The umbilical vibw (f. 37) certainly suggests this species rather than 

 H. caperata. 



In the British Isles the known range of this species is Kent, Sussex, 

 Hampshire, Surrey, Middlesex, Gloucester, Bucks., Herts., Suffolk, 

 Cambridge, Hunts., Northants, Leicester, Lincoln, Yorks., Pembroke 

 (Stelfox's list). To these can now be added Worcester (G. S. Tye, in 

 R.U.D. Coll.); Lancashire (R.S. Coll.); Cheshire (C. O., in Conch. 

 Soc. CoU.); Flintshire (J.W.J. Coll.); and North Berwick, Hadding- 

 tonshire (J. McMurtrie in Conch. Soc. Coll.). 



From this list it will be noticed that its known distribution at 

 present is more particularly south-eastern England with a few out- 

 lying counties further north and west which may ultimately be linked 

 up with the more southern ones. 



Helicella candidula (Studer) (non Michaud). — This species, 

 known to many collectors under the name of H. unifasciata Poiret, is 

 widely diffused on the continent, ranging through Germany, France, 

 Switzerland, Italy, Spanish Peninsula, etc. ; it is unknown, however, 

 in the north of Europe ; whilst in N. Africa it is said to be replaced 

 by H. reboudiana Bourg. 



It is a somewhat depressed shell, small in size, and minutely 

 striated ; umbilicus narrow ; whorls 42-5, slightly convex, suture deep : 

 aperture roundish-lunate, strongly labiate within. Size : diam. 7 — 10: 

 alt. 5 — 7 mm. The shell is whitish, sometimes unicolorous, and at 

 times variously banded with one or more brown bands, which may be 

 continuous or interrupted. 



A good deal of interest is attached to this species owing to its 

 having been recently reported fossil in this country by the Rev. 

 C. E. Y. Kendall, in his paper on the Pleistocene MoUusca found at 

 Woodston, North Huntingdonshire.^ 



In working through the large amount of material met with in this 

 interesting deposit, Mr. Kendall found a number of a small Helicella, 

 previously noticed in Britain (Barnwell and Crayford) as a Pleistocene 

 aberration of H. caperata Mont., but not hitherto recorded. After due 

 examination and comparison these shells were referred to H. candi- 

 dula Studer, var. alpicola Stabile. 



Having recently had an opportunity of studying some of the 

 Woodston examples (kindly lent by Mr. J. Davy Dean) and some 

 twenty specimens of exactly the same form from Ilford (presented by 

 the late Mr. R. D. Darbishire) alongside of authentic specimens of 

 H. candidula and its var. alpicola, together with the chief literature on 

 the subject, both French and German, I am reluctantly compelled to 

 disagree entirely with the above identification.
