Mr. D. G. Elliot on New Species of Birds. 
above islands. It is nearest allied to the Myiagra plumbea of 
Gould's B. of Austr. ii. pi. 89, but is distinguished by its deeper 
colour, chiefly on the head and throat, and by having the lower 
surface chestnut instead of white. 
5. Megabyas bicolor, D. G. Elliot. 
Niger, nitore nonnullo seneo; uropygii plumis laxis et corpore 
toto subtus albis : rostro nigro : tarsis et pedibus rubris. 
Sp. Ch. Head, back, wings and their under coverts, and tail 
black, with greenish reflexions; rump and entire under parts 
pure white; bill black; tarsi and feet reddish. Of the same 
size as female. 
Remarks. My attention was drawn to this species by M. 
Jules Verreaux, who has described the female under the name of 
Megabyas flammulatus (Revue Zool. 1855, p. 348). This is the 
first time, to my knowledge, that the male has been received; and 
I propose to give to the species the name of Megabyas bicolor, on 
account of the great difference, in the plumage, between the sexes. 
This specimen also was received from Gabon by M. Verreaux. 
6. Platypsaris affinis*, D. G. Elliot. (Plate XIII.) 
Supra cinereo-plumbea: semicristata: dorsi et scapularium 
macula basali albis: subtus cinereo-albescens, collo antico 
roseo; mento paulum albescente; juguli parte laterali 
cinerea: remige secundo brevi, nigricante, margine externo 
et parte interna et macula parva ad ipsam basin albis : 
rostro et pedibus nigris: cauda emarginata. Long, tota 
60; alse 3 45; cauda? 2*9. 
Hab. in Mexico. 
This species of Platypsaris , to which I have given the name 
of affinis, is closely allied to Platypsaris aglaice (La Fresnaye), 
from which, however, it can easily be distinguished by its much 
smaller bill, and the general lighter colour of its plumage, as 
well as the distinct black head, whereas there is little or no 
difference in the adult male of P. aglaice, between the colour 
of the head and back. 
The rose-colour of the throat is brighter in P. affinis, and 
* A series of skins from Vera Cruz recently examined all belonged to 
this bird. On the other hand, a specimen from Oaxaca seems to be what 
Mr. Elliot considers as true P. aglaice. I am not yet convinced of their 
specific distinctness.—(P. L. S.)
