Genus POOECETES Baird 



[Poocaetes gramineus] variety confinis Baird 



in Baird, Cassin, and Lawrence, Rep. Expl. and Surv. R.R. Pac. 9: 448, 

 1858. 

 =Pooecetes gramineus confinis (Baird). See Hellmayr, Catalogue of 



birds of the Americas 11: 513, 1938. 

 8945. Adult female. "Loup fork of Platte"=(as of July 29, 1857) the 

 confluence of the Dismal River with the Middle Loup, near Dunning, 

 Blaine County, Nebraska. July 29, 1857. Collected by Ferdinand V. 

 Hayden. Exploration of the Upper Missouri and Yellowstone. 

 8942. Immature male. Same data as No. 8945. 



Baird established this form upon a very long series of cotypes from many 

 parts of the West, but the restricted type locality "Loup fork of Platte" has 

 been generally accepted for many years. (I have been unable to learn when 

 and by whom the restriction was made.) In the circumstances, I accept here 

 as cotypes only Nos. 8942 and 8945, both taken at the same place on the 

 same day. (No. 8947, stated by Baird to have been collected on July 29, 

 1857, was, according to the museum register, in fact shot on July 19 and thus 

 came from some other reach of the stream; it cannot now be found in the 

 collection.) 



Warren's party, of which Hayden was a member, followed the Loup 

 Fork (=Middle Loup River) from mouth to source; birds taken anywhere 

 along its banks were labelled simply "Loup Fork." The map accompanying 

 Warren's "Preliminary Report of Explorations in Nebraska and Dakota in 

 the Years 1855-'56-'57," (1875), shows their camp sites with dates.
