474 THE AGE OF MAMMALS 



Phasianinae belong to a group hitherto unrecorded in America. The present 

 range of the sub-family of peacocks is now limited to the Oriental region of 

 southern Asia, but fossil forms are recorded from the Miocene, Pliocene, 

 and Pleistocene of Europe, and from the Siwalik beds of India. The occur- 

 rence of this species {Pavo californicus) in America is therefore to be con-

sidered in connection with the Pliocene invasion (p. 337) of the Pacific 

 Coast by Asiatic antelopes. 



At Washtucna Lake, Franklin County, Washington^ (Fig- 194, 32), 

 there is a large proportion of forest aiid mountain types but there are no 

 aquatic mammals.^ Whether the animals found here are truly associated 

 in the same level is not known. In the same neighborhood are boggy 

 springs from which Elephas columbi and a species of Bison have been ob- 

 tained, a fact which adds to the suspicion that this is a mixed fauna. This 

 appears to belong to the latter part of the Equus-Mylodon-Camelops Zone, 

 and associated with these plains-living forms are remains of distinctively 

 forest types, including two species of moose (Alces) and of Virginia deer 

 (Odocoileus), as well as of a mountain sheep {Ovis montana). Among the 

 felids we find the puma {Felis concolor), and a larger leonine cat {F. impe- 

 rialis), as well as the lynx (F. canadensis).
