Mr. W. E. BuTTERFiELD exhibited an example of the 

 Mediterranean Shearwater, Pufflnus huhli kuhli, Boie, and 

 made the following remarks : — 



" The specimen now shown was picked up dead by a man 

 named Jenner, on the Pevensey beach, Sussex, on the 21st 

 February, 1906. It was carefully examined in the flesh 

 by myself, and its sodden and sandy condition left no 

 doubt that it had lain for two or three days where it was 

 found. On dissection it turned out to be a female. 



" This form is found in the Mediterranean, and is not 

 hitherto known to have visited the British Islands. 



'^'^For comparison I also show a specimen of P. kuhli 

 flaviTOstris (Grould), which replaces P. huhli huhli in the 

 Atlantic. The Mediterranean form differs from that of 

 the Atlantic, in having a smaller (especially shorter) bill ; 

 in having the basal portion of the inner webs of the longer 

 remiges less uniformly dusky ; and in having the front and 

 sides of the head somewhat lighter (cf. Hartert, ISTovi- 

 tates Zoologicse, xii., p. 97. 1905). The Great Shear- 

 water, Pufflnus gravis, 0'E.eilly, differs from both the 

 former in having a much smaller bill, a dark and well- 

 defined crown, sooty under tail-coverts, and sooty edges 

 to the feathers of the middle of the abdomen. 



" The Pevensey specimen may, I think, be safely assigned 

 to the Mediterranean form, and it furnishes a good illustra- 

 tion of one of the advantages of recognising sub-species, 

 namely, that thereby we are often enabled to point to a 

 more exact locality than would otherwise be possible." 



Mr. "WiTHERBY described an apparently new sub-species 

 of Dipper, as follows : — 



1. CiNCLUS CINCLUS PERSIC US, Subsp. U. 



Most like G. c.rufiventris, Tristram, from Palestine, but 

 larger, the wing of the male measuring 103-104 mm..
