Cryptolopiia camerunensis, sp. n. 



Adult male. Nearly allied to C. herberti, Alex., from 

 Fernando Po, but the eyebrow-stripe and cheeks are dull 

 soiled white, and the throat is white slightly tinged with 

 rufous, whereas in the latter these parts are pale rust- 

 colour. 



Total length ca. 4'0 inches ; wing 2*1 ; tail 15 ; tarsus 0'7. 



Hub. Peak of Cameroon, 23rd April, 1909. 



Mr. Ogilvie-Grant remarked that Mr. Alexander's collec- 

 tion included examples of typical Alcippe monachus, Reich., 

 from Cameroon. These showed that Alcippe claudei (Alex.) 

 from Fernando Po was a distinct form, with the grey of the 

 head continued over the upper back ; in A. monachus the 

 grey extended only on to the upper mantle, and in A. abys- 

 sinicus (Riipp.) it was confined to the head and nape. 



Mr. P. F. Bunyard exhibited nests and eggs of the 

 following species : — 



Marsh-Warbler (Acrocephalus palustris). 



1. Five eggs, taken in Kent on June the 22nd, 1909, being 

 the second authenticated record for that county. 



2. A series showing normal types and varieties; also a 

 clutch of four eggs with an egg of the Cuckoo, taken in 

 Worcestershire on June the 25th, 1904. This was the second 

 recorded instance in Great Britain of this species being 

 used by the Cuckoo as a foster-parent. 



Heed-Warbler (Acrocephalus streperus). 



A series showing normal types and varieties, including a 

 curious clutch of abnormally shaped eggs with large blotches; 

 also a set of dark smoky green-coloured eggs. 



Two clutches of eggs of the Hedge-Sparrow (Accentor 

 moduluris) , each containing two eggs of the Cuckoo ; one had 

 five eggs of the foster-parent (cf. ' Zoologist/ x. p. 430). 



Seven eggs of the Cuckoo, six in clutches of eggs of the 

 Hedge-Sparrow, and the seventh with eggs of the Blackcap 

 (Sylvia airicapilla). The Cuckoo's eggs were very large,
