oclii'aceoiis biift' like the sides, but may at once be distinguished by the following 

 characters : the top of the head is jiale broivuish olive like the back (not slate- 

 grey) ; the cheeks and ear-coverts are light ochreons (instead of slate-blackish) ; the 

 upper mandible light horu-colour (instead of blackish), etc., etc. Besides tiie type 

 from Engenho do Gama, Western Mattogrosso, I have examined an adult female and 

 a young male which were obtained at Bom Lugar, Rio Puri'is, in March 1004, and 

 are actually preserved in the Para Museum.

Adult males have the lower surface down to the anal region deep black, the 

 flanks and nnder 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 cinnamomeous (instead of being uniform chestnut-rufous). 



The female had not been properly described until Dr. J. A. Allen received the 

 type of C. rush)/i. His description agrees minutely with the female sent by 

 Mr. Hoffmanns, and three others obtained by Natterer near Borba. 



C. mclanoga.iti'r, by far the finest species of the genus, is only known from the 

 Rio Madeira and its tributaries (Rio Beni, R. Blachados), and from the left bank of 

 the Tapajoz (Itaituba, Villa Braga). The original locality "Cuyaba" reiiuires 

 confirmation.

This bird agrees with others from Eastern Ecuador and Western Brazil 

 (Rio Javarri) in having the middle of the belly buify, and the sides to a large 

 extent deciiledly rufescent brown. Cf. Menegaux k Ilollmayr, IJull. Mas. Paris xi. 

 No. (published January 1900) p. 374. 



I e.xpect that the birds from Amazonia (Eastern Ecuador, Northern Peru, and 

 North Brazil) will prove to be separable from the typical race, but I should like to 

 pxapiine a better series from Cayeuue before proposing a name.
