The Minutes of the Inst Scientific Meeting were confirmed. 



The Secretary exhibited a series of photographs taken in the 

 South Orkneys in 1908 by a correspondent of ' Tlie Times,' and 

 kindly sent him by the Editor of ' The Times.' The photographs 

 included views of scener}^ .and an interesting series of studies of 

 living Seals, such as the Sea-Leopard {Ste7iorhync]i,us leplonyx), 

 Weddell's Seal [Leptoni/ohotes ivedlelli), the White, or Oi'ab- 

 eating Seal (Lobodon carcinophagus), and Ross's Seal (Omniaio- 

 2)haga rossi). 



Mr. R. I. PoooCK, F.L.S., F.Z.S., exhibited a living specimen 

 of a Mole-Rat {Georychus) recently presented to the Society by 

 Capt. C. H. Armitage, who brought it fi-om Ashanti. Mr. Pocock 

 remarked that the animal possibl}' belonged to the species from 

 Togoland described by Matschie as G. zechi, and certainly repre- 

 sented a form never previously exhibited in the Gardens, 



Mr. R. H. Whitehouse, M.Sc, introduced by the Secretary, 

 gave an account of his Memoir on " The Caudal Fin of the 

 Teleostomi." The paper dealt with the structure of the caudal fin 

 in about fifty different species of fishes, mostly Teleostei, and 

 representative of nearly all the sub-groups. After each sub-group 

 a few general remai-ks wei'e added, and these were followed by a 

 short summary of results dealing with definitions and the taxo- 

 nomic value of the caudal fin.
