 The following specimens were exhibited : — 



Mr. E. A. Smith : Some marine shells from Port Alfred, Cape 

 Colony, including species new to the fauna, others of considerable 

 rarity or in better condition than specimens hitherto obtained. 

 Several specimens belonged to species described by Mr. Sowerby 

 during recent years. Also a specimen of Murex mxatilis with the 

 anterior rostrum of the shell passed through a hole in a valve of 

 Area similis, the two being connected or cemented together by the 

 valve of an oyster. 



Mr. G. B. Sowerby: Two remarkable specimens of Cyprcea from 

 the collection of Dr. Cox. One of these was a white variety of 

 Cyprcea mnbih'cata, which, if not unique, is at least extremely rare. 

 The other was a monstrosity, in which the apex formed a prominent 

 spiral. 



Mr. H. B. Preston : Living specimens of Acavus from Ceylon. The 

 colour of the animal was reddish brown, and was uninfluenced by 

 variation of the shell coloration. Also a series of Pecten Icetus, Gld., 

 from Japan, showing colour variation. 



Mr. F. G. Bridgman: Species of Oliva, including 0. angtilata, Lam., 

 0. Masaris, Duel., and 0. rufula, Duel.
