88 On an apparently new Species of Eucephala. 



Length 3| inches, bill f , wing 2\, tail \\. 



Hab. Brazil? 



This species appears to be intermediate between E. ccerulea 

 and E. hypocyanea, as represented by the type in Mr. Gould's 

 collection. From the first of these it can be readily distin- 

 guished by the rich blue of the imderparts, which is metallic 

 green in E. ccerulea, the blue being confined in that species 

 to a spot on the chin. To the second of the above-named 

 species it bears a closer affinity, but difiers in the dull green 

 upper tail-coverts, the metallic green under tail-coverts, and 

 buffy white thighs, these parts in E. hypocyanea being re- 

 spectively reddish bronze, brownish black with bronzy tips, 

 and brown. Beside these differences, the blue of the under 

 surface is not of the same colour, and also differently dispersed 

 over the plumage. 



The species of this genus appear to be as follows : — 



1. Eucephala GRAYi (Delattre & Bourc.) . 

 Hab. Columbia. 



Recognizable by its blue head. 



2. Eucephala sMARAODO-CiERULEA, Gould.

 one specimen in that of the late M. E. Verreaux, of Paris.
