Trochilus glaucopis Gmelin. 
Trochilus glaucopis, Gmelin, edition The Blue 
Fronted Humming-Bird, Trochilus frontalis, Latham, 
General History, vol. iv. p. 352 Oiseau-mouche glau- 
cope. Lesson, Histoire Naturelle des Oiseaux-mouches, 
P. 175, Pis. Iviii-lix. 
The forehead of this species is of a rich metallic 
blue, with violet reflections ; the upper parts of the 
body are of a rather dull green, but which, accord- 
ing to Dr Latham, is darker in some specimens, and 
in others nearly of the same tint with the lower 
parts. The lower parts are bright emerald green, with 
the feathers on the throat and breast in the form of 
scales ; the vent and under tail coverts are greyish 
white ; the tail is deeply forked, the feathers com- 
posing it broad, but graduated at the tips; the colour 
is an intense steel blue. 
The only discrepancy between the description of 
Lesson, who has figured both sexes, and that of Dr 
Latham, is, that the latter describes the legs fea- 
thered to the toes, the former has drawn them un- 
plumed. 
The female wants the blue upon the crown, which 
is of the same uniform green with the upper parts ; 
the throat, breast, and belly, are of a dull grey, 
dashed with green on the flanks, and the tail is 
greenish above, with a blue tip.
