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 ! Broderip : also Reeve.
