 may indicate viviparity, not hitherto recorded in this species.

Test free, perforate, helicoid. Consisting of a double series of chambers, arranged 

 in a rapidly increasing spiral, the outer series being largely predominant and increas-

 thick, and showing as bands of clear shell-substance. The oral face of the 

 final chamber flat, containing the aperture, which is a well-marked cleft running 

 half-way across the septal face. 



Size (across oral face): — Length up to '80 mm. ; breadth up to "60 mm. ; 

 thickness up to '50 mm.
