138 MR. CASSIN'S DESCRIPTIONS OF THREE NEW SPECIES OF ICTERUS. 



Resembles Icterus cucullatus, Swainson, more than any other species known to 

 me, but /. cucullatus is very conspicuously marked with white on the wings, which 

 is not the case in the species now described. 



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

 in other respects 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 collections 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 without 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. 



PI. 17.

Hab. Prope Bogota, in Nova Grenada. 



Adult. Mask broad, forming a frontal band, fully including the eyes, and extending to the breast, fine 

 black. Wings and tail black, with no white marks whatever. Head above, entire body above and 

 below from the breast, and shoulders bright lemon yellow, no white on any part of the plumage. 

 Young. Yellow, the whole plumage tinged with dull orange or gamboge colour. Wings edged with 

 greenish. Very young. Yellow parts of plumage paler, in some parts nearly white, black on the 

 throat scarcely apparent. 



Total length, skin of adult, from tip of bill to end of tail about 8 inches, wing 1 4-10, tail 4 inches. 



Hab. Bogota in New Grenada. 



Resembles Icterus Xanthornus, (Linn.) more than any other species with which I 

 am acquainted or have found described, but is larger, and has the mask much 

 broader. 



In /. Xanthornus, the gular black scarcely exceeds the width of the under 

 mandible, but in the species now described, it fully includes the eyes and the whole 

 base of the bill. /. Xanthornus has also white markings on the wings, which is not 

 the case in any state of plumage represented by the five specimens now described. 



I have named this beautiful species in honour of Jacob P. Giraud, Jr., Esq., of the 

 city of New York, author of " The Birds of Long Island," and other important 

 contributions to American Ornithology.
