Chcetura poliura, Lawr. (nee Temm.), Proc. U. S. Nat. 

 Museum, p. 62. 



Male. Upper plumage smoky-black ; lores black : rump dark ash ; up- 

 per tail-coverts brownish-black, just edged with whitish ; tail glossy black, 

 the spines fine and projecting for nearly a quarter of an inch ; wings glossy 

 black ; throat dark grayish-ash ; breast and abdomen of a warm* smoky- 

 brown ; under tail-coverts brownish-black ; bill black ; feet yellowish-brown.

The female is similar to the male in plumage. 



Habitat, Dominica. 



Types in National Museum, Washington. 



Remarks. In my Catalogue of the Birds of Dominica 

 (Proc. U. S. Nat. Mus., 1878), I referred this species, provis- 

 ionally to C. poliura, Temm., being partly induced to do so be- 

 cause that species was noted from Tobago, comparatively a 

 not very distant point. I then stated that it agreed quite well 

 with the measurements given of that species by Mr. Sclater, 

 in his Notes of the Cypselidse (Proc. Zool. Soc, 1865, p. 593), 

 but that the wing was shorter. The measurement of 3 7-8 

 inches, given by me, was taken- from Mr. Ober's note, and is 

 clearly an error, as, in the four specimens sent, the wings of 

 each measure 4 1-2 inches. 



Quite lately I received a collection made in Tobago by Mr. 

 Ober, and found in it an example of C. brachyura, Jard., 

 which Mr. Sclater says, " Does not seem to be decidedly differ- 

 ent from G. poliura, Temm., although the tail is rather shorter
