LAND AND FRESHWATER SHELLS IN NORMANDY. 



By SYDNEY C. COCKERELL, M.C.S. 



During the summer of the present year (1885) I paid a 

 short visit to Normandy, and though I was unable to devote 

 much time to collecting, I secured a fair number of species, 

 with two exceptions indigenous to the British isles. Most of 

 my observations were made at Veules-en-Caux, fifteen miles 

 west of Dieppe. The shore was unfavourable to marine 

 shells, and I only noticed a few littoral kinds such as Liltorina 

 rudis, Trochus umbilicatus, and Purpura lapillus. To judge 

 from the heaps of the last-named outside the cottages it would 

 appear that it is largely used as an article of diet. 



I append a full list of the land and freshwater species, 

 with localities and remarks : — 

 Sphserium corneum (L). — Rouen. 

 S. rivicoia (Leach). — River Seine, Rouen. 

 S. lacustre (Miill.). — Sotteville, near Veules, in the hardened 



mud of the ponds, which were all dried up owing to the 



excessive drought. 

 Pisidium pusillum (Gmelin). — Veules. 

 Paludina vivipara (L.). — Rouen. 

 Bythinia tentacuiata (L.). — Rouen. 

 Valvata piscinalis (Miill.). — Rouen. 

 Planorbis complanatus (L.). — Rouen.
