however, vary among themselves in the amount of white on 
the quills, whieh is the clistinetion given by Herr Martens ; 
and this variation in the amount of white leads me to eon- 
sider that his H. finschi and the three birds from Baron von 
Hiigel are only aberrations of H. longirostrisJ’ 
Mr. Ernst Hautert reeorded the oceurrenee of a speeimen 
of Grallina picata on the little island of Koer in the Key 
group. 
Mr. Hartert also exhibited the types of three new birds 
eolleeted near Gambaga, Gold Coast Hinterland, whieh he 
named and eharaeterized as follows : — 
CoSSYPHA GIFFARDI, Sp. n. 
Similar to C. alhicapilla from Senegambia, but differing in 
having much narrower white tips to the feathers of the 
crown and occiput, so that these parts do not appear white, 
but black with white crescentic bars. Wings and tail longer 
than in C. alhicapilla. Wing 135-137 mm., tail 145-148. 
Sexes alike. This form is probably a representative of 
C. alhicapilla. 
HeLIOCORYS MODESTA GIFFARDI, Sp. n. 
Closely allied to H. modesta, of which it is evidently only 
a sub-species, but differs in being altogether paler and more 
sandy in coloration ; the breast is less heavily spotted with 
black, the underside paler, the wing 2 or 3 mm. shorter. 
Bessonornis (? Cossypha) gambag^e, sp. n. 
Very similar to Bessonornis modesta, Shelley, from Nyasa- 
land, but differing in its rusty rufous flanks and under tail- 
coverts. The lateral rectrices have not a complete bar across 
the tips, but only an elongate blackish mark on the outer 
webs and a small blackish spot on the inner web of the 
outermost rectrix. The wing-quills and larger wing-coverts 
have pale rusty-brown edges, and the upper surface is paler. 
Wing and tail 3 or 4 mm. shorter. 
Mr. C. B. Horsbrugh exhibited a series of photographs 
of nests and eggs taken on the Smolen Islands and in the
