summer. I have seen a few of these birds near the summit of the 

 Canyon City mountains in June, 1876, where they undoubtedly 

 breed. It is a very familiar species, a number keeping constantly 

 about the houses in the post during the winter, many appropriating 

 the old nests of cliff swallows for roosting plaees. 



53. Poospiza belli var. nevadensis (Ridg.). Artemisia 

 Sparrow. 



A not very abundant summer resident, breeding on the sage plains 

 south of the post. None remain through the winter. 



54. Spizella monticola (Baird). Tree Sparrow. 

 Moderately abundant during the winter months, feeding amongst 



the shrubbery on the creek bottom, near the post. 



55. Spizella breweri (Cassin). Brewer's Sparrow. 



A common summer resident. Breeds abundantly amongst the 

 sagebrush covered plains in the vicinity of water. Their eggs show a 

 great deal of variation in shape and size, as well as in their mark- 

 ings. Some are but slightly pointed at the smaller end, others 

 pyriform, and others again of an elongated oval. Ground color a 

 pale bluish green, spotted irregularly, principally about the larger 

 end, so as to form a ring in many cases. Size- of eggs from different 

 nests, .70 X -50, .68 X -48, .63 X -49, .60 X .46, .59 X -46. 



56. Melospiza melodia var. fallax ? 



The race found here, a resident (partly, at least) throughout the 

 year, is, according to Mr. Lawrence, referable to fallax. 1 It is found 

 among the willows on the creeks, where it also constructs its nest. 



57. Melospiza melodia var. rufina (Baird). Rusty Song 

 Sparrow. 



In December, 1875, I took two specimens belonging to this race. 

 They are much darker than specimens of the former, but are per- 

 haps the true var. guttata. 



58. Melospiza lincolni (Baird). Lincoln's Finch. 

 Noticed in the spring of 1876, in considerable numbers on their way 



north, amongst the willows on Rattlesnake Creek, associated with a 

 number of Gambel's finches and Slate-colored sparrows. A few 

 remain to breed. 2 



1 Mr. Ridgway regards it as approaching guttata. Its eggs resemble those of 

 fallax. 



2 Peuccea ruficeps Baird is not included in this list for the reason that no speci- 

 men has been taken. An unidentified nest with eggs has been conjecturally re- 

 ferred to this species, but thus far without positive proof, and no specimen of the 

 bird has been obtained.
