Two specimens are all that are known o f this rare and singular Humming Bird ; o f these one is in the
Loddigesian Collection, the other in my own. I believe the former was sent to Mr. Loddiges direct from
Bogota, and that in rather a singular manner :—the head was first sent, with a request to know if it
belonged to a species o f interest ; upon his replying in the affirmative the body was forwarded, and the bird
may now be seen, beautifully mounted and without a trace o f the severe treatment to which it had been
subjected. My own specimen was procured in a very different locality, having been sent from Veragua in
Central America by the well-known botanical traveller M. Warszewiez, who, while crossing from Bocco
del Toro on the Atlantic side o f the Isthmus o f Panama to David on that o f the Pacific, was induced to
deviate in search o f novelties to the Rovaio peak, where his labours were rewarded by the discovery, among
other interesting objects, o f this very curious bird.
Mr. Loddiges’ specimen formed the subject o f M. Bourcier’s description, and the figures in the accompanying
Plate are taken from my own. - Judging from the members o f the genus Glaucis, to which the
present form is nearly allied, but little difference will be found to exist in the colouring o f the sexes. It is
evident that its singularly-shaped bill is adapted for some special purpose, and we may readily infer that it
has been expressly formed to enable the bird to obtain its food from the deep and remarkably-shaped flowers
o f the various Orchidaceous and other plants with curved tubular flowers so abundant in the country the
bird inhabits, and for exploring which a bill o f any other form would be useless.
At present nothing is known o f its habits ; we may reasonably hope that this desideratum will be obtained
before the close o f the present work, in which case the additional information will be found in the general
résumé.
Grown o f the head and a small occipital crest brownish black, with a faint spot o f buff at the end of each
feather ; back o f the neck, back, wing-coverts and upper tail-coverts dark shining buffy green ; wings
purple-brown ; on the tip o f the secondary nearest the body a triangular spot o f buffy white, and on the
next on each side a still smaller spot ; two central tail-feathers dark glossy green slightly tipped with white ;
the remaining tail-feathers dark glossy green on their outer webs, greenish brown on their inner webs, and
largely tipped with white ; under surface brownish black, striated with dark buff on the throat and breast,
and with white on the abdomen and flanks ; under tail-coverts brown fringed with buff, and with a line of
buff down the shaft ; bill black, with the exception o f the basal two-thirds o f the lower mandible which is
yellow.
The figures represent the bird in two different positions on the Coryanthes speciosa.
