Two specimens are all that are known of this rare and singular Humming Bird ; of 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 of interest ; upon his replying in the affirmative the body was forwarded, and the bird 

 may now be seen, beautifully mounted and without a trace of 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 of the Isthmus of Panama to David on that of the Pacific, was induced to 

 deviate in search of novelties to the Rovalo peak, where his labours were rewarded by the discovery, among 

 other interesting objects, of this very curious bird. 



Mr. Loddiges' specimen formed the subject of M. Bourcier's description, and the figures in the accom- 

 panying Plate are taken from my own. Judging from the members of the genus Glaucis, to which the 

 present form is nearly allied, but little difference will be found to exist in the colouring of 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 

 of the various Orchidaceous and other plants with curved tubular flowers so abundant in the country the 

 bird inhabits, and for exploring which a bill of any other form would be useless. 



At present nothing is known of its habits ; we may reasonably hope that this desideratum will be obtained 

 before the close of the present work, in which case the additional information will be found in the general 

 resume. 



Crown of the head and a small occipital crest brownish black, with a faint spot of buff at the end of each 

 feather ; back of the neck, back, wing-coverts and upper tail-coverts dark shining huffy green ; wings 

 purple brown ; on the tip of the secondary nearest the body a triangular spot of huffy 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 

 laro-ely 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 of the basal two-thirds of the lower mandible which is 



yellow. 



The figures represent the bird in two different positions on the Coryanthes spechsa.
