164 Dr. Coues on the Ornithology of a Prairie- Journey, 



Of Collyrio excuhitoroides I have one specimen. Vireo sivain- 

 soni is not uncommon in summer ; concerning its validity as a 

 species distinct from V. gilvus, see Professor Baird^s remarks in 

 his ' Birds of North /America/ under the title of this last-named 

 bird. Another Vireo, which is the most abundant in summer, I 

 refer, with some hesitation, to V. solitarius. My numerous spe- 

 cimens come nearer to that species than to any other with which 

 I am acquainted, I have not yet found V. atricapillus , but I 

 am close to the locality whence it was first procured by Dr. 

 Woodhouse, and I have no doubt of obtaining it in time. 



Oreoscoptes montanus is common. Hitherto I have not found 

 Mimus polyglottus ; and I have been much surprised at not dis- 

 covering a single Harporhynchus of any species. Salpinctus 

 ohsoletus is rather uncommon. 



Thryothorus bewicki is rare ; Cistothorus palustris and Troglo- 

 dytes parkmanni are common. Lophophanes wollweheri and L. 

 inornatus are abundant, the former especially so, and resident all 

 the year. A species of Psaltriparus, which I cannot positively 

 identify, but which is probably P. plumbeus, is very abundant, 

 and resident all the year. In fall it occurs in large companies 

 of fifty or more. The irides of some individuals are light yellow, 

 of others dark brown. A species of Polioptila, either melanura 

 ov plumb ea, is not rare. 



Eremophila cornuta is common. 



Carpodacus californicus and C. cassini are not rare, the first 

 indeed is common. C. frontalis, I think, is not found here. 

 Chrysomitris mexicana is a characteristic bird, being quite as 

 abundant as C. iristis is in the east. Numerous specimens of 

 another species, which with muck hesitation I am inclined to 

 identify with C. lawrencii, were procured late in the fall. If they 

 are really what I take them to be, they are in a plumage hitherto 

 unknown to me. Passerculus alaudinus and Pooecetes gramineus 

 are common, particularly the first. Chondestes grammica is very 

 abundant, and in the fall Zonotrichia gambeli is exceedingly nu- 

 merous. Of the last, a few winter here. Poospiza bilineata is 

 very common, and P. belli not rare. Spizella pallida is rather 

 uncommon, but I have besides certainly one \yide antea, p. 118], 

 and I think also a second, new species of this genus. However,
