This species belongs to the same genus as another form described 

 by myself as Fusus ? abnormis. On further consideration I am of 

 opinion that they would be more correctly placed in the genus 

 Coralliopliila. The present species is smaller and more coarsely 

 sculptured than C. abnormis from the Andamans.
