Gould’s description of this species was based upon specimens from Colombia, where 
this bird is not common, but is occasionally represented in the trade collections sent 
from Bogota. It is apparently absent from the low-lying lands of the Isthmus of 
Panama, but occurs in the more mountainous parts of that State and thence north- 
wards into Costa Rica, where its range terminates. In Ecuador its place is taken by 
H. jamesoni, an allied but distinct species. 
Hardly any difference can be traced between Colombian and more northern speci- 
mens, but the former have, as a rule, rather more bronze colour on the central rectrices; 
but this of itself is a variable feature, being absent altogether in some specimens and 
just visible in others, so that it is not available as a differential character. 
H. henryi was described by Mr. Lawrence from a young male specimen from yi uiz in 
Costa Rica 11, in which the bright spot on the throat and the bright crown had not 
been developed. The receipt of fully adult birds from Costa Rica has proved that 
H. henryi is a synonym of H. jacula.

FLORISUGA.

Florisuga stands as a rather isolated genus in the Trochilide, having no near allies. 
It comes, perhaps, next to Lafresnaya. As in Heliodowa, the nasal covers are feathered, 
but the bill is much more slender and decidedly curved ; the tail is barely forked. 
This latter character, its normal instead of lengthened under tail-coverts, and the 
rounded ends to the rectrices separate it from Lafresnaya. 
The range of the genus extends over a large portion of Tropical South America, one 
species occupying the lowlands from Southern Mexico to the Amazons Valley, a second 
species being found in South-eastern Brazil.
