Hah. Philippine Islands, &c. 



This species may be distinguished from the young of 

 the Mitra cucumerina, which might easily be mistaken for 

 it, by its strong keel-like transverse ridges.

 culd, laevigata ; cvnered, fusco hie illic variegatd et

ventricose, smooth; ash-colour, variegated and clouded

this monograph of the genus bears ample testimony.
