 Shankland ; and a number of slugs from 

 various localities, by Mr. W. Denison 

 Roebuck, F.L.S. Examples of Hampshire 

 Succiiica;, sent by Mr. Charles Ashford, were 

 exhibited, who noted that tlie difficulty of 

 separating S. elegans from S. putris vanishes 

 on the examination of the animal, the 

 anatomical differences being very marked. 

 Mr. Taylor showed a number of shells, 

 which had been determined for him by 

 M. J. R. Bourguignat. 



October 7///.— Mr. J. W. Taylor, F.L.S., 

 in the chair. 



The exhibits were numerous, the most 

 interesting and important being that of 

 examples of Testauila sciituluin found at 

 Headingley, by Mr. Edgar R. Waite, F.L.S. 

 This exhibit was the more important inas- 

 much as these specimens are the first 

 Yorkshire examples whose specific identifi- 

 cation has been accurately placed on record. 

 The Society's referees have never been able 

 to obtain exam[)les of those known to occur 

 at Beverley and at Boston Spa, at all 

 events since our developed knowledge of 

 the specific differences of the animals of 

 this genus has made it possible to deter- 

 mine for certain whether they are to be 

 called T. scut 11 hi in or T. Iia Hot idea. Mr. O. 



I Marsden sliowed a slide of the lingual 

 ribbon of Arion ater. A fine living 

 example of Ainalia gagates var. rava, from 

 Crouch Hill, Middlesex, was shown on 

 behalf of Mr. G. K. Gude, and on behalf 



j of Mr. S. C. CockcriU examples of Paludina 

 contecta and P. vivipara from Mantua, 

 Northern Italy, with the remark that they 

 are found together in great plenty, and the 

 latter species nearly all as large as or larger 

 than the one sent, which was over 52 

 millimetres in length. A large number of 

 shells from Lamlash, Arran, and Dunblane, 

 Perthshire, were shown on behalf of Mr. 

 Alex. Shaw, of (Glasgow, several being new 

 records for the county from which they 

 came. A large number of new county 

 record shells from Flintshire, Carnarvonshire, 

 and Anglesea, sent by the Rev. Thomas 

 Shankland, of Mold, were exhibited, includ- 

 ing Plelix fnsca, H. pyginwa, Zonites glaber, 

 Planorbis a lb lis, PI. spirobis, PI. con tort us, 

 Physa liypnoruin, &c., from various localities 

 about Mold ; Ainalia carinata and Liinax 

 flavus, fiom Bangor ; Vertigo pygnuea, from 

 Great Orme's Head, and from Penmon 

 Point, Anglesea, &c., and a Welsh example 

 of Acme lineata, whose locality was not 

 stated, but of which rare (or rather seldom 

 seen) mollusc this makes the first record 

 fur the Principality. Several shells were also 

 shown on behalf of Mr. F. W. Frieke, of 

 Hull. These included Vertigo edentiila and 



I V. pygnuea, from Speeton Cliffs, and the 

 latter species also from Drenton Vale, and 

 some examj^les of Linincea peregra from the 

 Wolds at Riplingham, where it swarms in 

 the dirty coloured water of a cattle-pond 

 in which there is no vegetation or any 

 other shell whatever ; also examples of the 

 castaneous variety of Helix hortensis from 

 Cottingham, and of the hyalo/.onate and 

 roseolabiate variety of H. ncinoralis from 



I Burst wick, near Hull.
