On the occurrence of Vertigo pusilla Miill. in Cheshire. — Quite recently 

 I have had my attention called to the "Report of the Manchester Scientific 

 Students' Association" for 1864 (pubHshed 1865), wherein, at page 15, in an 

 account of an excursion to Marple, Cheshire, on August 20 Ih, 1864, mention is 

 made of a number of shells taken on the aqueduct, and amongst these Verti_<^o 

 pusilla is included. For some reason, however, this locality for V. pusilla is 

 omitted in Hardy's "Synonymic List of British Mollusca," published further on 

 as an appendix to this Report (pp. 30-52). In the account of the ramble the late 

 Mr. John Hardy is stated to have given an address on the plants and shells 

 collected, and as he was a keen conchologist, it occurred to me that he had 

 probably been the finder of the Vertigo, and the specimen or specimens still 

 existed in his collection. Accordingly I made enquiries, and found that his son, 

 Mr. J. Ray Hardy, has in his possession the local portion of his father's land and 

 freshwater shells, and on my requesting him to look he not only found two of the 

 specimens taken on the above occasion, but also came across another he had 

 himself got at Marple in i860, when shaking moss for Coleoptera in the wood 

 between the old mill and the aqueduct. He also informs me that the late Mr. 

 James Walkden obtained four specimens from the base of the aqueduct ; these 

 are, or should be, in Vernon Park Museum, Stockport, where Mr. Walkden's 

 collection went after his death. The locality where these specimens were taken 

 is now practically destroyed ; the workmen employed in the periodical cleansing 

 of the canal having for many years made a practice of tipping the sludge over the 

 parapet wall, thus spoiUng what was formerly a capital collecting ground. In 

 searching out these records I was reminded of an almost forgotten episode which 

 happened to Mr. Edward Collier and myself in May, 1899. 'We were collecting 

 shells at the historic locality near Marple Hall, where the late Mr. Thomas 

 Rogers first discovered Vitrea rogersi, when we turned up a single dead specimen 

 of V. pusilla. Unfortunately this was accidentally broken when corking the tube 

 into which it had been put, but not before we had had ample time to carefully 

 examine and verify it. All our efforts to obtain further examples, both at the 

 time and since, were unsuccessful. The incident was reported at a subsequent 

 meeting of the Manchester branch, but was never properly recorded, as it was 

 expected other specimens would be found during some of the many excursions 

 made by Manchester conchologists to this favourite hunting ground. As this has 

 not been done, I think it as well to get what records we have together, the 

 evidence in hand being quite sufficient to give V. pusilla a place in the Cheshire 

 list. — R. Standen {Read before the Society, November 14th, 1906).

 interest to the members of our Society. Those marked * are believed to be new 

 records: — Vitrina pellucida, * Hyalinia lucida, H. cellaria, H. helvetica, H. alliaria, 

 and var. viridula, H. nitidula, H. radiatula, H. pura, H. crystaliina, H. fulva;
