90 CALIFORNIA FISH AND GAME 



this (leer occurs south at least into the Yosemite reg:ion. The southern 

 black-tailed deer occupies the coast ranges from tlie south side of San 

 Francisco Bar, south throns'h IMonterev and San Benito counties into 

 northwestern San Luis Obispo County. 



Four subspecies of mule deer are ascribed to Califoi-uia. The 

 Rocky Mountain mule deer CJi'innell properly ascribes to the north- 

 eastern corner of the State, but we think that his statement that this 

 deer's range continues south through the main Sierra Neveda to Tuol- 

 umne Country will not be borne out wliou more evidence is secured. 

 According to our observations, the typical liocky Mountain mule ilecr 

 is a rather rare animal south of the vicinity of Truckee. South of that 

 point, a few bucks appear to migrate each spring from Nevada west- 

 ward toward the summits of the Sierra Nevada, and in the fall again 

 return to the eastern deserts to wdnter. 



The Inyo mule deer (see California Fish and Game, Vol. 19, 

 1933, p. 274) occupies the eastern slope of the southern Sierra Nevada 

 in Inyo and probably Mono counties. 



Grinnell states that the range of a third subspecies, the California 

 mule deer, extends w^est from the western margins of the Colorado 

 and Mojave deserts, northwest from the Mexican line in San Diego 

 County, through Santa Barbara County into San Luis Obispo County. 

 and northeasterly from Ventura County througli the Tehachapi and 

 Piute mountains at least to the vicinity of Walker Pass. He states 

 that this race probably occurs north along the western flank of the 

 southern Sierra Nevada, and we feel quite certain that it is this sub- 

 species that occurs northward in this region into the Yosemite region, 

 in which region this deer seems to interbreed with the Columbian 

 black-tailed deer, and probably even considerably further northward. 



Reference to page 81 in this issue of California Fish and Game 

 will indicate that another subspecies of mule deer has been named from 

 California and this new deer, the San Diego mule deer, occupies part 

 of the southern range ascribed to the California mule deer above. 



The burro deer is another subspecies of mule deer which Grinnoll 

 states occujiies the Colorado desert region, north along the Colorado 

 River, through the Chocolate and Chuckawalla mountains to the 

 Granite Mountains, and, formerly at least, from the Mexican line south 

 of Salton Sea through the Imperial Valley into central Riverside 

 County. 



Grinnell ascribes the western white-tailed deer to California on the 

 basis of a very definite record of a buck taken in January, 1922. on 

 Observation Peak, in eastern Lassen County. He also lists another. ])ut 

 not quite satisfactory, record for this deer from Toi)az, ^Mono County, 

 in 1930 (see ]\IcLean. California Fisn and Game, Vol. 17, 1931, 

 p. 342). 



T''"nder the range of the ])roiig-horn antelope, Grinnell advises 

 that this species apparently occui'rcd nearly throughout the State 

 south and east of the humid coast belt and below the main timber line. 

 Considerable numbers of antelope still exist in several separate bands 

 in Modoc. Siskiyou and eastern Lasseu counties. A small herd still 

 occupies the western side of the San Joaquin Valley, four individuals 

 are known to yet exist in Antelope Valley. Los Angeles County (see 

 page 91, this issue), a small herd is said to exist in northwestern 

 Snu Bernardino Countv. and a few individuals on the Colorado Desert
