Radnorshire Slugs. — Last year I had several consignments of slugs and 

 snails from Radnorshire, obtained for the purpose of filling up blanks in our know- 

 ledge of Welsh moUusca. From Mr. F. Hall, of Bank House, Pen-y-Bont, was 

 received a most valuable series, the interest of which was enhanced by the obser- 

 vations given in his letter. This included a small specimen of Testacella haliotidea, 

 a fine and very characteristic adult example of Limax viaxiimis var. ferussacii, an 

 equally fine one of var. punctata with the black spots few and far between, one 

 half-grown of var. fasciata of a rich warm shade of brown in the markings, and 

 several juvenile specimens of the typical var. sylvatica. Of Arion ater there were 

 but one or two very minute young examples of a palish brown colour, a few of 

 A. circuniso-ipttts, and numerous typical specimens of A. hoi-teitsis. The specimens 

 q{ Agrioliinax agiestis were numerous, and included one or two of var. nigra, and 

 one or two of var. brttnnea Taylor (which is the same as British collectors have 

 hitherto called var. tristis, but not the real tristis as originally described). The 

 other specimens were of the two main varieties, the immaculate var. pallida, and 

 the maculate var. reticulata (which is the correct name for the spotted form which 

 British malacologists have hitherto called sylvatiac, but which is not the true 

 sylvatica of Draparnaud). There were various shells included in this consignment. 

 A couple of examples of the fine Hyalinia liicida, some of H. nitidiila and H. 

 alliaria, one or two Helix hortensis var. lutea 12345, several oi Hygroinia hispida, 

 and of Pyrainidula rottindata, and one of Vitrina pelliicida, all of which have been 

 seen and confirmed by my friend Mr. John W. Taylor. Mr. Hall's letter states 

 that it is the smaller kinds of slugs that are the most destructive, fields being simply 

 covered with them. He mentioned, writing gth November, that he was unable 

 then to get the large black Ai'ion ater, which is common at Pen-y-Bont in the early 

 summer, but he supposed they are now apparently gone into winter quarters. He 

 writes that the large dark-grey shell-snails (meaning Helix aspersa) are absent from 

 that side of the county, and that the thrushes give a good account of the Helix 

 hortensis to feed their young, after breaking the shells on a stone. Regarding 

 Testacella, he mentions that they grow to a good size at Pen-y-Bont, but are scarce. 

 From Mr. L. McKarg, schoolmaster at New Radnor, I received a boxful collected 

 by the boys for me, mostly Agriolimax agrestis of the usual two main forms, pallida 

 and reticulata, but also including a var. brunnea, and one or two var. nigra. There 

 were several Arion hortensis, and what is not included in my other consignments, a 

 few Limax arboruin, typical and small in size. From Miss E. P. Tudge, of 

 Knighton, I received through the kind intervention of Mr. A. W. Weyman, of 

 Ludlow, a large number of examples of Agriolimax agrestis of the usual two main 

 varieties, pallida and reticulata, and an abundant supply of specimens of Helix 

 aspersa var. flanwiea ; and from a lady correspondent at Pen-y-Bont, who merely 

 signs her initials H.F.J., I received an abundance of the same forms oi A. agrestis 

 and several Arion ho7-tensis, the largest examples of which were somewhat paler 

 than the others, and all of them with the foot-soles deep yellow. Regarding the 

 Agriolimax agrestis, in all the consignments it is to be observed that they are all 

 very deeply coloured, and very few pale ones among them ; this intensity of colour- 

 ing being what is usually observed at this late period of the year. It was for the 

 purpose of being able to colour the map of this species for Great Britain a uniform 

 red that we needed these specimens, and it is a satisfaction to know that we have 

 now seen and authenticated the existence of this ubiquitous animal through all the 

 counties and vice-counties of Scotland, England, and Wales, without one single 

 exception. — W. Denison Roebuck {Read before the Leeds Branch, and before
