CALIFORNIA FISH AND GAME 91 



near the Mexican line in eastern San Diego, or western Imperial 

 counties. 



Many readers will doubtless be surprised to learn that Grinnell 

 states that the Oregon bison without any doubt formerly occurred in 

 the northeastern corner of California, where it apparently traversed 

 the semidesert valleys of eastern Modoc and Lassen counties. 



Four varieties of bighorn, or mountain sheep, are ascribed to 

 California. The lava beds bighorn formerly ranged this region in 

 the extreme northeastern portion of the State, where it is now thought 

 to be extinct as the last individuals are said to have died in eastern 

 Siskiyou County in the winter of 1913. The Sierra Nevada bighorn 

 still occupies the higher portion of the southern Sierra from the 

 vicinity of Mammoth Pass, Mono County, south to the vicinity of 

 Olancha Peak, in Tulare County. Under this form, Grinnell notes 

 that ascriptions of the mountain goat to this region of the Sierra 

 Nevada are apparently erroneous and are now thought to have been 

 based on the presence of bighorns. This author states that the range 

 of the desert bighorn is in general the mountain ranges of the Mojave 

 Desert and Inyo regions, north to the lower slopes of the White 

 Mountains, Mono County, south to the Chocolate Mountains and west 

 to the San Bernardino and San Gabriel mountains. 



The fourth variety of mountain sheep treated in this Review is the 

 Lower California bighorn, which occupies the mountains bordering the 

 west side of the Colorado Desert from the Mexican line, northwest to 

 the lower northern slopes of the San Jacinto Mountains, in San 

 Gorgonio Pass. Considerable discussion has recently arisen regarding 

 the number of sheep of this subspecies now inhabitating the State. 

 Investigations by M. Hall McAllister, Edmund C. Jaeger and State 

 game wardens seem to agree in that there are between two and three 

 hundred of these animals now ranging in Riverside and San Diego 

 counties. 



Grinnell's account of mammalian species ends with the aquatic 

 mammals, of which he lists nine whales, four porpoises, the dolphin, 

 cowtish, killer, grampus and blackfish. 



The paper closes with a very complete index. — James 3Ioffitt,

THE PRONGHOEN ANTELOPE IN LOS ANGELES COUNTY 



This is a supplementary note to the account of the antelope of 

 Antelope Valley, Los Angeles Countj^ in the July, 1932, issue of 

 California Fish and Game (Vol. 18, p. 258). The antelope herd at 

 that time was composed of seven individuals — one male and six females. 



On December 3 of this year, 1933. I again found the herd in the 

 rolling low hills of Antelope Valley five miles north of Sandberg and 

 counted four individuals, all females. I followed the herd in my car 

 across country for two miles and got as close as one hundred and fifty 

 yards on several occasions by approaching slowly. At this distance 

 field glasses brought them into good view for study. ]\Iy partner tried 

 to attract them by waving a red bandana in the breeze on the end of 

 a stick, but though their curiosity was aroused to the extent of their 

 standing still to look, they would not come toward us. They could 

 probably see all they wanted to at one hundred and fifty yards.
