AMAZILIA CERVINIVENTRIS, Gould. 



Fawn-breasted Amazili. 



Amazilius cerviniventris, Gould in Proc. of Zool. Soc, part xxiv. p. 150. 



The Humming-bird figured on the accompanying Plate is a species very recently discovered by M. Salle at 

 Cordova in Mexico, It differs sufficiently from every other to satisfy the most scrupulous as to its 

 distinctness. Less difference occurs in the colouring of the sexes than is observable in most other species, 

 but in this particular it accords with the other members of the genus. Two of the three specimens procured 

 by M. Salle, all of which now form part of my own collection, are said to be males and the third a female ; 

 the latter being principally distinguished from the former by the indistinct mark of blackish-brown near 

 the tips of four of the tail-feathers, namely the two on each side next the middle ones. 



The tips of all the tail-feathers of both sexes are fringed with a bronzy-orange, which is more intense on 

 the middle than on the outer ones, where indeed it becomes almost obsolete. 



This species is about the size of A. Riefferi ; but its bill is less robust, and the chestnut colouring of the 

 tail-feathers is of a somewhat lighter hue ; as also are the under tail-coverts. 



Head, all the upper surface, wing- and upper tail-coverts bronzy-green ; wings purplish-brown ; tail 

 dark chestnut-red, each feather narrowly bordered and tipped with a bronzy lustre, which is of greatest 

 extent and most conspicuous on the two centre tail-feathers; throat and chest luminous green; under 

 surface of the shoulder and flanks dull green ; abdomen and under tail-coverts fawn-colour ; thighs white ; 

 bill reddish-flesh or yellow, at the base merging into brown, and tipped with black. 



The Plate represents two males and a female. The plant is the Gonolobus Martianus.
