 Einl. iii. p. 499. Gmelin, p. 3203. Wood's Conch, p. 14. 



Inhabits Asia, Europe, and America. Linnaus. 



It may be supposed from the general habitat which Linnaeus 

 has given, that he considered the present to be a commou 

 species, but his description is so very short, and his references 

 so very unsatisfactory, that no subsequent author has been 

 able to ascertain it. In Osbeck's Narrative to which he re- 

 fers, only two species of Chiton are mentioned, and in nei- 

 ther of these, nor in Seba's figure (which is quoted alone by 

 Schroeter without any mark of doubt) are the excavated dots 

 at all noticed.
