ADDITIONAL REMARKS, 923 
GerorniyPis TricHAs, Cab., p. 241.—A specimen from Fort Bridger has the light band 
margining the black of forehead posteriorly, extended over nearly the whole crown, and of a 
whiter shade than usual. This is scarcely indicative of a specific difference unless it should 
prove to be constant in western specimens, which does not appear to be the case,

and Fort Bridger. 
HELMINTHOPHAGA RUFICAPILLA, Baird, p. 256.—Yort Tejon. J. Xantus de Vesey. 
Denproica Townsenpi1, Baird, p. 269. Cantonment Burgwyn, N. M. Dr. W. W. Anderson. 
Denproica NIGRESCENS, Baird, p. 270.—According to Mr. Sclater, the Sylvia halseii of Giraud 
is the female of this species. Itis found at Oaxaca. Mr. de Vesey has collected itat Fort Tejon. 
Pyrane@a RusRA, Vieill., p. 300.—A curious variety of this species, shot near Niles, Michigan, 
probably a male, has been furnished for examination by Dr. Sager, of Ann Arbor. It has the 
wing and tail black, as usual; but all the rest of the plumage is saffron yellow, instead of olive 
green above and yellowish beneath, as in the young male generally. There isa slight resemblance 
to P. ludoviciana ; but the yellow is not pure Jemon color, but has an orange shade, and the 
yellowish bands of the wings and the red of head are wanting. 
Hrrunpo tuntrrons, Say, p. 309.—Mr. Sclater considers the H. melanogaster of Swainson 
(Petrochelidon swainsonii, Sclater) as quite distinct, and more allied to H. fulva. 
Proans, ———-——— ?—A Progne collected by Mr. Wiirdemann at Cape Florida, May 18, 
1858 (No, 10368), has the following characters : 
Tail deeply forked (depth .80 of an inch). First quill rather shorter than second. Bill 
very broad. Above glassy steel blue and purple, asin P. purpurea; under parts dark smoky 
brown, passing on the belly into dull whitish. Under coverts whitish at base, passing into 
mottled brown to the tip. Length, before skinning, 7.50; extent, 15; wing, 5.50. 
This skin differs from any specimens before me of P. purpurea in rather smaller size and the 
differently colored under plumage. The dark tail coverts separate it from P. dominicensis and 
chalybea. It may, after all, however, be nothing more than a peculiar stage of plumage of P. 
purpurea. 
AMPELIS GARRULUS, Linn. p. 317. Mr. Drexler saw ‘‘ millions’’ of this species while in the 
winter camp of the South Pass wagon road party, at the head of Powder river, Nebraska. Every 
tree for miles was filled with them, the flock rivalling that of the wild pigeon in its size, 
CiciLorsis NiTeNS, Bd. p. 320.—Mr. Sclater writes that the type of Cichlopsis (Turdus 
leucogonys of Berlin Museum) is very different from Ptilogonys nitens, Sw. He proposes for 
the latter the generic name of Phainopepla, Sclater. 
MYIADESTES TOWNSENDII, Cab., p. 321.—Mr. Sclater is decided as to the difference of JL. 
obscurus. 
CoLLyRIO BOREALIS, Baird, p. 324.—A male shrike in good spring plumage, collected at Fort 
Bridger, differs froma Pennsylvania specimen, killed in November, in rather larger size, clearer 
grey above, and nearly white upper tail coverts. 
HARPORHYNCHUS CRISSALIS, Henry, p. $51.—This name was erroneously printed in the 
Proceedings of the Philadelphia Academy as 7’. dorsalis. The page was afterwards cancelled 
and reprinted. 
A second specimen has been collected at Fort Yuma by Lieutenant Ives’s party. 
TROGLODYTES HYEMALIS, Vieill., p. 369.—Fort Tejon. J. Xantus de Vesey. 
CERTHIA MEXICANA, Gloger, p. 373.—Additional specimens from the west all show a much 
longer bill than eastern ones, tending to substantiate the existence of a second species.
