 thickened, crenulated at the edge, and armed within with about 

 ten fine lirse, which run far within the aperture, but do not reach

This species belongs to the same genus as another form described 

 by myself as Pusus ? dbnormis. On further consideration I am of 

 opinion that they would be more correctly placed in the genus 

 Coralliophila. The present species is smaller and more coarsely 

 sculptured than G. abnormis from the Andamans.
