The following are dimensions, &c., recorded in the flesh :— 



Males. — Length, 5*4 to 5*75 ; expanse, 8'5 to 9*25 ; tail 

 from vent, 1*82 to 2'1 ; wing, 2'8 to 30; tarsus, 1*0 to l'l ;

 1-05 ; bill from gape, 07 to 0-72 ; weight, 0-5 oz. 



Legs, feet and claws fleshy white ; upper mandible, in the 

 male dark, in the female pale, horny brown ; lower mandible 

 fleshy white, or pale brown ; gape fleshy white : one male had 

 the upper mandible horny black ; irides deep brown. 



The adult male has the chin, throat, breast, abdomen, vent, 

 and lower tail-coverts, pure white ; the lores, feathers at the base 

 of the lower mandible, and a line down the sides of the throat 

 bounding the white, black ; forehead, crown, occiput, greater 

 portion of the ear-coverts (though the black stripe spreads to a 

 certain extent sometimes over part of these), back and sides of 

 the neck, back, scapulars, wing-coverts, rump and upper tail- 

 coverts, uniform dull pale cyaneous ; a trace of a pale blue stripe 

 from the nostrils over the eyes, and passing over the ear-coverts ; 

 quills and tail feathers hair brown, more or less overlaid with 

 this same dull cyaneous. In certain lights the bird looks more 

 of a dull indigo blue ; in others more of a dull leaden blue. 

 Sides of the breast, body, axillaries, wing-lining and flanks 

 dusky cyaneous. 



The female also has the lower parts white, but the sides of 

 the throat and the entire breast are faintly tinged with fulvous, 

 and the feathers are narrowly margined at their tips with pale 

 brownish olive, producing, more especially on the breast,a squamat- 

 ed appearance ; the whole of the top and back of the head, sides 

 and back of the neck, back, scapulars, wing-coverts, rump and 

 upper tail-coverts a nearly uniform greenish olive brown ; the 

 tips of the longest upper tail-coverts only, sometimes margined 

 with a slightly ferruginous shade ; quills hair brown ; both webs 

 of the tertiaries, and more or less of the outer webs of the 

 secondaries and of the primary greater coverts, a more rufes- 

 cent olive brown, generally paler a,gain, and even inclining to 

 greyish on the margins of the outer webs of the tertiaries ; 

 tail olive brown, purer and more of a hair brown on the inner 

 webs, and sometimes with a greyish shade along the margins 

 of the lateral tail feathers towards their bases. 



The young male is very similar to the female, jbnt has the up- 

 per tail-coverts dull slaty blue, and I may here note that the 

 " Brachypteryx vet Cai,lene, sp. ,'?" of the late Captain Beavan 

 procured by him at Zwagaben, and described, Ibis, 1870, p. 321, 

 is unmistakably a young male of this present species. His
