Dec. 1847.] 333 



Mask forming a frontal band, fully including the eyes and extending to 

 the breast, black, which is also the color of the back, wings and tail. 



Shoulders, rump, upper tail coverts, and entire under surface of the body, 

 (from the breast,) yellow. 



No white on the wings or on any other part of the body. 

 In a specimen which is probably that of a young bird, the black of the 

 chin is mixed with yellow ; no white whatever on any part of the plumage. 

 Total length from tip of bill to end of tail, about 7 inches, wing 3.6-10, 

 tail 3| inches. 

 Hab. Mexico and South America. 



Resembles Icterus cucullatus, Swainson, more than any other species 

 known to me, but I. cucullatus is very conspicuously marked with white on 

 the wings, which is not the case in the species now described. 



The T. cucullatus has black shoulders, its bill also is longer and more 

 slender, and in other respects it is entirely different. 



After a careful examination, with the advantage of the Academy's large 

 collection of Icteri, I am rather surprised that I can find no description 

 which will apply to this species, although I have seen it occasionally in col- 

 lections for the last ten years. 



Of the four specimens now in the collection of the Academy, two from the 

 Rivoli collection are labelled Mexico, one also from that collection is with- 

 out label of any kind, and the fourth was received by me from Brazil. I 

 have also seen specimens said to be from the island of Trinidad.
