Bulletin of the British 
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. albicapilla. Wing 135-137 mm., tail 145-148. 
Sexes alike. This form is probably a representative of 
C . albicapilla. 
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, aud 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 
Sundal Valley in Northern Norway. An interesting series 
of the nests of Fringilla montifringilla and F. ccelebs from 
the latter locality was also shown. 
Mr. Scherren exhibited photographs of a young Cuckoo 
taken at two separate stages of its work of ejecting a young 
Titlark from a nest. Though the fact of such ejection has 
been well established, the photographs were of considerable 
interest as supplying incontrovertible evidence on the subject. 
The nest was found and watched by Mr. John Craig, a Scottish 
amateur naturalist, and the photographs were kindly sent by 
Mr. Peat Millar, of Beith, N.B., for exhibition. 
Dr. Bowdler Sharpe read a letter from Dr. J. von 
Madarasz and exhibited a specimen of the Pale Swift, Apus
