In form and general contour the Phaéthornis Augusti is so nearly allied to the P. Pretrei, that were skeletons
of both placed side by side, I apprehend it would be most difficult if not impossible to distinguish one from
the other; still I have no doubt as to their specific value, and I am quite sure that no ornithologist would
question their being quite distinct. They beautifully represent each other in the countries they respectively
inhabit. The present species, P. Augusti, is a native of the rich countries of Venezuela and Caraccas.
I have never seen it in collections from Bogota, or any of the more elevated regions ; we may consequently
infer that the forests of the lowland countries I have mentioned constitute its principal if not sole habitat.
If the P. Augusti and P. Pretrei differ at all in size, the former may be considered the smallest; it also
differs from its near ally in being rather less beautifully bronzed on the upper surface, in having narrower
central tail-feathers, and especially in the hue of the under surface, which is lively grey instead of rich fawn
colour, a feature by which it may be at once distinguished. This somewhat rare species was described for
the first time by M. Bourcier, in 1847, when it was dedicated by him to M. Auguste Salle, an enterprising
traveller who collected numerous species of the Trochilide and other groups of birds during his journeys
into the interior of Central America.

As is the case with the other members of the genus, the sexes are alike in plumage, and nearly so in size:
figures of both are given on the accompanying Plate. The plant is the Stemonacanthus macrophyllus, which

is very generally diffused over the northern parts of South America.

Upper surface greyish bronze, becoming more bronzy on the back; upper tail-coverts rust-red; wings
purplish brown; central tail-feathers bronze, largely tipped with white and clouded with black at the junc-
tion of the two colours; the lateral feathers black at the base, crossed obliquely with black and tipped with
white, the extent of the white increasing as the feathers approach the centre, and conspicuously so on those
next the two middle ones ; stripe above and another below the eye white ; lores and ear-coverts black ; under
surface ashy grey, with a lighter streak down the throat ; upper mandible and terminal fourth of the under
mandible black ; basal three-fourths of the under mandible blood-red.

The figures are of the natural size.
