REJ'TILES OF THE PACIFIC COAST. 17 



nojjhis parietalis, Crotalus lucifer, and perhaps Lampro- 

 peitU zonata and Lciinpropeltis hoylii. It lacks twenty- 

 five (or twenty-seven) reptiles of the Desert Fauna, 

 eleven (or twelve) of the San Diegan, two (or three) of 

 the Pacific, and three (or five) of the Sierra Nevadan. 

 The Californian Fauna is most closely allied to the San 

 Diegan. 



The Pacific Fauna. — The Pacific Fauna occupies a 

 narrow strip along the coast as far south as Monterey 

 County.* In the northern part of the State it widens 

 and merges with the Sierra Nevadan, to which it is 

 closely allied, but farther south it is confined to the 

 western slope of the outer Coast Range. It is inhabited 

 by fifteen (or seventeen) kinds of reptiles. Of these, 

 Gerrhonotiis burneitii and Anniella nigra are peculiar. 

 Sceloporiis occidentalis and Contia niitis it shares with the 

 Ca'ifornian Fauna only. Lampropeltis zonata is perhaps 

 confined to this and the Sierra Nevadan Faunae. Its 

 other species are wide-ranging. It lacks thirteen (or 

 sixteen) reptiles of the Californian Fauna, and four (or 

 five) of the Sierra Nevadan. This Fauna is much bet- 

 ter characterized by its batrachians, birds, and other 

 animals than by its reptiles. 



The Sierra Xevadan Fauna. — The fifth life area of Cal- 

 ifornia occupies a belt along the western (and eastern 

 also ?) side of the Sierra Nevada. One at least of its 

 reptiles reappears in the mountains of San Diego and 

 Riverside Counties. Twelve (or fourteen) kinds of rep- 

 tiles have been taken in this area. Gerrhonotus palmeri 

 and Eumeces gilherii are peculiar to it. Sceloporus grac- 

 iosus occurs here but in no other part of California ex- 

 cept the mountains of the southern part of the State. 



* Probably to Santa Barbara in mountains.
