parts more whitish, the sides and flanks with much less ochraceous. 
Female very much paler, duller, and more grayish above than the 
same sex of Cyorms banyumas philippinensis, with ochraceous of 
lower surface lighter, and that of lower breast, sides, and flanks much 
less extensive, the sides and flanks with very little; lores dull grayish 
instead of white. 
Descruption.—Type, adult male, No. 171095, U.S.N.M.; Pulo 
Jimaja, Anamba Islands, September 22, 1899; Dr. W. L. Abbott. 
Sides of head and neck, with entire upper parts (except forehead) 
rather light, grayish, indigo blue; forehead and short superciliary 
stripe azure blue; lores and nasal plumes black; remiges and rectrices 
grayish clove brown, all edged externally with the blue of the upper 
parts; lesser and median wing-coverts cobalt blue; remaining wing- 
coverts like the secondaries; chin and moustachial stripes deep blue 
black; throat, jugulum, and upper breast, ochraceous; rest of lower 
surface white, laterally washed with ochraceous; under wing-coverts 
buffy white, the feathers centrally fuscous, the edge of wing beneath 
fuscous mixed with whitish, buff, and blue; axillars buff; ‘‘bill black, 
feet brownish lavender.” 
The male of this new race differs from the male of Cyornis ba- 
nyumas banyumas im somewhat lighter blue upper surface; in pure 
white median posterior lower parts, including the crissum; and very 
much less extensively ochraceous sides and flanks. The female 
differs from that of Cyornis banyumas banyumas m the much more 
bluish gray Gnstead of brownish gray) upper surface, the tail exter- 
nally blue instead of dull ferrugmous; and in practically pure white 
instead of ochraceous abdomen and crissum. 'The male intergrades 
in color with Cyornis banyumas banywmas through Cyorns banyumas 
philippinensis and Cyornis banyumas mindorensis Mearns; while the 
female is intermediate between Cyornis banyumas philippinensis and 
Cyornis banyumas banyumas, though nearer the former. <A trinomial 
seems best to express this bird’s relationships. 
There is considerably more difference between the sexes in this 
form than in C. b. philippinensis, the female being relatively as well 
as actually much paler and more grayish above. Two males (Nos. 
171004 and 170961, U.S.N.M.) in part juvenal, part first autumn 
plumage, differ from the adults of the same sex in having the throat 
and chin whitish, the tawny of breast more or less mixed with black- 
ish, this chiefly in the form of scale-like feather edgigs; many of the 
superior wing-coverts and some of the tertials with broad apical 
spots of ochraceous; and the feathers of head and hind-neck with 
broad shaft streaks or apical spots of tawny or ochraceous. Two 
immature females (Nos. 170910 and 170967, U.S.N.M.) differ from 
adult females in their paler anterior lower parts and duller, more 
brownish upper surface. There is comparatively little individual
