specimens from Utah, I can see no reason for not regarding 

 all these Utah and Nevada specimens as merely interme- 

 diate between the typical P. d. douglasin, of the north- 

 western coast, and typical P. d. hernandesi of Arizona, but, 

 since the majority of these specimens from Utah and 

 Nevada are not like either of those two subspecies, it seems 

 best to include them with the Painted Desert specimens as a 

 third subspecies, P. d. ornatissium. 



Specimens from Idaho also are intermediate. Those 

 from eastern Idaho are certainly identical with those from 

 Salt Lake City, Utah. My series from western Idaho is 

 too limited to enable me to be certain as to their characters. 

 These specimens and those from eastern Oregon and Wash- 

 ington seem increasingly like P. d. douglassn. Still, all 

 Idaho specimens I have seen have larger horns than are 

 present in the few specimens at hand from the far west. It 

 seems best, to me, to regard all the Idaho specimens as P. d. 

 ornatissimum y purely as a matter of convenience, remem- 

 bering that they are merely a series of geographic interme- 

 diates. 



Distribution. This subspecies in typical form, occurs in 

 Washington, Oregon, and extreme northern California. 



P. douglassn douglassn has been taken in Washington 

 near Fort Steilacoom, Spokane, Wallula, Fort Walla Walla 

 and North Yakima. 



In Oregon, it has been secured in the Willamette Valley, 

 between Portland and Salem 5 at Grants Pass, Josephine 

 County; in the Upper Klamath Valley and at Klamath 

 Lake, Klamath Falls, and Olene, Klamath County; in the 

 basaltic region between Warner and Goose lakes, between 

 Plush and Blue Creek, near Plush, and in the Chewaucan 

 Valley, Lake County; near Buck Creek, Crook County; 

 Voltage, Harney County; and on the Deschutes River.
