Sceloporus hiseriatiis and Lampropeltis hoylii; and with 

 both these Faunse, Uta stansburiana, Rhinochcilus lecontei, 

 Bascanion ffxigellum frenatum, Thamnophis hamviondii, 

 SLiid i>evhaps Scelojyor us biseriatiis. It lacks twenty -five 

 species and subspecies of the Desert Fauna, and eight 

 (or nine) of the Californian. 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 Californian. 



The Californian Fauna. — The Californian 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, CuemiJophoruis tigris uudulatus, 



Phrynosoina froutale, Tautilla eiseni. 



It shares with the Desert Fauna alone possibly Bas- 

 canion tceniatuni; with the Desert and San Diegan 

 Faunae, Uta stansburiana, Rhinocheilus lecontei, Bascanion 

 flagelluin frenatum, Thamnophis hammondii, and perhaps 

 Sceloporus biseriatus ; with the San Diegan Fauna alone, 

 Anniella pulchra, Lairipropeltis californicv, Bascanion 

 laterale, and perhaps Sceloporus biseriatus and Lampro- 

 peltis boylii; with the Pacific Fauna alone, Sceloporus 

 occidentalis ; with the Pacific and San Diegan Faunae, 

 Gleiwmys marmorata and Gerrhonotus scincicauda; and 

 with all except the Desert Fauna, Eumeces skiltonianus , 

 Diadophis amabilis, Bascanion constrictor vetustum, Tham-
