A REVIEW OP TBE VOLUTIDAE 



small, with a single series of oblong, lat- 

 erally arcuate teeth, with three propor- 

 tionally large sharply angular cusps, which 

 are nearly equal; no side teeth. 



Except for the bulb-like protoconch 

 the shell might easily be taken for a spe- 

 cies of Heptunea (Roeding). The operculum 

 is similar to Fuslnus except that it is 

 smaller than the aperture. The description 

 of the soft parts here given was prepared 

 by Martin F. Woodward, then secretary of 

 the Malacological Society of London.
