Nos. 5220, 5237. b, c. [ ? ] et S imm. Ponthierville,

Adult. Iris dark hazel ; bill pale yellow ; feet black. 



Immature. Iris dark hazel; bill greyish-green ; feet grey. 



The type specimen of B. sharpei procured by Hamilton 

 in Angola is no doubt an immature male, having the larger 

 bill and large black j^tch on the basal part of the upper 

 and lower mandibles characteristic of that sex, while the 

 casque is scarcely developed. It agrees almost exactly with 

 a male procured near Efulen, Camaroon, by Mr. G. L. Bates, 

 but has a vai'ying amount of black at the base of the four 

 outermost pairs of tail-feathers, while in the Efulen bird, 

 which is probably somewhat older, these are almost pure 

 white. A second male from the River Ja, Camaroon, also 

 procured by Mr. Bates (cf. Sharpe, ' Ibis,^ 1904, p. 609), has 

 the bill similarly coloured, but appears to be a fully adult 

 bird with a well-developed casque terminating abruptly near 

 the point of the culmen. 



The bill of the adult female is much smaller than that 

 of the adult male, and is pale yellow without any black 

 patches at the base ; the casque also is much less developed. 



Bill (measured from gape to tip) in adult male 4*0 inches ; 

 casque 3*7. 



Bill (measured from gape to tip) in adult female 3"3 inches ; 

 casque 2*6. 



Fully adult birds of both sexes have the four outer pairs 

 of tail-feathers pure white, or with only slight traces of 

 black at the extreme base of some of the feathers.
