 Ibis, 1892, p. 86 (type). 



Adult male. Forehead, crown, and occiput very delicate French 

 grey, slightly paler on the forehead ; sides of the head, including 

 superciliary stripes, throat, neck, upper back, and underparts 

 yellowish green, greyer on the upper hack, yellower on the under- 

 parts ; middle of the back, scapulars, and some of the inner coverts 

 maroon ; lower back, rump, and upper tail-coverts yellowish olive ; 

 feathers of the flanks olive, edged on both sides with yellowish 

 white ; under tail-coverts olive, with broad yellowish-white edges 

 and narrow yellowish margins ; smaller and median wing-coverts 

 ulive, the latter and the greater wing-coverts, and also the second- 

 aries, edged with yellow ; greater wing-coverts and quills black ; 

 under wing-coverts and quills underneath lead-grey ; central 

 tail-feathers yellowish olive like the rump, the rest of the tail- 

 feathers with broad grey tips, above these black, but more or less 

 suffused along the edges and at the base of the outer webs with 

 yellowish olive ; tail below blackish, with a broad apical grey band : 

 " legs and feet purplish pink ; bill pale leaden blue, almost white at 

 tip, darker and tinged greenish at the base ; the irides have three 

 rings — the first pale, the second darker blue, and the third pinkish 

 buff" (Hume). Total length 13-5 to 11*5 inches, wing 7T2 to 6*5, 

 tail 4-4 to 3-5, bill 0-85 to 074, tarsus 1 to 0-82. 



Female. Differs from the male in having no maroon colour on the 

 back, scapulars, and inner wing-coverts, which are of an olive 

 colour like the smaller upper wing-coverts of the male. 



Young birds have the back olive-green with no maroon in the 

 male; the grey colour of the head is more or less tinged with 

 green. 



According to Mr. Hume, the Xicobar birds differ from the 

 Andaman ones in having less yellow on the outer margins of the 

 secondaries, and generally also on those of the greater coverts, but 

 I have failed to find that such is the case.
