Description. 



In the general cast of its plumage this little bird presents a 

 miHiature resemblance to Thamnophilus maculatus. It is about 

 the size of the Wood-Wren, having the upper mandible of the bill 

 black, and the under horn colour. The witig covers and all the 

 upper plumage is deep black, variegated by numerous tear-shaped 

 spots of pure white. On the Aeorf these spots are so disposed, as 

 to form macular bands over the eyes, leaving the middle of the 

 crown and a stripe above the ears, entirely black. The under 

 plumage is cinereous white, with the middle of the feathers 

 black, particularly on the breast and body, where this black 

 colour forms spots. The quill feathers are brownish, margined 

 by light grey ; and each of the lesser quills is tipt by a round 

 spot of fulvous white. Tail rather lengthened, much graduated, 

 the feathers being moderately pointed; their colour is black tipt 

 with white, and crossed by three interrupted white bauds. Tarsi 

 rather short, weak, and pale. 



Total length 5 inches ; bill, ^ ; wings, 2 ; tail, 2 \ ; tarsi, /^. 



My specimen of this bird was sent me by Dr. Langsdorff, from 

 the Mining District of Brazil. It has all the indications, in the 

 distribution of its colours, of being a male.
