On an apparently new Species of Encephala. 
Length 3-g- inches, bill f, wing 2±, tail 1-1-. 
Hob. Brazil? 
This species appears to he 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 underparts, 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 differs in the dull green 
upper tail-coverts, the metallic green under tail-coverts, and 
huffy 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 smaragdo-CjERulea, Gould. 
Hab. Brazil.

one specimen in that of the late M. E. Yerreaux, of Paris. 
3. Eucephala chlorocephala (Bourc.). 
Hab. Guaranda, in Ecuador, according to Bourcier. 
Specimen in Mr. Gould's collection. 
4. Eucephala c^eruleo-lavata, Gould.
