96 TAYLOR : LIFE HISTORY OF HELIX ASPERSA. 



The Rev. J. McMurtrie writes : " At Moulin Houet Bay, 

 South Guernsey, the specimens are fine, very thin, and beauti- 

 fully marked, and abundant among furze in the open, but those 

 taken from the foot of a wall built with lime are not nearly so 

 thin. On a ruined cottage at Icart, amongst crumbled mortar, 

 the specimens are almost of usual soUdity. Lime is however 

 present in the soil everywhere, for where H. aspersa is thinnest 

 H. nevioralis is of usual thickness. Found also in the Island 

 of Herm : near the landing place, where there is no drifted 

 shell sand, the shells are very characteristic ; but behind the 

 shell beach, where the soil is largely mixed with drifted shell 

 sand, the shell is of nearly usual thickness. In Sark it is very 

 common and takes the place of the type, with which it is con- 

 nected by intermediate forms." 



This variety has been several times recorded for Yorkshire, 

 but without sufficient foundation. 



Has been found at Bastia, Corsica (Romagnoli). 



Var. zonata Moq.-Tandon. Shell pale yellowish or reddish with five narrow 

 spiral bands (=var. riifescens s.\. fasciatus Vicz.xd. — va.x. qitinque- 

 fasciata, Requien = var. /rtja'ate, Gassies). 



Mrs. Fitzgerald and Miss Fairbrass have kindly given me. 

 specimens from the Folkestone Chalk Hills. Miss F. M. Hele 

 informs me that she once found a shell at Cheddar, in Somer- 

 setshire, and the Rev. J. McMurtrie describes specimens from 

 Alnmouth, Northumberland, which would appear to be this 

 variety. 



Throughout France (Moquin-Tandon). M. Gassies records 

 it from the Agenais as \2cc. fasciata ; and M. Requien and others 

 have found it in Corsica at Bastia, Corte, Ajaccio, Bonifacio, 

 Vico, and Sartene. 



Var. undulata Moquin-Tandon. Shell smaller, thin, transparent, reddish, 

 with longitudinal undulatoiy wrinklings, brown and white (=var. 

 concolor pallida Shuttl.). 



Mr. James Abbot of Leeds has found a specimen of this 

 variety at Redcar, and Mr. Hudson of Middlesbrough has 

 ■collected some, though not characteristic, at the same place. 

 Mr. W. Cash has collected it at Longueville, Jersey, and the 

 Rev. J. McMurtrie at St. Heliers, in the same island. 

 Corsica (Blauner).
