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 white; 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 feathers 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 male.—Length (skins), 107-116 (111); wing, 60-67 (63.9); 
tail, 35.5-38.5 (87); 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 Yanque; Adjuntas; 
Utuado; Lares; Mayaguéz). 
* 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. 8. 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. 
5 A nestling (determined to be a male by dissection) is in this plumage. 
¢ Ten specimens. 
@ Four specimens.
