Mango Humming-bird, var. A., Lath. Gen. Syn., vol. ii. p. 759. — lb. Gen. Hist., vol. iv. p. 311. 



It would scarcely be supposed that an island like Jamaica should have a large and powerful member of this 

 group of birds peculiar to it, yet such really appears to be the case, for up to the present time the Lmn- 

 pornis porphijrunis has not been found elsewhere. This fine species differs so essentially from every other 

 known Humming-bird, that no mistake can have occurred on this point ; for not only does the male present 

 an entirely different style of colouring, but those birds which are considered to be the females of this species 

 are also as widely different. These supposed females are indeed equally, if not more brilliantly coloured 

 than the males, an anomaly which has much puzzled not only myself, but other Trochilidists, by one of whom, 

 at least, these birds have been considered so distinct that he has given them a separate appellation, that of 

 Floresi, . 



Few travellers have written more interestingly on the Humming-birds seen by them in a state of nature than 

 P. H. Gosse, Esq. ; in the absence, then, of any knowledge of my own, I cannot do better than copy the fol- 

 lowing details respecting this species from his "Birds of Jamaica" : — " Though occurring at all seasons, I 

 have not found it abundant at any. It affects the lowlands in preference to the mountains, and open places 

 rather than the deep woods ; yet it is rarely seen to frequent the blossoms of herbs or shrubs, but hovers around 

 blossoming trees. The bunch of blossom at the summit of the pole-like Papaw-tree {Carica papaya) is a favourite 

 resort, especially at sunset. This species, when flying, often flirts and flutters the tail in a peculiar manner, 

 and when it hangs perpendicularly in mid-air, the appearance of the broad lustrous feathers, expanded like a 

 fan, is particularly beautiful. The lustrous glow of the neck of the adult male may be unperceived on a care- 

 less examination. In such Humming-birds as I have examined, the iridescence of those portions of the 

 plumage that are changeable is splendid in the ratio of the acuteness of the angle formed by the incident 

 ray of light and the reflected one. I have never met with the nest of this species, but one presented to me 

 by my friend Mr. Hill is now before me. It has evidently been constructed to stand upon a horizontal twig, 

 which the bottom has embraced. It is cylindrical externally, the bottom being flat. Its height is 1^ inch ; 

 its external diameter a little more ; its internal diameter about 1 inch ; the hollow, which is a little overhune; 

 by the margin, is cup-shaped, about iths of an inch deep. It is composed almost entirely of the down of 

 the gigantic silk-cotton tree {JEnodendron anfractnomiii)^ intermixed at the bottom with a little true cotton. 

 The sides are tightly banded round with the threads of spiders' webs, very neatly put on, and the whole 

 exterior is studded with a minute whitish lichen, so profusely as almost entirely to conceal the down, without 

 at all injuring the symmetry of the form. It is a most compact and beautiful little structure." 



I am indebted to Mr. Gosse for the gift of a nest of this species, I believe the one described above, and 

 which is figured on the accompanying Plate. 



The male has the general plumage dark olivaceous brown, glossed with purple ; from the bill through the 

 eye, down each side of the neck, a brilliant purple band ; throat and abdomen blackish brown; a few white 

 feathers at the lower part of the abdomen, and on each flank a small patch of white ; wings purplish brown ; 

 two centre tail feathers bronzy black ; the lateral ones changeable purple, margined at the tip with bronzy 

 black. 



Female similar, but with a mark of changeable purplish green down the throat. 



The Plate represents the two sexes of the size of life. The plant is the Pachijstigma pteledides.
