Sceloporus biseriatus and LamprOpeltis boylii; and with 

 both these Faunae, Uta stansburiana, Rhinocheiius lecontei, 

 Bascanion flagellum frenatum, Thamnophis hammondii, 

 and perhaps Sceloporus biseriatus. It lacks twenty - five 

 species and subspecies of the Desert Fauna, and eight 

 (or nine) of the California!!. Some species are common 

 to it and to one or both of the northern areas Sierra 

 Nevadan and Pacific. The San Diegan Fauna is most 

 closely allied to the California!!. 



The Californian Fauna. The California!! Fauna in- 

 cludes the western slope of the Sierra Nevada below the 

 Sierra Nevadan Fauna, and extends thence westward to 

 the ocean, excepting the area along the coast which 

 constitutes the Pacific Fauna and that part of the San 

 Joaquin Valley which belongs to the Desert Fauna. It 

 appears to reach the coast in Ventura, Santa Barbara 

 and San Luis Obispo Counties. Twenty-six (or twenty- 

 nine) reptiles have been found within its limits. Of 

 these, four are peculiar to it, as follows: 



Crotaphytus silus, Cnemidophorus tigris undulatus, 



Phrynosoma frontale, Tantilla eiseni.

It shares with the Desert Fauna alone possibly Bas- 

 canion tceniatum; with the Desert and San Diegan 

 Faunae, Uta stansburiana, Rhinocheiius lecontei, Bascanion 

 flagellum frenatum, Thamnophis hammondii, and perhaps 

 Sceloporus biseriatus ; with the San Diegan Fauna alone, 

 Anniella pulchra, Lampropeltis California;, Bascanion 

 laterale, and perhaps Sceloporus biseriatus and Lampro- 

 peltis boylii; with the Pacific Fauna alone, Sceloporus 

 occidentalis ; with the Pacific and San Diegan Faunae, 

 Clemmys marmorata and Gerrkonotus scincicauda; and 

 with all except the Desert Fauna, Eumeces skiltonianus , 

 Diadophis amabilis, Bascanion constrictor vetustum, Tham-
