This is not near fo common a fhell,' though it is not 



unplentiful in fome parts, in large Hagnant pools, and 



flow rivers. We have found it of a fuperior fize in the 



the river Avon, in the north of WillJJiire: and is not un- 



. common in the Kennct in Berkjhire. 



Do61or PuLTENEY fpeaks of it as a Dorfcfjliire fhell; 

 but we never could find it either in that countv, De- 

 vonfnire, or Cornzoall ; where the H. peregra is very 

 common. 



Animal dull greenifh-yellow : head broad: tcntacula 

 broad, flat, conic, fpeckled with brighter yellow: eyes 

 placed on the head, at the bafe of the tentacula. Is ca- 

 pable of receding within its fhell as much as \\\e pere- 

 gra, and does not cover any part of it when in motions 

 lilce the glutinofa.
