JENNER : MOLLUSCA OF EAST SUSSEX. 363 



Colb. may now be added, both occurring in distinct 

 localities near Lewes. 



H. carthusiana var. alba Jenner. New variety. Shell, 

 pure milk-white ; mouth and rib, white. 



Mr. T. S. Hillman took a single specimen of this 

 very beautiful variety in 1889 near Lewes, and I met 

 with several specimens in a neighbouring locality in 1890. 



H. carthusiana var. major Jenner. New variety. Shell 

 much larger than the type, 15 mills, in diameter. Occurs 

 in several spots near Lewes. 



H. rufescens var. rubens Moq. Occurs not uncommonly 



near Lewes. 



H, virgata DaCosta. — The following varieties have now been 



found : — 

 Var. nigrescens Grat. Lewes. 

 Var. leucozona Taylor. Wilmington. 

 Var. hypozona Moq. Seaford and Alfriston. 

 Var. subalbida Poiret. Seaford, Newhaven, and several other 



localities. 

 Var. albicans Grat. — With the last variety. I have noticed 



that these two varieties usually occur together. 



Var. picta Jenner. New variety. Shell banded with rich 

 purple brown, the bands broken by white dashes and 

 spots, arranged in a radiate manner, usually with a white 

 band at the periphery. 



This very pretty variety occurs not uncommonly near 

 Rye, Sussex — large on the sand-hills, and smaller and 

 more highly coloured in the marshes near. 



Of var. alba I discovered a very large colony near Newhaven, 

 in 1888, and it appears to occur there every year in more 

 or less abundance. When alive the black body of the 

 animal shows through the translucent markings, so that 

 at a distance the shell resembles the ordinary form, except 

 for its greater whiteness. 



H. caperata Mont. — Vars. subscalaris Jeff., bizonalis
