TANAGRINE GENUS CALLISTE. 
ing to M. Bourcier a specimen of the true ruficervix, he informed 
me, that the one he had brought home, which Prince Canino had 
described, was decidedly different, having white ear-coverts.

Gray’s Gen. Supp. p. 17. 
Supra atra; capite colloque viridi-ceruleis, sincipite macula 
dilute stramined nitente; dorso nigerrimo; uropygio ceruleo ; 
alis nigris ex yiolaceo eseruleo marginatis; tectricibus superioribus 
ceruleig resplendentibus, subtis cerulea, gutture cinereo layato. 
Habitat, Eastern Peru (Tsch.); Bolivia (Bridges). 
The only two specimens I have seen of this species are in the 
Knowsley collection: they were brought from Bolivia by Mr. 
Bridges. The species appears to me to come very near Calliste 
ruficervin ; indeed, the Prince Canino (Compt. Rend. Ac. Sc. Par. 
1851, Jan. 20), states them to be synonymous; but the present 
Species may be distinguished by its black back, and want of the 
pale rufous colouring of vent and crissum.
