This appears to be a western representative of the B. tamatia of 

 Cayenne, from which, however, I think it may be fairly separated. 

 MM. Verreaux of Paris have lately received a considerable number 

 of specimens of it from the I'jjper Amazon. They all present the 

 same distinctive characters as are above noticed.

My specimen of this bird was obtained from the MM. Verreaux, 

 and carries the MS. name above quoted, which I have thought it as 

 well to adopt. The characters which sej)arate it from its well-known 

 Brazilian representative arc certainly very slight, but ajjpear to be 

 constant in at least a dozen examples I have examined from the 

 same locality.

Mr. Gould's collection contains two examples of this bird, which 

 he has entrusted to me for comparison \vith its Cayenne representa- 

 tive. It is not, however, without hesitation that I have determined 

 to separate them from it. Besides their larger size and broader 

 breast-band, the white medial square spot extends in the present 

 species only through the three lateral rectrices, with a slight trace of 

 it in the fourth. 



In the Cayenne bird the outer five pairs are all strongly marked 

 thus. The whole plumage of the bird is also generally more intensely 

 black.
