GENEEA AND SPECIES. 165 



The second species is described in the same 

 work f vol. i. p. 97, pi. 8. 



This genus has received the titles Sapkirs and 

 Smaragdites from the prevalence of the colours 

 of these gems on the plumage. The bill is 

 straight ; the feet small ; the wings are moderate 

 and falciform: the tail rather broad, but not 

 long ; it is square, or nearly so, at the apex. 



Several new species have recently been de- 

 scribed by Bourcier and others". Of these, one 

 of the most remarkable is the Trochilus Caroli 

 of Bourcier. The description is as follows : 

 Adult male. Beak black, straight, and cylin- 

 drical ; the top of the head, the scapularies, and 

 back of a dull green, slightly bronzed, the throat 

 and chest presenting a gorget of brilliant rufous, 

 with gem-like effulgence; under the eye is a 

 white mark ; the lower parts of the body are 

 of a deep grey washed with green ; under tail- 

 coverts whitish, grey in the centre. Wings 

 falciform, of a greyish violet. Tail forked ; the 

 four intermediate feathers graduated, and of a 

 bronzy-green; the rest black, with violet re- 

 flexions ; the external have the outer vane at its 

 extremity washed with yellow. Feet black. 



The locality, whence the specimen (in the col- 

 lection of Mr. Edward Wilson) from which M. 

 Bourcier took his description, does not appear to 

 have been ascertained.
