term mango, however, is evidently the one applied first to the 

 species from Jamaica ; and if the law of priority has any force, 

 the porphyrurus of Shaw must sink into a synonym, and the 

 present species be henceforth known as Lampornis mango, and the 

 one usually called by that name will bear that of Lamptornis vio- 

 licauda, it being the Trochilus violicauda of Boddaert, L. alhus 

 of Gmelin.

Hab. ? 



I described this species in the ' Annals & Magazine of Natural 

 History ' as above cited, under the name of Chrysolampis chloro- 

 leemus, placing it in that genus after consulting with i\Ir. Gould, 

 who considered it belonged there, on account of the feathers 

 protruding forward upon the bill, somewhat like those in C. mos- 

 chitus. But after further investigation, as suggested by Messrs. 

 Salvin and Sclater, Ibis, 1871, p. 429, I am satisfied that its pro- 

 per position is among the species of the present genus, and comes 

 nearest to the Lampornis dominions ; the specific name of chloro- 

 lcemus, having been already bestowed on a bird of a very closely 

 allied genus, cannot well be retained without danger of creating 

 confusion ; and I therefore propose to substitute for it the 

 appellation of calosoma, so that the species will henceforth be 

 known as Lampornis calosoma. 



The habitat of this species is unknown ; but it is not unlikely 

 that it may be a native of some one of the West-Indian Islands 

 of whose ornithology we at present know nothing. If this sup- 

 position should prove to be correct, a fine field still remains 

 unexplored for some enterprising naturalist ; for among the mem- 

 bers of the genus Lampornis the present species is one of the very 

 handsomest, and doubtless many equally fine birds in this and 

 other families are still unknown to science, to reward the re- 

 searches of the explorer. I give a short description of the species, 

 in order to bring it more prominently before ornithologists, in 

 hopes that other specimens may be procured, the type in my 

 collection remaining as yet unique.
