The absurdity of mistaking the head for the tail, in Sowerby's de-

Genus LUCAPINELLA Pilsbry, 1890. 



Lueapinella PILSBRY, Manual of Conchology, pt. 47, p. 179. 

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

 authors. 



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

 mantle, and about as long as the foot; its apex subcentral, 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 with 

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

 elevated. Animal with a fleslty 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 papillce ; 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 Fissurcllidea, Megate- 

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

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

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