256 Chcetura Dominicana. 



and the upper coverts are much produced, so as to reach nearly 

 to the end of the rectrices." In Mr. Ober's example from 

 * Tobago, the upper coverts reach quite to the end of the tail- 

 feathers. 



The species from Dominica is very distinct, and I think is 

 undescribed. The Tobago bird is blacker above, and has the 

 abdomen also black ; it is at once distinguished by its light 

 ashy upper tail-coverts. 



The only other species requiring notice, if it really does, is 

 the Hirundo acuta, Gin., from Martinique, which does not 

 seem to be recognized by late writers, and is not noticed by 

 Mr. Sclater in his Notes of the Cypselidse. The locality given 

 for it, viz., Martinique, is what has induced me to allude to it. 



Gmelin's name is based upon the " Sharp-tailed Swallow " of 

 Latham, who gives the size as that of a wren, " length three 

 inches and eight lines ;'•' he cites Buffon and Brisson. It is 

 " L'Hirondelle noire acutipenne de la Martinique " of Buffon, 

 PI. Enl., 'No. 544. He describes it as being very small, the 

 size of a wren, the length 3 inches and 8 lines ; the whole 

 upper part of the body without exception black, etc., the wings 

 extending beyond the tail eight lines. Boddsert refers this to 

 H. pelasgia, Linn., but they dp not agree in size or color. 



It is "Hirundo Martinicana" of Brisson, who also gives its 

 size as that of a wren, and its length 3 inches 8 lines ; alar ex- 

 tent 8 inches ; wings extending 8 lines beyond the tail ; he 

 names all the upper parts as being black, among them the 

 uropygium. 



The Dominica bird differs strikingly from this, the length 

 being 4 7-8 inches ; alar extent, 10 1-2 inches ; the wings 

 extending two inches beyond the tail, and the rump being 

 ashy. 



' This Martinique species, if correctly described, remains yet 

 to be rediscovered.
