THE CONCHOLOGICAL SOCIETY, LEEDS. 



May.—yix. J. W. Taylor, F.L.S., in the 

 chair. 



A series of admirable drawings, illustrative 

 of the anatomy of the British slugs, made 

 by Mr. Charles Ashford, of Christchurch, 

 Kent, were shown. No papers were read, the 

 evening being devoted to the exhibition of 

 specimens, which were numerous and interest- 

 ing. Mr. John Ponsonby, F.Z.S., presented 

 a number of shells to the Society's 

 collection. The donations also included 

 Clausilia itala, from Lake Como, and Tes- 

 tacella haliotidea, from Aylsham, Norfolk, 

 given by the Rev. S. Spencer Pearce, M.A., 

 the last-named from Uxbridge, Middlesex, 

 given by Mr. C. H. Morris ; a couple of 

 thickened examples of Anodonia cygnea, 

 found in the Old Nidd stream, near Ripley, 

 by Mr. A. H. Pawson ; and a number of 

 shells sent by Mr. T. D. A Cockerel!, 

 which included various shells from Colorado, 

 New Caledonia, Petersfield, Hants, and 

 Poole, Dorsetshire, and examples of the 

 common Helix rotundata from the great 

 Skellig, off the coast of Kerry. The 

 general exhibits included nine species sent 

 by the Rev. T. Shankland, of Mold, Flint- 

 shire, as having hitherto not been recorded 

 for that county, viz., Vitrina, Helix aculeata, 

 H. /wftensis, H arbiistorum, H hispida^ 

 H. rupestris, Buii/nus ol'scurus, Balea, and 

 Azeca, which raises the Flintshire list to 35. 

 Helix venniailata was shown on behalf of 

 Mr. L. E. Adams as purporting to come 

 from Kent, but Mr. Adams considered the 

 evidence unsatisfactory. The Rev. H. 

 Milnes, of Winster, Derbyshire, sent some 

 fine examples of the varieties of Helix 

 arl'ustoruin from that place. — Yorkshire Post. 



MANCHESTER CONCHOLOGICAL SOCIETY. 



June nth. — Mr. Thos. Rogers in the chair. 

 Mr. R. Standen showed some living 

 specimens of Testacella scuiulum, taken in 

 Lancashire, and sent for exhibition by Mr. 

 W. H. Heathcote, of Preston. Mr. Heath- 

 cote, in an interesting note accompanying 

 the specimens, said that he was of opinion 

 that this slug may be much more common 

 than is generally supjiosed, as, owing to its 

 nocturnal and subterranean habits, it can 

 easily elude observation. Testacella was 

 noted as occurring at Crumpsall many years 

 ago by a Manchester naturalist, and the 

 late Mr. Edward Kirk, of Pendleton, also 

 observed it in a garden at Red Scar, near 

 Preston, in 1878, but subsequent searches 

 in these localities have failed to re-discover 

 it ; so that the recent authenticated find at 

 Forton makes a valuable addition to the 

 county list of Mollusca. 



Messrs. W. Moss and R. Cairns exhibited 

 a fine series of Unio pictoruin from the 

 canal at Marple, showing much variation in 

 form and colouring, most of them, instead 

 of the usual pearly nacreous interior, had 

 the inside of the valves a beautiful salmon 

 colour, which is very unusual. Unio tit- 

 ftiidus, Paludina vivipara, Pisidium amnicum, 

 A. anatina, A. cygnea, and a many other 

 species were obtained. 



Mr. Thomas Hey, of Derljy, exhibited 

 some living specimens of the very local 

 Achatina acicula, obtained by him a few 

 days previously in Monsal Dale ; also some 

 unusual forms of various species of Helix 

 from several localities in Derbyshire. 



Mr. Charles Oldham exhibited a collection 

 of about 100 species of Achatinella from 

 the Sandwich Islands ; also Helix nemoralis 

 from various places. 



Some unusual forms of Helix nemoralis 

 were shown from South Devon by Mr. L.
