368 Mr. Gray's Monograph on the CT/prceidce, 



Col. Montagu observed that the animal differs in its young 

 state as much from the adult, as the shells themselves in their 

 young and adult states ; for the mantle does not cover the shell 

 when young, as it does when full grown. The mantle indeed is 

 not perfectly formed and coloured when the sh3ll is in the state 

 called by him C. bullata, 



Lamarck cites this species as being found fossil at Grignon, but 

 Defrance observes that he has never seen it there. There is a fossil 

 specimen in the British Museum, which appears very nearly re- 

 lated to this species, but is nearly twice as large.

 known by its small size, grooved back, and dull livid colour. It 

 has a white base, and is of the same colour when worn.
