I place this speeies 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. Sen. De Oca (/. 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 he the same as T. norrisi, Bourcier. It is unquestion¬ 
ably a Thaumatias, and is distinguished from T. candidus, to 
which it seems most nearly allied, by the throat and sides 
of the neek 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. candidus.

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 same section. Indeed the 
white is displayed in the shape of a narrow white line run-
