Obs From specimens now in the Berlin Museum I have made 

 the following nofcs :— The type specimen of D. lexcopsis, Cab., was 

 obtamea by Baron v. rl. Decken near Zanzibar. Ft has the win-- 

 coyerts totally black, the primary and secondary quills faintly edged 

 with whitish ; the lower back, rump, ear-coverts, cheeks, orbital 

 prteocular region, nostrils, and all the underparts are pure white ■ 

 a small grey spot in front of the eye. 



A nestling, obtained by Dr. Fischer near Malindi, June 9th is 

 pure white below, and aU the quills of the wings have broad whitish 

 margins ; supraorbital, loral, and auricular regions white 



Another bird, marked by Dr. Fischer " fern, juv.," has the loral 

 region white, but with a faint greyish prffiocular spot. 



An adult male (\Yitu : Fischer) has the loral region quite black,

Male, moulting (from ^ifombas, July 4, 1877 : Dr. Fischer) 

 V\ ings and their coverts entirely black, except the bases of the 

 inner webs, aU the older quiUs being visibly abraded and showin- 

 no white margins whatever ; scapulars white at base and outer web" 

 torming a conspicuous white shoulder-patch : iris red ; biU and 

 claws black ; feet leaden grey. Length of culmen 0-8 inch, wing 3 

 tail 2-b, tarsus 0-92. 



AduU male (Lamo : J. Kirk). Like the specimen from Mombas 

 but the outer webs of the primaries are just visibly edged with 

 white, so that the wing, when closed, shows a whitish hue If we 

 compare this bird with the old bird in moult, mentioned above it 

 seems that the absence or presence of these narrow white mar-ins 

 in the male is only a question of age of the feathers. 



Female (Lamo). Has the lower back, rump, and flanks washed 

 with grey ; white lores, with a black prteocular spot ; most of the 

 wing-coverts and quills are narrowly, the secondary quills and 

 median coverts somewhat more broadly, margined A^ith pure white 

 in ail these three specimens the under wing-coverts are pure 

 white, with the exception of those near the edge of the wing which 

 are blackish and form a small patch.
