the wing bar. The following are the dimensions of a fine 

 male : — 



Length, 22 - 5 ; expanse, 3-8 ; tail, from vent, 5 ; wing, 11-0; 

 bill, from gape, 3*5 ; at front, 3 - l ; tarsus, 3*5. 



The bill is blackish or greenish horny ; the base of the upper 

 mandible and membrane covering the nares greenish yellow ; 

 the legs and feet yellow. 



A band round the eye, not quite meeting in front but 

 extending backwards behind the eye over the ear-coverts, 

 a line from near the culmen, along the anterior margin 

 of the eyes, over the gape and under the cheeks, together 

 with the entire chin and throat, pure white, A broad 

 short stripe from the sides of the lower mandible at its 

 base, the lores, and a broad stripe running round over the eyes 

 above the white band already described, and a similar but 

 broader stripe below the eye including the cheeks and nearly 

 the whole of the ear-coverts, deep brown. The posterior ends 

 of these two latter stripes generally meet behind the termina- 

 tion of the backward prolongation of the white eye band, and 

 then run as a narrow dark streak a little way down the neck. 

 All these dark bands are much broader and more strongly 

 developed in this species than in recurvirostris, and generally 

 the color of the present species is everywhere darker than in 

 the Indian bird. The forehead, top and back of the head, 

 hair brown, the shafts darker. The posterior half of the neck, 

 the back and scapulars, earthy brown, somewhat paler than 

 the head, the feathers dark shafted; the anterior half of the 

 neck varying from white above to pale French grey below, the 

 feathers brown shafted. The first five primaries, their greater 

 coverts and the wiuglet, dull umber brown ; the first primary 

 with a two-inch or more white band across both webs not far 

 from the tip, and the rest of the inner web above this nearly 

 all white; second primary similar, but the band less broad 

 and only partially extending on to the outer web, and more 

 brown on the inner web than on the first ; third similar, but 

 less white than the preceding and none on the outer web ; in 

 the fourth and fifth, the white confined to a broad stripe on 

 the outer portion of the inner web, sixth to the tenth primaries, 

 and their greater coverts pure white, the sixth with a browu band 

 on the outer, the tenth with a similar band on both webs 

 towards their tips. The secondaries white on the basal portion, 

 tipped white, more broadly in the earlier, more narrowly in 

 the later ones, and with an oblique hair brown band, inside 

 the tipping occupying but a small portion of the inner web.
