- 

 cies with 2 GB/ovary. Temperate species tend to have relatively higher 

 instantaneous fecundities than tropical species, which also tend to 

 have only 1 GB/ovary. All the species of Cnemidophorus examined, how- 

 ever, have relatively low instantaneous fecundities for their GB count 

 and latitudinal position. This would tend to substantiate the fact the 

 Teiidae are by and large a tropical family and that the genus Cnemido - 

 phorus has expanded into temperate regions, and also that reproductive 

 strategies may be evolutionarily stable, complex, and inert (this re- 

 viewer).

 density probability function to determine the home ranges of Uta stans - 

 buriana stansburiana and Cnemidophorus tigris tigris . HERPETOLOGICA 

 19: 105-115. 



Home ranges estimated for male, female, and juvenile _C. tigris in 

 Nevada are .18, .10 and .09 acres with the minimum polygon method and 

 .71, 1.28 and .54 acres with the density probability function. Factors 

 influencing the estimation of home ranges are discussed.

Individuals of Cnemidophorus inornatus and _C. tigris near Las 

 Cruces, New Mexico, were followed for their entire daily activity per- 

 iod. The former species spent more time behaviorally thermoregulating 

 and foraged more thoroughly over a smaller area than did the latter.
