Ohs. We have formerly received tliis shell from 

 Senegal, wherefore we at first supposed it might he 

 Lamarck's T. Senegalensis ; upon examination, how- 

 ever, it does not accord with his description. Our 

 shell is of a light hrown colour, the upper part of the 

 volutions ahove the impressed line are regularly 

 spotted with dark hrown; the spots on the lower 

 part of the volutions are arranged in rows, the upper 

 of which is contiguous to the impressed line. The 

 grooves of the upper volutions are interrupted by 

 the impressed line. In the larger specimens the 

 grooves become obsolete on the lower volutions.
