Exhibits. 



By Mr. J. D. Dean : An interesting collection of marine shells, from Cheefoo, 

 China, which, although mainly beach shells, included some very fine examples of 

 Cance'laria spengleriana, Soletellina japonica, and others. 



By Mr. K. Hurlstone Jones : A fine series of European land shells, including 

 Helix aspersa varr. unicolor and sonata ; H. marmorata and var. alba ; H. lactea 

 and var. grisea, H.pisana, H. conspurcata, H. lens, H. apicina ; Hyalinia helvetica ; 

 Rumina decollata ; and H. acuta, from Gibraltar. Cionella reissi ; Helix conoidea, 

 II. lanuginosa, and varieties of H. pisana, H virgata, and H. lactea, from Alge- 

 ciras. Helix aspersa var. unicolor ; and varieties of H. nemoralis, from Arosa Bay. 

 Also a beautiful set of Helix hortensis, from Osmington, Dorset, shewing transitional 

 colour gradations between varr. incarnata, lilacina, olivacea, and lutea ; a sub- 

 scalariform specimen of H aspersa, and examples of ' repaired ' shells from Dorset ; 

 a scalariform H. virgata, from Upover, Dorset ; Limnaa peregra var. burnetii, 

 from Loch Skene, and what he believed to be the same variety from Lake Winder- 

 mere — but this may prove to be an intermediate form between the var. lacustris and 

 the true burnetii, which latter it resembles in the peculiar intortion of the spire, but 

 is more angled at the shoulder of the whorls. 



A large number of duplicates collected by Mr. Jones at Gibraltar and Algeciras 

 were distributed amongst the members present. 



By Mr. R. Standen : Vertigo alpestris Alder, from the Roughlee Valley, Pendle 

 Forest ; and a choice series, from the Gulf of California, of Erato vitellina, E. 

 columbella, Ptistularia pnstulata, Trivia pulla, T. radians, T. sanguinea, T. call- 

 fornica, and Pedicularia californica. 



By Mr. R. D. Darbishire : Pedicularia sicula and varieties, from the coralline 

 zone, Messina, and elsewhere in the Mediterranean.
