156 XEROPHILA VIRGATA. 
The specimens upon which Dr. Jeffreys founded the variety were found at 
Winfrith [erroneously spelt Wingfrith by Dr. Jeffreys] near Wareham, Dorset, by 
Mr. J. E. Daniels, of Epsom, about 1855, who, writing in Nov. 1875. says :—“ It is 
now upwards of twenty years since I found them. I should rather have called 
them ‘subearinate’; nevertheless, the keel was well marked, and the variety was 
entirely confined to one bank a few yards long.” 
BRITISH DISTRIBUTION. 
England—It has since been noted at Bratton St. Maur, Somerset, by Mr. E.W. 
Swanton ; at Yarmouth, Isle of Wight, by Mr. C. Ashford ; at Folkestone, Kent, 
by Mrs. Fitzgerald; at Eastbourne, Sussex, by the Rev. 8. Spencer Pearce ; at 
Thorpe, Norfolk, and Lowestoft and Mendlesham, Suffolk, by Mr. A. Mayfield ; 
at Islip, Oxon, by Mr. A. H. Jowett-Murray; in Yorkshire, at Bridlington, by 
Mr. W. E. Brady, at Pontefract, by Mr. J. Wilcock, and Bank-Field, Cottingley, 
by Mr. J. W. Carter. 
FOREIGN DISTRIBUTION. 
France—Mogquin-Tandon quotes the var. swhbearinata as living on the French 
and Corsican coasts, and especially cites Port Vendres in Pyrénées Orientales. 
Pascal cites var. swbcarinata from about Paris. 
The H. lineata var. I of de L’H6pital is cited for Ste Paix near Caen in the 
department of Calvados by its author. 
Italy—Var. carinata Pirona is recorded from Udine, Venetia, by its author. 
Algeria—The var. lineata-subcarinata Bourguignat is recorded from Bone and 
Oran by Bourguignat. 
VARIATION IN SCULPTURE OF SHELL. 
Var. striatula Bourguignat. 
Helix lineata var. striatula Bourguignat, Mal. Alger., 1864, vol. i, p. 220. 
SHELL with stronger and better-marked transverse strive, approaching certain 
varieties of Helix submeridionalis. 
It is not improbable that this form may, on a critical examination of its 
structure, prove to be a distinct species; it approximates to specimens named 
H. nilssoniana. 
BRITISH DISTRIBUTION. 
Sussex E.—A distinctly and regularly striate shell resembling Y. caperata 
found at Rye by the Rey. S. Spencer Pearce. 
France—Ax, Ariége, July 1887 ! Dr. W. E. Clarke.

FOREIGN DISTRIBUTION.

Helix variabilis var. D, Gassies, Moll. Agenais, 1849, p. 79. 
SHELL with the peristome greatly thickened by the extension and development 
of the submarginal rib, which may be white, rosy, or fawn-coloured. As subsidiary 
characters, it is noted that the shell is usually small and of an uniform whitish tint. 
The H. variabilis var. D of Gassies is described as ‘conical, white, peristome 
very thick.”
