The essential characters of J. canicepa consist in the reddish bill, with slight black tip, tlio 

 well marked rufous confined strictly to the middle of the back, and not extending on the wing 

 coverts at all. The head and neck all round are grey or ash, this color extending on the sides, 

 leaving the middle of belly only white, as in the J. hi/cmali.s, from wliich the red back distin- 

 guishes it. It shares the red bill with liycmalis and oregonus, both J. cinereus and dorsalis 

 having the upper mandible black, the lower yellow.

Peucaea Ri'FiCEPS, Baird, p. 48G. — Fort Tcjon. J. Xantus de Yesey. 



Passerella schistacea, Baird, p. 490. — Eleven specimens from Fort Bridger, while generally 

 resembling those from Fort Tejon, differ in a much smaller bill, as in the type from the head 

 waters of Platte. Should this character be considered as specific, the bird of Fort Tejoa may 

 be called P. niegarhyncJius. 



QuiscALus BARiTUS, VieilL, p. 556. — This species was found to be very abundant on Indian 

 Key, Florida, by Mr. Wurdemann, in the spring of 1858.

Bonasa umbellus, var. xjmbelloides, p. 630. — Mr. Drexler collected a variety of the ruffed 

 grouse in the winter camp, in November, corresponding with what Douglas calls T. mnbelloides. 

 Its chief peculiarity lies in the bluish grey, which replaces the reddish yellow which jjrevails in 

 the common species. I am unable to distinguish any other features of importance indicative 

 of specific differences, although it may be that such exist. Douglas's specimens were obtained 

 in the valleys of the Rocky mountains, on the sources of the Pearl river, Linn. (Trans. XVI, 

 1833, 148.) 



GA^rBETTA melanoleuca, Bon., p. 731. — Among Mr. Drexler's specimens from Fort Bridger is 

 a skin which differs in having the legs of a more greenish tint than in eastern ones. The basal 

 web of the toes is greater. The entire rump is banded two, three, or four times on each feather. 

 The under part and sides are more conspicuously banded than in eastern birds. 



Trtngites rcfescexs, Cab., p. 739. — This species is not omitted by Bonaparte in his list pub- 

 lished in Comptes Eendus, as stated in page 739, but is given by him under Actiturus. 



Anser hyperboreus, p. 760. — From a recent examination of geese in the collection of the 

 Philadelphia Academy, in company with Mr. Cassin, I am now satisfied as to the correctness of 

 his separation of caeridescens as a distinct species, the young hyperhoreus being (juite different. 

 It is also very probable that A. albalus, his smaller snow goose, is distinct from hyperhoreus. 



Bernicla leucopareia, Cassin, p. 765. — The specimen in the Philadelphia Academy figured 

 by Mr. Cassin agrees very closely with Brandt's type in small size, pale breast, and black chin, 

 separating the white cheek patches into two. In some respects the specimen I describe resembles 

 A. iMrvipes, Cassin, as to feet and size, but differs in dark abdomen and white collar below the 

 black neck. 



Erismatura DOMINICA, p. 811. — According to Dr. Cabot, Proceedings Boston Soc. Nat. History^ 

 YI, August, 1858, 375, a full plumaged male was shot at Alberg Springs, Missisquoi bay, Lake 

 Champlain, on the 2fith of September, 1857, and is now in the cabinet of the Boston Society of 

 Natural History. The E. dominica is ferruginous above, the head black anteriorly, the specu- 

 lum white. Length 13^ inches.
