Mr. Wbitely's specimens are much smaller than the usual 

 size of this species, the wings measuring only 7*4 inches 

 instead of 8"1 inches. They may be referable to the bird 

 from Colombia recently described by Mr. Lawrence as 

 Hemiprocne minor, or in part at least to H. albicincta, Cab. 

 (J. f. Orn. 1862, p. 164). But are these small birds speci- 

 fically distinct ?
