ochraceous buff like the sides, but may at once be distinguished by the following 
characters: the top of the head is pale brownish olive like the back (not slate- 
grey) ; the cheeks and ear-coverts are light ochreous (instead of slate-blackish) ; the 
upper mandible light horn-colour (instead of blackish), etc., etc. Besides the type 
from Engenho do Gama, Western Mattogrosso, I have examined an adult female and 
a young male which were obtained at Bom’ Lugar, Rio Puris, in March 1904, and 
are actually preserved in the Para Museum.

Adult males have the lower surface down to the anal region deep black, the 
flanks and under tail-coverts light rufescent brown mottled with ashy. In immature 
males the middle of the abdomen is cinereous mixed with whitish, the feathers of 
the breast show narrow, greyish edges, and the greater upper wing-coverts are 
dusky tipped with cinnamomeons (instead of being uniform chestuut-rafous). 
The female had not been properly described until Dr. J . A. Allen received the 
type of C. rusbyi. His description agrees minutely with the female sent by 
Mr. Hoffmanns, and three others obtained by Natterer near Borba. 
C. melanogaster, by far the finest species of the genus, is only known from the 
Rio Madeira and its tributaries (Rio Beni, R. Machados), and spe, the left bank of 
the Tapajéz (Itaitiba, Villa Braga). The original locality “Cuyaba” requires 
confirmation, ;

This bird agrees with others from Eastern Ecuador and Western cima 
(Rio Javarri) in having the middle of the belly buffy, and the sides '¢ a et 
extent decidedly rufescent brown. Cf. Ménégaux & Hellmayr, Bull, Mus, Paris xi.

Pie that the birds from Amazonia (Eastern Ecuador, Northern Pera, and 
North Brazil) will prove to be separable from the typical race, but I should like to_ 
examine a better series from Cayenne before proposing a name,
