120 3. IGUANID& 



During the breeding season some females have the under 

 surfaces and sides of the tail and body suffused with deep 

 salmon or salmon-red. This color disappears in alcohol. 



The following color description is of a specimen from 

 Magdalena Island, Lower California: 



The general ground color is pale hair brown, changing 

 to broccoli brown centrally, finely dotted with white and 

 cream-buff, and with small spots of very dark sepia which 

 increase slightly in size medially and posteriorly. There 

 are two faint, pale clay-colored cross-bars on the back above 

 the hind limbs, and several similar ones on the basal portion 

 of the tail. Between these bars are pairs of rather large 

 dark sepia spots, each with a small cream-colored center. 

 The tail has brown rings separated by narrower pale cream- 

 colored ones. The chest and belly are whitish, more or 

 less fleckled with slate. The throat has longitudinal olive- 

 gray bands and blotches on a pale cream-colored ground. 



Remarks. Mr. Camp has called attention to the fact 

 that specimens from the northern part of the range of this 

 species average fewer pores and shorter tails than those from 

 southern California. In our specimens the pores are as 

 shown in the following table:
