Exhibits : 



By Mr. J. Cosmo Melvill : Two specimens of Scalaria Jimbriolata from the 

 Persian Gulf, to illustrate his note ; also a very unusual monstrosity of Rlitra episco- 

 palis L., in which the whorls just below the sutures are extremely thickened, their 

 incrassation being perfectly regular, and giving the appearance of a projecting band 

 of ivory whiteness, free from the usual orange markings of the body whorls. The 

 shell thus looks scalariform. A very richly coloured and perfect normal form was 

 also shown for comparison. 



By Mr. A. G. Stubbs : A series of Physa hypnorum, P. fontinalis, Limnaa 

 peregra, L. palustris, Planorbis nautileus, and P. spirorbis, to illustrate his paper. 



By Miss G. M. Harrison : A small series of marine shells from the Cape of Good 

 Hope, collected by herself, including fine examples of Turbo cidaris, Liotia granu- 

 losa, Oxystele zonatus, Gibbula cicer, and G. multicolor. 



By Mr R. Standen : A small set of interesting marine shells, presented to the 

 Manchester Museum by Miss E. C. Wilson, who had herself collected them at 

 Grand Canary, amongst them being the specimen of Latirus armatus, dealt with in 

 Mr. Melvill's paper, Ranella scrobiculator, Patella aspera, Pecten corallinoides, 

 Gibbula candei, Trochits sauciata, T. tamsi, and Cardita fabula. 



By Mr. H. Bolton : The series of Anthracosia turgida and Tellinomya robusta, 

 from the Lancashire Coal Measures, contained in the Manchester Museum. 



Amalia gagates (Drap. ) in Northamptonshire. — Last June (1896) I came 

 upon a colony of the above species in a town garden in Northampton. The slug 

 has not yet been met with in the surrounding district, and it is possible that it has 

 been introduced at some time in plant mould. I may mention that this species, 

 though often found far afield, thrives particularly well in gardens. — Lionel E. 

 Adams, Northampton {Read before the Society, August 12th, 1896). 



Helix nemoralis monst. sinistrorsum in Lancashire. — On June 15th, 1897, 

 Mr. R. Wiggles worth, of Clay ton-le- Moors, took a fine living specimen of this 

 rare monstrosity in a lane leading to Low Moor, Clitheroe, and has since very 

 kindly presented the shell to me. It is a well-grown example, in the best possible 

 condition, of typical libellula with the three lower bands coalesced. Careful search 

 was made for others but without success, although normal examples were plentiful 

 enough. It is interesting to note that this is but the second instance on record 

 of the occurrence of reversed H. nemoralis in the County Palatine — the first being 

 recorded by me in this Journal, vol. 6, p. 175- — R- Standen {Read before the 

 Society, January 12th, 189S). 



New forms of Helix terrestris Penn. — During the mild weather of February 

 last (1897) I visited the colony of H. terrestris and found them feeding in numbers 

 on the blades of grass. Amongst them were several individuals with interrupted 

 bands, which presented a tesselated appearance, and one with the band widened 

 so as to cover the whole shell with the exception of the projecting ridges. These 

 two forms correspond to V. maculaia of H, virgata and V. fulva of II. caperata, 

 therefore I suggest these names for the similar forms of H. terrestris. I took 

 several B. obscurus with the above covered with chalk, which gave them the 

 appearance of being banded with white — C. E. Wright, Kettering, March 20th, 

 1897 {Read before the Society. July 14th, 1897).
