The South Australian shell is scarcely as transverse as 

 that figured, and is more crenulated at the margin, but Ber- 

 nard describes his as "margo ventralis crenatus,'' and this 

 character varies in our specimens, as do also the wideness and 

 roundness of the radial ribs. 



St. Paul Island, if that situated in the Atlantic is 

 referred to, is very distant; but no further than several other 

 accredited specimens extend.
