Da Costa received it from Wilts, Hants, and Lin- 
colnshire. Dr. Pulteney says it is common in Dorset- 
shire, in woods, among ‘moss, and in wet and shady 
places. We have found it in abundance in wet mea- 
dows, at Spetisbury, in that county. It has been found 
also by Mr. Montagu, about Tremough-House, near 
Penryn, Cornwall; and sparingly in Devonshire and 
Wiltshire. It is certainly a local species.

Gmelin has described a dient. shell as H. radiata ; 
ours is probably his H. rotundata; but we have retained. 
the trivial name given to it by Da Costa, in justice to 
him as the first describer, and hegiuse it so well charac- 
terizes the species..
