REPTILES OF THE TACIFIC COAST. 



15 



This area shares with the southern coast or San Diegan 

 Fauna alone only Hijpsiglena ochrorhy nchus , Salvadora 

 grahamuv, and probably Arizona elegant, and with the 

 valleys or Californian Fauna possibly Bascanion tcenia- 

 tum, while in common with both these areas it has Uta 

 stansburiana, RhinocheUus leeontei, Bascanion fiagellum 

 frenatum, Thamnophis hammondii, and perhaps Scelop- 

 orus biseriatus. Moreover, it lacks twenty -seven (or 

 thirty-three) species and subspecies which occur in one 

 or both of these adjoining Fauna}, and possesses none 

 of those found in the Sierra Nevada and northern coast 

 areas. The Desert Fauna is the most distinct of the 

 minor life areas of California. 



The San Diegan Fauna. — This area comprises the 

 western portions or coastal slopes of San Diego, River- 

 side, Orange, San Bernardino, and Los Angeles Coun- 

 ties, excepting the higher lands, which belong rather 

 with the Sierra Nevada. It is, in the main, a warmer 

 and dryer area than the Californian Fauna, to which it 

 is most closely allied. 



The reptiles of this Fauna are twenty-eight (or thirty) 

 in number, of which the following eight (or nine) are 

 peculiar to it: 



Uta mearusi, 

 Sceloporus orcutti, 

 Phrynosoma blainvillii, 

 Xantiisia heushawi, 

 Xantusia riversiaua * 



Cnemidopborus stejueuteri, 

 Verticaria hyperjthra beldingi, 

 Lichanura roseofiisca, t 

 Crotalus ruber. 



It shares with only the Desert Fauna Hypsiglena och- 

 rorhynchus, Salvadora graharaioi, and probably Arizona, 

 elegans; with the Californian Fauna, Anniella pulchra, 

 Lampropeltis californice, Bascanion laterale, and perhaps 



*In8\ilar. 



t Occurs also near Tucson, Ariz.
