at Cliingford in Essex ; it interests itself in Arcliseology as 

 well as the various branches of Zoology and Botany, and 

 appears to have a flourishing list of active members. In the 

 present number of the Transactions is a pleasant account 

 of his visits to southern Spain by Mr. H. Kirke Swann, who 

 spent a fortnight in the spring of last year in a village in 

 the mountains west of Konda, where he was fortunate 

 enough to obtain the eggs of a good many Raptorial Birds, 

 including the Griffon and Egyptian Vultures. 



The other ornithological paper is a report on the birds of 

 Epping Forest, drawn up hj Mr. S. Austin, and contains 

 a list of 92 species which have been identified within the 

 Forest area. It is a remarkable fact that the Wryneck 

 should be so scarce a bird in Epping as to be almost 

 unknown. The number of nests in the Wanstead Heronry 

 has, we regret to leavn, decreased considerably of late 

 years ; there were only 58 nests in 1920 as against 72 

 in 1916.

The members of the Norfolk and Norwich Naturalists' 

 Society are certainly to be congratulated on the fare pro- 

 vided for them by Dr. Long, their Hon. Secretary and 

 Editor. The volume just received contains a good many 

 articles of vei'y considerable interest to ornithologists as 

 Avell as on other subjects. The annual address of the 

 President, Mr. B. B. Riviere, on his retirement, delivered 

 in April last, deals chiefly with the movement of Gulls along 

 the coasts of Norfolk. It is a phenomenon which has been 

 often noticed and commented on but never satisfactorily 

 explained, that every afternoon in late summer and autumn 

 there is a regular passage of Gulls in a north-westerly 

 direction along the coasts of Norfolk from the neighbour- 

 hood of Yarmouth to about Blakeney Point. The Gulls are 

 chiefly Great Black-backs and some Herrings. Mr. Riviei'e
