ments of two sets to illustrate the latter: First set, .98 X .68; .86 X 

 .63, .85 X -63, and .84 X -60 of an inch. Second set, .98 X -64, .92 

 X -59, .88 X -60 and .84 X -60. This bird was very common in 

 Southern Arizona in the winters of 1872 and '73. 



64. Eremophila alpestris (Boie). Shore Lark. 



Taken during the winter, and also seen occasionally during the 

 summer on the alkali plains south of the post. The latter may be- 

 long to the var. clirysolcema, a more southern race. 



65. Agelaius phosniceus (Viel.). Eedwing Blackbird. 



A very abundant summer visitor; some remain about the swamps 

 at Malheur Lake through the winter. 



66. Agelaius gubernator (Bon.). Crimson-shouldered 

 Blackbird. 



This is an abundant species, but less abundant than phceniceus. 

 The eggs of these two species present but little difference. As a 

 general thing, the eggs of this form are not marked so much, and a 

 few are unspotted. The tricolor I have not met with here. 



67. Xanthocephalus icterocephalus (Baird). Yellow- 

 headed Blackbird. 



A very common species, breeding abundantly amongst the tides in 

 Malheur Lake. None remain during the winter months. It does not 

 breed in the swamps near the post,- but confines itself strictly to the 

 lake shore, and I have seen none at any distance therefrom. 



68. Sturnella neglecta (Aud.). Western Lark. 



A very abundant summer visitor, breeding everywhere in the low- 

 lands* as well as in the highest "mountain meadows. About Camp 

 Harney, they raise two or three broods in a season. 



69. Icterus bullocki (Bonap.). Bullock's Oriole. 

 Common during the summer months. Arrives about -May 10, and 



leaves early in September. The eggs show great variations in size, 

 shape and colors. One set in my collection, perfectly wedge-shaped, 

 measures 1.02 X -60. At Fort Lapwai, Idaho, it is particularly 

 abundant, and I have seen as many as five occupied nests on a single 

 small birch tree. 



70. Scolecophagus cyanocephalus (Cab.). Brewer's 

 Blackbird. 



An exceedingly abundant summer resident, a few remaining dur- 

 ing mild winters. It breeds in various situations. On the ground 

 the nests are placed on the very edge of the creek banks, in sage- 

 bushes when close to water, and in serviceberry bushes on a hillside
