NOTES ON THE LAND AND FRESHWATER 

 MOLLUSCA OF EAST SUSSEX. 



By J. H. A. JENNER, F.E.S. 



(Read before the Conchological Society, April 8th, 1891). 



In 1884 I compiled a List of the Land and Freshwater Shells 

 of East Sussex, which showed the species then known to 

 inhabit the vice-county and formed a basis for future work. 

 Since that time some considerable attention has been devoted 

 to the subject by myself and by my friends, Messrs. T. S. 

 Hillman and C. H. Morris, and some interesting additions 

 — mostly among varieties—have been made. Our work has, 

 however, been chiefly confined to the Ouse drainage district, 

 and some portions of the county still requixe further investiga- 

 tion. Among the additions are the following : — 

 Paludina vivipara L. This was inadvertently omitted from 

 my list. It occurs in Pevensey Levels (vide 'Zoologist,' 

 Dec, 1885), but I have never yet seen Sussex specimens.
