 Inhabits the Mediterranean. Lister. 

 This shell is smaller than L. anatifera, and may be readily 



known by its spinous serratures on the dorsal ridge. 



anatifera. 38. Shell compressed, somewhat trian- 

 gular, with five smooth valves seated on a 

 long peduncle.

 Inhabits the sea on the bottoms of ships and logs of wood ; not 



uncommon in Asia, Europe, Africa, or America. 

 The peduncle is sometimes a foot long, and the shell is gene- 

 rally larger than L. anserifera, which it much resembles ; it 

 differs in having the valves smooth, or only very faintly stri- 

 ated, the dorsal valve blunter on the edge, and the angular 

 points of the other valves more rounded. The curiously 

 grave assertion, that the animals which inhabit these shells be- 

 come converted by age into geese, may be seen in Gerard's 

 Herbal, page 1587. 



villosa. 39. Shell compressed with five smooth 

 valves, seated on a short downy peduncle.
