By Mr. J. Ray Hardy : A remarkable form of Helicigona arbjistoritm — approxi- 

 mating in colour to the var. casfaiiea of Helix vevtoralis — collected early in the 

 present month in Prestwich Clough near Manchester ; it is interesting to find this 

 species still existing so near the city, as the larger Helices have practically been 

 killed off for a considerable distance round by the increase in thrushes and the 

 poisoning of the herbage by smoky rain. He also showed a fine series of HeliceUa 

 virgata of large size and great variety of marking, taken at Cleveleys near Plack- 

 pool, at the end of September last ; the species has considerably extended its range 

 along the coast between Blackpool and Fleetwood, since it was first observed near 

 Rossall about thirty years ago, and the specimens are now fully treble the size they 

 were then, and show far greater variation. 



By Mr. Edward Collier : Plaiiorbis vortex, P. contortiis, Heliiella caiiusiana, 

 and Valvata macrosloma Steenb.- — which has recently been added to the British 

 fauna — from Mailing Marsh ; P. itfitbi/icatiis, SegDiejitina nitida, and Bythinia 

 leachi from Pevensey Level. 



By Mrs. A. Gill : A series of Tapes, and other exotic bivalves. 



By Mr. J. W. Taylor : A number of portraits of past and present continental 

 conchologists.

 cleaned ; and Hyalinia hicida from Oldham Park Conservatory. 



By Mr. G. C. Spence : A large number of species of Urocoptis, including nepi- 

 onic tips of species oi Anoma, which are seldom seen in collections, owing to the 

 apical whorls being cast off as the shell grows ; an egg of Anoma sp., and many 

 beautifully prepared sections of the shells of various groups of the family. 



By Mr. Harry Allan : Pyrainiditla rotiindata, Hygromia giaimlata, Azeca 

 tridens, and var. crystalllna from Ilkley, Yorks. ; also an interesting series of 

 Clansilia bidentata var. cravenensis from Ilkley and Carle, showing difference in 

 form from each locality. 



By Mr. C. H. Moore : A collection of shells from Sulina, Roumania, including 

 very fine examples oi Limnaa stagtialis, L. pereger, L. faliistris, Bythinia tenta-

 etc. ; also a specimen oi Saxicava rugosa in situ in rock, from Tenby. 



By Mr. R. Standen : A series of British oysters from Whitstable, shewing 

 growth stages from the "spat" up to very old individuals of uncertain age, recently 

 presented to the Manchester Museum. 



By Mr. J. F. Musham : \ series of IMargaritana inargaritifera from Kirrie- 

 muir, N. B., remarkably thin and light in weight, though apparently full grown.

 8^ ins.) ; Comis pronietheiis (length 7 ins.) ; and Alelo athiopica (length ii| ins.), 

 from the shell collections at the Salford Borough Museum. In connection with the 

 last species, Mr. G. C. Spence reported having recently seen and examined an 

 example measuring over 16 inches in length in the Museum at Accj-ington, Lanes.
