Mr. Keeve's reference to Proc. Z. S., 1841, for Sowerby's 

 description is evidently a misprint for 1833 ; and the reference 

 to the same work, 1845, for C. rastrum seems erroneous. Mr. 

 Hanley 's reference to Keeve Conch. Syst. pi. 84 is also a 

 misprint for 74. 



Station. In sandy mud, at from 6 to 12 fathoms depth ; 

 Cuming! Sowerby.
