RUFF-NECKED II rMMlXCJ-BlUD. 343 



copper-coloured gloss: the quills brownish purple, 

 and the tail dark blue. Viellot's specimen was 

 brought from Porto-Rico. Buffon describes his 

 Orvert as measuring only two inches in length, 

 and as having the belly white, and Mr. Latham 

 mentions a specimen of similar size and appear- 

 ance. It is therefore doubtful whether the Orvert 

 of BufFon be the same with this ; and a similar 

 doubt must remain with respect to the T. melllsugus 

 of Linnaeus. Monsr. Viellot however adds to the 

 description of his Oiseau-Mouche a gorge verte 

 that the young birds have the lower part of the 

 abdomen white. The Oiseau-Mouche tout-vert of 

 Monsr. Viellot seems to be no other than the 

 species above-described, differing only in being 

 more uniformly gold-green, or with less appear- 

 ance of the blue gloss.

THE Ruff-necked Humming-Bird is of a rather 

 smaller size than the Red-Throated, to which it is 

 in some degree allied, and, like that species, is
