Humming-birds of the West Indies, 353 



collection, I am unable to consider that there is more than one 

 species of this form. The difference in the shade of colour is 

 what may be seen in many species of Humming-birds, notably in 

 such a one as Calothorax cyanopogon, where the luminous throat- 

 mark in individuals varies greatly, and cannot be deemed a 

 specific character. 



Mr. Gould has also described two specimens in his collection 

 as E. longirostris. These were kindly shown to Mr. Salvin and 

 myself: and we compared them carefully with examples of E. 

 holosericeus. They are unfortunately in very bad condition, and 

 the frontal feathers of the best one are wanting ; allowing for 

 this, we ascertained that the bill was but very little longer than 

 those of the common species. Not thinking this a sufficient 

 character to establish the species, I have placed E. longirostris 

 among the synonyms of E. holosericeus.

Hab. Jamaica. 



This handsome bird, conspicuous for the lengthened plumes 

 of the lateral tail-feathers, is one of the commonest species of the 

 island of Jamaica, where alone it is found. The female is a plain 

 little bird, with a white breast, the long tail-feathers being absent. 



DORICHA EVELYNS. 



Trochilus evelyme, Bourc. Proc. Zool. Soc. 1847, p. 44. 



Trochilus bahamensis, Bryant, Proc. Nat.-Hist. Soc. Boston,

Doricha evelynce, Gould, i\Ion. Troch. vol. iii. pi. civi. 



Hab. Nassau and New Providence, Bahamas {Bryant). 



This species still remains very rare in collections, only the 

 dried bodies of the birds having been received; good skins have 

 never yet been sent to Europe.
