Adams, Seneg. pi. 17. f. 12. Pirel. 



This shell, described by Adanson, is very thin and 

 brittle, but not transparent. It is externally marked 

 with about a hundred extremely fine grooves, which are 

 crossed by many ridges, giving the shell the appear- 

 ance of fine net- work. It is an inch broad, and rather 

 less in length. 



Inhabits the sandy shores of the island of Goree.
