362 JENNER : MOLLUSCA OF EAST SUSSEX. 



Limnsea peregra var. marginata Mich. — Taken by Mr. 

 C. H. Morris in an isolated pond on the Downs, near 

 Lewes. This curious form perhaps arises from excess of 

 calcareous matter in the water, as at times the pond is 

 thick with chalky mud brought down by the rains. 



L. palustris var. elongata Moq. — Occurs in the Winter- 

 bourne Stream, Lewes. 



L. truncatula var. minor Moq. — ^Taken near Lewes by Mr. 



Morris. 

 Helix aspersa Miill.— The following additional varieties have 



now occurred near Lewes, viz : — 



Var. conoidea Picard. 

 Var, globosa Moq. 

 Var. zonata Moq. 

 Var. undulata Moq. 

 Var. flammea Picard. 



A very large proportion of the Lewes specimens 

 approach either fla^nmea or undulata in colouring and are 

 generally very dark ; forms approaching grisea being rare. 

 In gardens in the town an especially dark race occurs, in 

 some cases being very nearly nigrescens Moq. At New- 

 haven, where I discovered a small colony of exalbida, I 

 found two specimens almost exactly intermediate in 

 colouring between that variety and an undulata form 

 which occurred with them. 



H. nemoralis var. hyalozonata Tayl. has occurred singly 

 at Lewes. A fine form of var. roseolabiata Taylor 

 occurs in one locality near Lewes, with band formulae 

 12345, 00300, and 00000. When living these shells have 

 a greenish tint from the body of the animal showing 

 through the pale yellow shell. They are certainly not 

 hybrids, but are in my opinion an approach to albinism. 



H. cantiana Mont. — Vars. rubescens Moq. and alba
