built in a plane-tree 28 feet from tlie ground. The par- 

 ticulars had already been recorded ( f British Birds/ iv. 

 p. 119, 1910). 



He added that last year a pair of Great Tits, possibly the 

 same pair, had laid in an old nest of a Greenfinch, about 

 8 feet from the ground. 



2. Two clutches of eggs and a nest of the Canarian form 

 of the Blackcap (Sylvia atricapilla) taken at Las Palmas, 

 Gran Canary, April 1906. The eggs were of the ordinary 

 type laid by that species. 



3. A series of eggs of the Roseate Tern [Sterna dougalli) 

 taken on the island of Kiunga, off the east coast of Africa, 

 in August 1906. This species, and also Lichtenstein's Tern 

 (S. albigena), breed there in countless thousands. The 

 series of eggs of the Roseate Tern was exhibited to show 

 that, on the whole, they were easily distinguishable from eggs 

 of the Common and Arctic Terns. As a rule, they were 

 somewhat longer and narrower than eggs of the two last- 

 named species, but not always ; the ground-colour was either 

 of a light buff or yellowish-stone colour, and the underlying 

 shell -markings were slaty or violet-blue, while the surface- 

 spots and markings were of a dark sepia-brown. 



Mr. H. G. Alexander made the following remarks on the 

 supposed occurrence of the Siberian Chiffchaff in Kent : — 



" On the 28th of November and subsequently, I have ob- 

 served a bird in West Kent which I believe to be a Siberian 

 Chiffchaff (Phylloscopus tristis) ; I have made no effort to 

 shoot it, as it seems to me more interesting to watch it and 

 see how long it will stay. 



" It looks very white below, with slight buff-grey markings 

 on the sides, particularly on the lower breast; above the 

 general colour is greyish-brown, with slight buff edges to 

 the quills ; the only real yellow is on the shoulder ; the 

 eye-stripe is fairly distinct in certain lights, chiefly behind 

 the eye, and the line through the eye is decidedly dark ; the 

 bill, eyes, and legs are very dark or black. 



" I have frequently heard it utter a single note, which is
