DENDROPHASSA VERNANS ADINA, new subspecies. 



Subspecific characters. — Similar to Dendropliassa 1 vernans vernans, 

 from the Philippine Islands, but much larger; male duller, averaging 

 less greenish above, and of a decidedly paler yellow on abdomen; 

 female averaging duller, much less greenish (more plumbeous) 

 above, and much paler, duller, less greenish and yellowish below, 

 the center of abdomen generally whitish. 



Description.— Type, adult male, No. 171020, U.S.N.M.; Pulo Mata, 

 Anamba Islands, August 29, 1899 ; Doctor W. L. Abbott. Pileum, sides 

 of head, chin, and throat, plumbeous, rather darker on occiput, the 

 post-ocular region washed with vinaceous ; a collar around hind neck 

 and jugulum, broadening on the sides of the throat and neck, vina- 

 oeous heliotrope; interscapulum, back, scapulars, and rump, dull 

 olive green, with a plumbeous wash, and rather brighter posteriorly ; 

 upper tail-coverts isabella color, gradually merging into the olive 

 green of rump; tail slate gray, with a broad subterminal band of 

 black, and tipped narrowly with slate color; wing-quills, except ter- 

 tials, slate black, the outer primaries brownish black distalry, all the 

 quills shading inwardly into slate gray basally; tertials and wing- 

 coverts grayish olive green, like the back, the bend of wing washed 

 with plumbeous, the greater coverts and tertials conspicuously mar- 

 gined distalry on outer webs with pale yellow; chest tawny ochra- 

 ceous; lower breast and upper abdomen light yellowish apple green; 

 sides deep plumbeous washed with greenish; lower abdomen and 

 flanks sulphur yellow, the latter broadly streaked with greenish slate 

 color ; lower tail-coverts light reddish chestnut ; under surface of wing, 

 including wing-coverts and axillars, slate gray. 



Doctor Abbott obtained six males and five females from the islands 

 of Siantan, Mata, Mobur, and a small islet near Pulo Mobur. The 

 males show no differences in color between specimens from the differ- 

 ent islands, although there is some individual variation in the depth 

 of shades both above and below. The same is true of the females, 

 but the individual variation in them is more marked. One female, 

 No. 170928, U.S.N.M., from Pulo Siantan, is much more greenish 

 above than any of the others, as well as darker below and washed with 

 brownish across the breast; and it is evidently immature, as the 

 tawny-tipped feathers on the sides of the neck indicate. According 

 to data on the labels of the males, the iris is sometimes red, some- 

 times in two rings, the inner blue, the outer pink; the feet "red" or 

 "dark red;" "bill leaden; cere yellow." Females have the iris yel- 

 low, the feet red. On the islet off the coast of Pulo Mobur, where 

 Doctor Abbott took some of these birds, hundreds of them roosted 

 regularly.
