1919] Merriam: Tertiary Mammalian Faunas of Mohave Desert 439 



EXISTING LIFE OF THE MOHAVE AREA 



The vegetation of the Mohave area is at the present time limited 

 to desert types, and the contrast with the flora on the opposite side 

 of the mountains bordering the desert to the west is marked. Plants 

 of arboreal types comprise only a very few junipers and the tree 

 yuccas. The creosote bush is commonly present and is the dominant 

 plant of this area. 



The Recent mammalian fauna of the desert includes thirty-five 

 species, of which twenty-one are rodents. The Ungulata include only 

 the pronghorn antelope (Antilocopra americana) and the desert big- 

 horn (Ovk nelsoni). The Carnivora include the desert coyote [Canis 

 ochropus cstor), the Mohave Desert kit fox (Vulpcs macrotis arsipus), 

 the California raccoon (Procyon lotor psora), a spotted skunk, a 

 striped skunk, the northwestern cougar (Felis oregonensis) , and the 

 desert wildcat (Lynx eremicus eremicus). The rodent fauna com- 

 prises thirteen genera which are included in the representative list 

 given below, kindly furnished for this study by Dr. Joseph Grinned.
