I place this species in the genus Thaumatias ; for if this 

 may not be actually its proper place, I know of no more ap- 

 propriate one. It evidently has very little to do with Hemi- 

 stilbon, as represented by H. ocai, which is very closely allied 

 to Amazilia, and which should probably be allowed to remain 

 in that genus. Seii. De Oca [1. c.) has described a Humming- 

 bird, which he saw in a collection in Mexico, as Thaumatias 

 lerdi ; and, judging from his figure and description, I believe 

 it to be the same as T. norrisi, Bourcier. It is unquestion- 

 ably a Thaumatias, and is distinguished from T. Candidas, to 

 which it seems most nearly allied, by the throat and sides 

 of the neck covered with metallic golden green feathers, 

 and abdomen and flanks pale rufous, which are the chief 

 specific characteristics of T. norrisi. In other respects it 

 resembles very closely T. Candidas.

Lesson described and figured this species as quoted above, 

 and stated that it came from Guiana, which was an error, 

 as it is not found in that country, but is a native of Southern 

 Brazil. It is one of the smallest members of the white- 

 throated group of this genus, and has the sides of the throat 

 and breast more covered with metallic green than is the case 

 with any of its relatives of the satne section. Indeed the 

 white is displayed in the shape of a narrow white line run-
