GENERA AND SPECIES. 



Trochilus Calliope, Gould in Proceeds. Zool. 

 Soc. 1847. 



Upper surface green ; wings and tail, greyish- 

 brown ; feathers of the throat elongated, narrow, 

 and of a rich pinky scarlet, with white bases, 

 arranged in a star form ; breast, centre of the 

 abdomen, and under tail-coverts, white ; flanks, 

 buify-white ; bill and feet, blackish brown. 



Total length, 2J inches ; bill, f ; tail, 1. In 

 G-ould's cabinet. 



This is a very diminutive species, much 

 smaller than Tr. Lucifer (0. Cyanopogori), but 

 of precisely the same form. 



Locality : Mexico. 



At the end of his list of the species of the 

 genus Calothorax, the Prince of Canino notices 

 Ornismya Elisa, Lesson, 1839; and Trochilus 

 Yarrelli, and Tr. Evelyna, of Bourcier, in Pro- 

 ceeds. Zool. Soc. 1847, with a query as to their 

 true characters and generic rank. These two 

 last species are in the cabinet of Mr. Loddiges, 

 but, as far as our judgment is concerned, will 

 not come under the present genus. 



The Trochilus Tarrelli is thus described. 

 Adult male : beak black, straight, cylindrical ; 

 head round ; the upper part of the body entirely 

 grey, with a slight reflexion of glossy yellowish- 

 green ; throat and gorget of a brilliant greenish - 

 blue, passing into violet in the centre ; sides of 

 the neck, breast, and abdomen whitish ; undt
