From a series of dredgings made at Whitsuntide I was fortunate enough 

 to receive two small bags of material. One, containing'washed dredgings taken 

 in 46 fathoms, 9 miles W. of Contrary Head, Isle of Man, appeared to the naked 

 eye to consist of dead bivalves and clean sand. Upon examination it yielded, 

 amongst other species, Odostomia scillce, Scrobicularia nitida, Lepton squamosum 

 et nitidum, Lima loscombii, hundreds of "live'' Rissoa soluta (rarely found in the 

 district except in a dead condition), and two minute shells which could not be 

 identified with any known British species. All the Gastropods recorded for the dis- 

 trict, of which it seemed possible for them to be the fry, were carefully examined, in 

 most cases the fry or very young shells being studied. As even then they could 

 not be named, it was deemed advisable to submit them to Canon A. M. Norman, 

 who kindly inspected them and informed me that they were examples of Cylostrema 

 millcpitmtatum, Friele, which had been procured during the Norwegian North 

 Atlantic Expedition at one station, viz., Stat. 192, Lat. 69° 46' N., Long. 

 1 6° 15' E., in 649 fathoms. The Manx shells were compared with one of Friele's 

 types which is in Canon Norman's collection, and were found to agree in all 

 points except size, their diameter being only one-fourth to one-third of that of the 

 Norwegian specimen. 



The shell is easily recognisable from our other British Cydostremata by the sub- 

 angulation of the under part of the whorls, and by the remarkable sculpture, 

 which consists of numerous spiral rows of extremely minute punctures. —

Note on Limnaea glabra. 



There is and has been for some years a general opinion amongst certain 

 Conchologists that this interesting speciesof Limnaa isslowlybut surely becoming 

 rarer in this country; it will, therefore, possibly be of interest to such to learn that 

 I have recently collected examples in two ditches at Hall Green, near Birmingham, 

 one of which I had previously searched. In the larger of the two ditches it was 

 plentiful and in company with Physa kypnorum and a few L. peregra. The 

 shells are mostly fine examples and in company with equally fine decollated 

 specimens.^ J am is Madison, Birmingham. 



The Slug Fauna of Lancashire. 



I have recently received from Knowsley near Liverpool, three consignments of 

 Slugs, which from their variety and number are of interest and, I think, worthy 

 of record. 



There were one hundred and seventy-five slugs in all, representing eleven 

 species and thirteen varieties. The list is as follows : — Avion empiricorum, Fer., 

 and vars. ruber, Moq., bicolor. Moq., bocagei, Simroth; A. subfusats, Drap. . and 

 var. griseus, Moq. ,< .. rtdt us, Cllge. ; A.fasciatus, Nils., and vars. flavesans, Cllge. , 

 griseus, Cllge. ; Testacella haliolidea, Cuvier; Limax maximus, L., and var. 

 marmoratus, Ckll.; L. marginatus, Mull , ( = Z. arborum, B. Ch.); L. variegatUSi 

 Drap., and var. rufescens, Moq.; Agriolimax agrestis, L. , and vars. griseus, Ckll., 

 nigra, Morelet; Am alia sowerbyi, Fer., and var. nigrescens, Ckll. — Walter E.
