ADDITIONAL REMARKS. 925 



The essential characters of J. caniceps consist in the reddish bill, with slight black tij), the 

 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 ashj this color extending on the sides, 

 leaving the middle of belly only white, as in the J. liyemalis, from which the red back distin- 

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

 having the upjjer mandible black, the lower yellow.

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 Tejon may 

 be called P. megarhynchus.

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

BoNASA UMBELLUS, var. UMBELLOiDES, p. 630. — Mr. Drexler collected a variety of the ruffed 

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

 Its chief peculiarity lies in the bluish grey, which replaces the reddish yellow which prevails 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 Eocky mountains, on the sources of the Pearl river, Linn. (Trans. XVI, 

 1833, 148.) 



Gambetta 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. 



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

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



Anser hypereoreus, 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 caerulescens as a distinct species, the young hyperboreus being quite different. 

 It is also very probable that A. albatus, his smaller snow goose, is distinct from hijperboreus. 



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, parvipes, 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, 

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

 Champlain, on the 26th 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 IS^ inches.
