Colorado Spring, Colorado (specimens in Mus. Vert, Zool.) ; Greeley, 
Colorado (Ellis and Henderson, 1913, p. 52) ; Green River and Big 
Horn Basin, Wyoming (Cary, 1917, pp. 19, 27) ; Camp Thorne [near

(Cope, 1883, p. 14; Coues, 1875, p. 630) ; and on the Painted Desert 
of Arizona (Stejneger, 1890, p. 117). Cope (1887, p. 12; 1889, p. 
306) records “a slightly differentiated variety” from Chihuahua and 
from Guanajuato, Mexico. Schmidt (1922, p. 633) lists one specimen 
from Ensenada, northern Lower California. According to Stecker 
(1915, p. 54), Cope records 8. hammondii from Helotes, Texas. The 
western localities of record are Wallula, Walla Walla County, Wash- 
ington, and Prineville, Crook County, Oregon (specimens in Mus. 
Vert. Zook), and the California stations given below.
