224 BULLETIN UNITED STATES GEOLOGICAL SURVEY. [Yol.Yl. 



saw a few at Fort Mojave, and says it seems more of a sylvan species 

 than tristis^ sometimes feeding on the ground on grass-seeds as well as 

 on the buds of various plants and trees, but prefer the willows and cot- 

 tonwoods growing in wet places. In the Colorado Valley they fed upon 

 the seeds of Artemisia, sp. (?) 



Chrysomitris pinus (Wils.) Bp. — ^Pine Goldfinch. 



Occur during the summer in all the pine forests. They have the same 

 gregarious habits as C. tristis, though they rarely descend to the sur- 

 face vegetation, preferring the pines, feeding upon the seeds of various 

 coniferous trees, willows, &c. 



CentropJianes la/pponicus (Linn.) Caban. — ^Lapland Longspur. 



Mr. Eidgway recognized this species during the severe winter weather 

 among the large flocks of Horned Larks {Eremophila alpestris) around 

 Carson City. It is probable that during the cold weather they visit the 

 northern portions of I^evada, as their southern limit east of the Eocky 

 Mountains extends farther south during similar seasons. 



Passerculiis sandwichensis alaudinus (Bp.) Eidgw. — Western Savannah 



Sparrow. 



This variety has been found by nearly all observers throughout the 

 marshy districts of the northern and middle regions of the State, and 

 is one of the most abundant of the genus. 



This species is chiefly represented on the California coast by anthinus,* 

 and from the Columbia Eiver northward to Alaska by P. sandwichensis 

 savanna.] 



Pooecetes gramineus confinis Baird. — Western Grass Finch. 



Abundantly distributed over the j)lains in the upper portions of the 

 State, arriving at Carson City, according to Mr. Eidgway, in April. 

 They migrate southward during the autumn, and have been found a win- 

 ter resident in the Colorado Valley. 



Coturniculus passerinus perpallidus Eidgw. — ^Western Yellow-winged 



Sparrow. 



Generally distributed over the valley portions, as Mr. Eidgway found 

 it, though not near the marshes, like the Savanna Sparrow, but upon 

 the drier grassy plains. Was found to breed near Eureka. 



CJiondestes grammica strigata (Sw.) Eidgw. — Western Lark Finch. 



Common in favorable localities over nearly the whole of IsTevada. Dr. 

 Cooper did not find it in the Colorado Valley in the vicinity of Fort Mo- 

 jave, though it has been obtained at Fort Yuma. 



* Passerculiis anthinus, Bonap. — As above stated is found throughout the marshy areas 

 of the Pacific coast, has a slender bill, and is much more heavily marked below with 

 small dark and distinct spots. 



tP. sandwichensis savanna (Wils.), Eidgw. — This species was found on the Columbia 

 Eiver in spring and fall onlj^, during their migrations from the north and south. 

 Dr. Cooper thinks, therefore, that as they were absent from that locality from April to 

 October, they probably spent the winter in Southern Oregon and California.
