Cervantes. April, 1S«'>7. 



A single female specimen of what I suppose to be the above 

 Bpeciea has lately been received from Dr. Frantzius. I have 

 compared it with the type in the M usenm of the Boston Soc. <>!' 

 N. !!.. and find it differs from it, in being much blacker above, 

 and in having the central part of the breast and abdomen pale- 

 yellowish fulvous, instead of white, as in the type; the ridge of 

 the upper mandible is black as far down as on a line with the 

 nostrils, the remaiuder of the bill is bright orange; in the type, 

 the black color on the upper mandible extends much nearer to 

 the edges ; these with the under mandible are yellowish-white. 

 The type may have faded, but as they agree in size and in dis- 

 tribution of color.-, they are probably identical. Possibly the 

 difference in colors raav be seasonal. 



Mr. ( ». Salvin i/'. /. &, l s »'.7. p. L32) notices apparently the 

 same species, received from v*eragnas, which he says: "Agrees 

 closely with Mr. Sclater's example from Ecuador. The bill, 

 however, is Bomewhat Larger, and in this fresh specimen, of a 

 brighter orange-color."
