tfange. — This interior form of the pretiosa group was described 
from northeastern Nevada, Specimens referable to this subspecies 
are at hand from Prineville, Crook County, Oregon, and Butte Creek, 
Siskiyou County, California (Mus. Yert. Zool.) [the latter inter- 
mediate toward Dana p. pretiosa] . It has already been recorded from 
Pine Creek, near Alturas, Modoc County (Camp, 19175, p. 124; Grin- 
ned and Camp, 1917, p. 148). Cope (1889, p. 433) says that he 
obtained Dana temporaria pretiosa [= luteiventris] “the entire length 
of the valley of the Warner Lakes, but not at Fort Bidwell. ” Speci- 
mens from Pendleton, Umatilla County (Van Denburgh in Gilbert 
and Evermann, 1895, p. 207), and Island City, Union County, Oregon 
(Van Denburgh, 1912a, p. 159) probably belong here, as also speci-
