ANTHRACOTHORAX VIRIDIS (Audebert and Vieillot). 



GREEN MANGO. 



Adults (sexes alike). °- — Above metallic green, bronze-green, or 

 (rarely) bronze, duller on pileum, the lower rump and upper tail- 

 coverts purer green (metallic grass green or sea green) ; tail metallic 

 blue-black or dark steel blue, the lateral rectrices sometimes very 

 narrowly margined at tip with grayish or grayish wliite; remiges 

 dusky brownish slate, very faintly glossed with violet; under parts 

 metallic bluish green (french green or between grass green and sea 

 green), the under tail-coverts sometimes narrowly margined ter- 

 minally with whitish; femoral and lumbar tufts white (the latter 

 small and concealed); bill black; iris dark brown; feet dusky. 



Young. — Not materially different in coloration from adults, but 

 some specimens, at least, have the feathei-s of the under parts narrowly 

 and very indistinctly margined terminally with pale grayish brown, 

 or else have the green of the anterior under parts darker and duller. ^ 



Adult maZe.— Length (skins), 107-116 (111); wing, 60-67 (63.9); 

 tail, 35.5-38.5 (37); culmen, 23-25 (24.2). « 



Adult female. —Length, (skins), 104-117 (112); wing, 58.5-63 

 (60.1); tail, 33.5-37 (35.1); culmen, 25-27 (25.9).'^ 



Island of Porto Rico, Greater Antilles (El Yunque; Ad juntas; 

 Utuado; Lares; Mayaguez). 



o Not only have Gould (Monog. Troch., ii) but also Elliot, Cory, Salvin (Cat. Birds 

 Brit. Mus., xvi, 100), and Hartert (Tierreich, Aves, Lief. 9, 100) described the 

 adult female of this species as being pale gray beneath. Undoubtedly they are 

 wrong, for all the specimens sexed as female in the U. S. National Museum (one of 

 them with the determination of sex emphasized) are precisely like adult males in 

 coloration, and even a young bird which had not yet left the nest (a male, however) 

 is not appreciably different! Numerous specimens in the U. S. National Museum 

 corresponding with the descriptions of the alleged female of A. viridis by the authors 

 mentioned undoubtedly belong to A. aurulentus, the adult female of which has little 

 if any chestnut or rufous on the rectrices. 



b A nestling (determined to be a male by dissection) is in this plumage. 



c Ten specimens. 



^ Four specimens.
