cylindracea is found at Dolgelly, from which place a very fine specimen of Vitrea 

 rogersi approaching var. luiibilicata was also obtained. On the way to Fairbourne 

 a specimen of Helix aspersa was seen lying on a wall by the road ; this mollusc 

 had evidently been serving as a breakfast for some bird, as the animal was dead 

 and partially devoured. A visit to Harlech Castle produced Pyramidula rotiindata, 

 Vitrea nitidiila and V.- rogersi^ Javiinia cylindracea, Clatisilia bidenlata, Balea 

 perversa, Cochlicopa liibrica, and Vitrina pelliicida (dead). On the shore Natica 

 catena, Venus gallina, and TelUna balthica were found. The time, however, for 

 shore collecting was a very bad one. The slug which is chiefly in evidence in the 

 district is Arion ater, with several varieties, including one with a white sole, and 

 another with a similar white sole but with a bright yellow band dividing the same 

 from the black portion of the animal. A day at Aberystwyth included a few 

 minutes at the old castle, where Helicella virgata (type and yellow variety), and 

 H. caperata, Pyj-a7)iidula rupestris, faniinia cylindracea, Cochlicopa hibrica, and 

 Vallonia piilchella were found. The far-famed Mochras, or Shell-Island, north of 

 Barmouth, was also visited, with the customary poor results. Helix neinoralis 

 and H. aspersa are living amongst the thin vegetation with which the island is 

 clothed, but with the exception of some very fine coloured and banded varieties 

 of Littorina rudis and large Monodonta crassa found living on the rocks, together 

 with Littorina littoixa and Z. obfusata, and Patella vulgata, marine collecting is 

 at a discount. Amongst the fragments of thousands of common bivalves and 

 univalves with which the shore is covered were to be found dead specimens of 

 Gibbula viagits, Nassa incrassata, N. reticulata, Hcedropleura costata, Phasianella 

 pullus, Bittinm reticiilatum. Trivia europcea, Scala clathrus, Actceon tornatilis, 

 Natica catena, etc. — C. H. Moore (Read before the Society, December nth, 1907). 



Helicella cantiana (Mont.) in Shropshire. — I have to record the occurrence 

 oi H. cantiana on waste ground not far from Buildwas Station, Salop. Specimens 

 did not abound, indeed, the species was most local here, single examples being found 

 on the wild yellow Melilotus {M. officinalis) and Mignonette {Reseda luted). It may 

 very possibly be an introduction; since certain alien plants occur in the immediate 

 neighbourhood, but if I visit the locality, as I hope, this ensuing summer, I will 

 notice the environment more particularly. It is, at all events, an interesting new 

 record for a county that is none too well worked as regards mollusca. — J. Cosmo 

 Melvill {Read before the Society, March loth, 1909). 



Jaminia cylindracea m. sinistrorsum. — I am not aware that this monstrosity 

 has ever been recorded, but my collection contains an example which was taken by 

 Mr. J. T. Marshall in his garden at Torquay. It is not quite mature and lacks 

 the thickening round the lip. — J. R. le B. Tomi.in {Read before the Society, 

 March lolh, 1909).
