Most of the transverse ridges are simple ridges only, over 

 which the spiral lines are continued without interruption. Occa- 

 sionally some one ridge appears to be a true varix. The species 

 has been regarded as intermediate between Turbinella and 

 Murex. It seems to be nearer to the former than to the latter 

 genus. 



Station. — In sandy mud, at a depth of from 6 to 12 fathoms ; 

 Cuming I Broderip : also Eeeve.
