Lucapinella Pilsbry, Manual of Conchology, pt. 47, p. 179. 

 Issued December 16, 1890. — Clypidella and Fissurella, in part, of 

 authors. 



Fisswellidce with an oblong shell, not sunken in or covered by the 

 mantle, and about as long as the foot ; its apex subceutral, wholly 

 removed by a rather large oblong perforation, which is margined 

 within by an entire (not truncated) callus ; edge of shell blunt, scarcely 

 crenulated in adults except in front and behind; sculptured xvilh 

 scaly riblets ; front and side-margins level, posterior mar gin a little 

 elevated. Animal ivith a fleshy foot, much too large to be contained 

 in the shell; mantle-edge thickened, papillose on its lower edge and 

 having narrow processes extending up over the shell-edge ; tentacles 

 short, obtuse; foot surrounded by a row of epipodial papilUz ; dorsal 

 pore surrounded by papillar processes. 



The genus defined above differs from Fissurella s. s. and Clypi- 

 della in the much larger, fleshier foot ; from Fissurellidea, Megate- 

 bennus, Pupilltea and Lucapina in not having the shell at all im- 

 bedded in the mantle; and finally from Macroscldsma by the sub- 

 central fissure, short tentacles and possession of an epipodial row of
