Var. devians Westerlund. 
Heltx ericetorum var. devians Westerlund, Nachbl. Deutsch. Mal. Ges., 1875, p. 72. 
The var. devians has the shell widely umbilicated, the last whorl expanded at 
the aperture, which bears a strong inner rib. Diam., ie 18 mill.; alt., 8 mill. 
BRITISH DISTRIBUTION.

at Clevedon, North Somerset. 
FOREIGN DISTRIBUTION. 
France—Var. devians is, according to Dr. Westerlund, found at Agen, Lot-et-

The var. minor Picard is deseribed as ‘shell half-size of type form, spire con- 
vex, and banding somewhat intense”; sub-var. minor Pfeiffer 
as 11 mill. diam. and 53 mill. alt. ; sub-var. minor Moquin 
as ‘‘much smaller than type, but of same form” ; sub-var. —a) 
minor Dum. & Mort. as 8-9 mill. diam. ; sub-var. minor : 
Bourg. as shell small, usually zoned, diam. 12-14 mill., Fic. 191.—2X. zta/a var.

diam, and 5-64 mill. alt. ; and sub-var. minor Caziot as iatagaa ches eS 
having 53 whorls and adiam. of 12 mill. and an alt. of 5 mill. i oe aa 
The sub-var. minor Germain is half the usual size, thin, yellowish-horn colour, 
with clear, fawn semi-transparent bands. 
The sub-var. intermedia Gassies is described as smaller than the type form, 
the smallest dimensions being given as 7 mill. diameter. The var. intermedia of 
Dum. et Mortillet (Moll. Savoie, p. 59) is a much larger form, varying from 11-14 
mill. in its smallest diameter. 
Sub-var. minima Kickx, from Brabant, Belgium, is probably the very small form. 
The sub-var. tardyi Bourguignat is characterized by the expansion of the 
umbiliens and of the termination of the last whorl. Diam: , Smill.; alt., 33 mill. 
The Helix ericetella Jousseaume is regarded as a var. minor of (tala by Drs. 
Baudon and Kobelt, but is considered distinet by M. Loeard and Dr. Germain. 
M. Locard saying it is distinguished from Y. itala by ‘its more depressed shape, 
especially towards the last w horl, its thinner shell, more regular coiling, narrower 
umbilicus, rounder aperture and reflected peristome.” 
This stunted and dwarfed form, which Moquin-Tandon and Dupuy regard as a 
northern variety, has been verified from very numerous localities in this country 
and abroad, and may probably be met with wherever the species is plentiful. The 
smallest specimens I have seen—about 8 mill. in diameter—were found by the Rev. 
S. Spencer Pearce at Wheatley, near Oxford, and are probably var. minima Kickx.
