emboldens me to refer them to the genus in question, for little 

 more than resemblance can be made of them. L. gigantea is a 

 large conical species with the height and breadth equal, the 

 whorls overlapping, and the sides in general straight. In the 

 present instance, merely internal casts, the whorls were very 

 slightly convex and did not overlap ; no signs of the band or 

 sculpture remain. This slight convexity may not quite afford an 

 index to the true outline, for Stoliczka says of L. indica — " only 

 when the surface of the shell is worn off do they present a 

 continuous convex outline." 



I have not seen the base, the reference to Leptomafia being 

 made solely on the lateral resemblance to L. gigantea, L. 

 indica, etc.
