Adult male. Above black, glossed with green ; about ouc quarter 

 of the basal portion of the primaries white, forming a broad band 

 halfway across the wing ; tail-feathers with white ends, broadest 

 on the outer ones : beneath white, generally washed with buff and 

 with a dusky shade near the back of the thigh-coverts ; the dusky 

 bases of the feathers often showing through, and faintly-developed 

 shaft-stripes on the throat being sometimes visible ; under wing- 

 coverts buff, the lower series dusky black : " iris dark brown ; bill 

 black ; legs plumbeous brown " (Butler). Total length 12'8 inches, 

 culmcn 0"9, wing 6, tail 7"2, tarsus l-l. 



Adult female. Similar to the male. Total length 12'75 inches, 

 wing 5-8, tail O'TS, tarsus 1. 



Nestling. Above brown, slightly darker on the crown, and more 

 ashy on the forehead ; wings with a few of the feathers broadly 

 tipped with buff, and with no white base to the quills; tail brown, 

 passing into buff on the outer feathers ; sides of the head brown ; 

 throat grey, shading into buff on the remainder of the underparts : 

 bill and legs yellow. Total length 6*8 inches, wing '3-2. 



Full-grown young. Very similar in plumage to the nestling, but 

 with the pale bases to the primaries as in the adult, but fulvcscent 

 in colour : all the tail-feathers with fulvous tips, broadest towards 

 the outer ones ; the grey of the throat is more restricted to the 

 region of the chin : bill and legs darker, the upper mandible and

Indian specimens of C. jacobinus arc precisely similar to African, 

 The wing in both sexes varies from 5'4 to G inches in Indian 

 examples, the Ceylonese birds being rather smaller than those from 

 the Indian Peninsula. In two instances the wing is 6-1 inches in 

 length, but the sex is not marked in either case. African birds 

 have similar dimensions, the largest specimen being from Biballa 

 with a wing of 6"3 inches.
