GENUS FICOPSIS CONRAD 



FICOPSIS REMONDII (Gabb) var. CRESCENTENSIS n. var. 

 Plate XI, Figure 14 



Description. Shell medium in size, fusiform and slender; spire low; whorls 

 four and angulated at the middle ; body whorl tri-carinated ; canal long ; aperture 

 wide and elongate; surface ornamented with delicate longitudinal ribs which are 

 crossed by spiral ribs of the same size and character which give the shell a 

 cancellated sculpture. 



This form has the same type of cancellated ornamentation as Ficopsis re- 

 mondii Gabb as well as a similar shape and character of the aperture. It differs 

 from F. remondii in the pronounced tri-carination of the body whorl. Gabb 

 mentions that on some specimens of F. remondii three faint angles may be seen. 

 F. crescentensis has that character definitely developed.
