310 THE ZOOLOGIST. 



Kendall remarks (Jo urn. Conch., July, 1912) that variation in 

 colour exists to a certain degree, but does not seem so great as 

 in H. caperata, that it is strongly calcophilic, and also xerophilic, 

 occurring always on dry pastures, and that it is probably not a 

 "strong" species, as it seldom seems to be the dominant. 

 Lewes, 1908 (Rev. C. E.Y. Kendall) ; Ovingdean, near Brighton, 

 November, 1910, very fine specimens (Rev. C. E. Y. Kendall). 



Var. albicans, Kendall. — Near Brighton (Rev. C. E. Y. Kendall). 



H. barbara, Linne" (= Helix acuta, Miiller). — Recorded only 

 from the neighbourhood of Eastbourne and Hastings. Mr. Jenner 

 remarks that " this species is now lost to East Sussex, the ground 

 where it occurred at Eastbourne having been built upon [near 

 Mill Gap] . The form which occurred there was white, opaque, 

 and very large, some specimens reaching 18 mm. in length. I 

 have searched the coast of Sussex from Brighton to Rye, in 

 every likely place, without finding another locality for this shell, 

 and it seems most probable that this now extinct colony was 

 introduced " (' Journal Conch.,' vi., July, 1891). Mr. A. J. 

 Alletsee has recorded its occurrence at Ore, Hastings. 



H. cantiana, Montagu.— Generally distributed, excepting on 

 the Vectian sands about Blackdown. 



Var. rubescens, Moquin-Tandon. — Near Lewes (J. H. A. 

 Jenner) ; Guestling (Hastings Phil. Soc.) ; Ore, Hastings (A. J. 

 Alletsee). 



Var. albida, Taylor. — Near Lewes (J. H. A. Jenner and C. H. 

 Morris). 



H. cartusiana, Miiller. (Plate III.) — Captain Thomas Brown 

 wrote (in 1844) : — " This species inhabits the chalk districts of 

 Sussex and Kent, among short grass, and is also common on the 

 coast between Dover and Brighton." Mrs. Merrifield remarked 

 in her ' List of the Land and Freshwater Shells of Brighton ' 

 (1864) that it is " particularly abundant on our chalk Downs 

 near the sea." Mr. Jenner says " it occurs on the chalk, rather 

 common, but very local" (as is indicated by the recorded stations 

 for it) ; he has taken large forms 15 mm. in diam. in several spots 

 near Lewes. Downs near Lewes in several places (J. H. A. 

 Jenner) ; Mailing Marsh, near Lewes (Ed. Collier, Journ. Conch, 

 xiii. 285) ; Lewes, on stunted grass near Mount Caburn, and on 

 Ranscombe Brow, verv local (W. C. Unwin) ; near East Dean on
