WELCH: ASSOCIATION OF H. XEMORALIS AND II. IIORTENSIS IN IRELAND. 303 



4. Kells, Co. Meath. — Old graveyard. Both species occur here, 

 though H. hortensis is not nearly so plentiful as at Ardbraccan. The 

 graveyard is larger but vegetation is not so rank, the grass is shorter 

 and there is less shade from trees. H. ne/)ioralis on the whole is more 

 plentiful here than H. hortensis. 



On the whole the species occur together in Ireland where the area 

 in which they live is restricted, and Helix hortensis thrives best in a 

 situation offering more moisture than the other seems to require, 

 either for feeding or aestivation during dry spells. 



In the Natural History Museum, Dublin, there are specimens of 

 H. Jiortensis from a few other Irish localities, which I have not visited 

 as yet. 



Surrey and Sussex East Records. — I liave pleasure in transmilting lu ihe 

 Society the following records in connection \\ith the authentication scheme. They 

 are based upon collections made during the years 1900 and 1901 by my young friend, 

 Mr. Russell Harrison, of Foulser Road, Upper Tooting, S.W. According to the 

 latest census list (Taylor and Roeliuck in Williams' " I^and and Freshwater Shells,"' 

 third edition) the five records are new for their respective vice-counties. Mr. Harri- 

 son wishes the accompanying voucher specimens to be laid before the Society, and 

 accepted for its Cabinet : — Sussex, East, v.c. 14, Helix lapicida L., Silverhill, near 

 Hastings, 1901 ; Surrey, v.c. 17, Unio tiDiiidus Phil., Bank of Thames, at Kew, 

 1900, Nerilina fliiviatilis L. , Bank of Thames, at Kew. 1900, Bytliinia leachii 

 Shepp. , Collier's Wood, near Merton, 1901, Planorbis nautiletis L., ditch in Rich- 

 mond' Park, 1900. — William Whitwell, F.L.S., Dec. 16, 1901 {Kead befoi e the 

 Society, March 19, 1902). 



Notes on the Miller's Dale Ramble, August 9th, 1902. — The chief attrac- 

 tion of tliis ramble was the taking of the small subterranean species, Cu-cilioidcs 

 acicnla. To Mr. T. Hey, of Derby, must be given the credit of first discovering 

 the locality of this interesting species (y. Conch., vol. 6. p. 122). The habitat is 

 the ovei"grown talus at the foot of a series of carboniferous limestone cliffs. Amongst 

 the larger masses of rock projecting from the surface, species such as Claitsilia per- 

 versa, Bicli/iiintts obscurtis, Pupa cylindracca, Caryckiuin miniiiiuiii. Helix 

 pnlcliella, H. riipestris, H. rotundata, H. kispida, J'it?-i/ia pellucida, and various 

 Hyalinice occur in abundance. Underneath the surface rocks is a deep layer of 

 disintegrated debris mixed with decayed vegetable matter, and it is amongst this 

 that the C. acicnla occur, Inirrowing to depths varying from six inches to a couple 

 of feet. Dead shells are numerous with about an equal proportion of living indi- 

 viduals, and a nice series may be obtained without much difliculty. A fairly 

 numerous colony of Helix hortensis was found, chiefly typical, with a few of the 

 shells showing coalescent bands. Typical examples of H. ntiiioralis were not found, 

 the prevalent forms being rubella and libellula with one band. H. arbusloniin and 

 its szxi'i.'Ci&s Jiavescens and cincta were extremely abundant, but very few H. lapicida 

 were observed. A Hon ater, Agrioliinax agrestis and A. Icevis were the only slugs 

 noted. — J. W. Jackson {.Read before the Society, Sept. loth, 1902).
