ADDITIONAL REMAUKS. 923 



fiKOTiiLYPis TKlciTAS, Cab., p. 2-11. — A specimen from Fort Bridgcr has tlie light band 

 margining the bhick of ibrclieail 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, 



HELMiNTHornAGA RUFICAPILIA, Baird, p. 256.— Fort Tejon. J. Xautus de Vesey. 



Dendroica TOWNSENDir, Baird, p. 269. Cantonment Burgwyn, N. M. Dr. W. W. Anderson. 



Dexdroica nigrescens, Baird, p. 270. — According to Mr. Sclater, the Sylvia haheii of Giraud 

 is the female of this species. It is found at Oaxaca. Mr. de Vesey has collected it at Fort Tejon. 



Pyraxo.a rubr.\, 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 is a slight resemblance 

 to P. huhviciana ; but the yellow is not pure lemon color, but has an orange shade, and the 

 yellowish bands of the wings and the red of head are wanting, 



HiRUNDO mNTFRONS, Say, p. 309. — Mr. Sclater considers the E. melanogaster of Swainson 

 {Petrochelidon sivainsonii, Sclater) as quite distinct, and more allied to H. fulva. 



Progne, ? — A Frogne collected by Mr. Wurdcmann 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, as in P. purpiirea ; 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. dominiceims and 

 chahjhea. It may, after all, however, be nothing more than a peculiar stage of plumage of P. 

 purpurea. 



Ampelis GARRULtJS, 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. 



CiCHLOPSis xiTEXS, Bd. p. 320. — Mr. Sclater writes that the type of Cicldopsis {Turdus 

 leucocjonys of Berlin Museum) is very different from Ptilogonys niiens, 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 31. 

 obseurus. 



CoLLYRio borealis, Baird, p. 324. — A male shrike in good spring plumage, collected at Fort 

 Bridger, differs from a Pennsylvania specimen, killed in November, in rather larger size, clearer 

 grey above, and nearly white upper tail coverts. 



Harporhyxcuus crissalts, Henry, p. 351. — This name was erroneously prin^ed in the 

 Proceedings of the Philadelphia Academy as T. 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. 



Cerihia 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.
