MOLLUSC A 371 



Only two specimens. It belongs to the group of L. exilis Gulick; is in- 

 conspicuously costulate below the suture, the sculpture gradually fading out, until the 

 last whorl hardly shews any marking beyond the lines of growth. There is a faint 

 spiral line just below the suture.
