This is a group of entirely problematic affinities, hut, in my 

 opinion, it does not belong to the Act<> <>,,i<1>i . The species are here 

 described because precedent has otuhlished this position for the 

 group. 



K. \\< i i I.ARIS A. Adams. 



Shell oblong, widely and profoundly umbilicated ; spire rather 

 raised, the apex obtuse ; pale brown ; whorls 3$, slightly convex (the 

 last ventricose), regularly cancellated. Aperture oval; inner lip 

 thin, simple; outer lip straight in the middle, angulated behind. 

 Length 3i mill. (Ad.').

K. SULCATA A. Adams. 



Shell oblong, thin, turbinate, deeply umbilicated ; spire elevated, 

 conoid; dull white; transversely sulcate, the sulci distant, inter- 

 stices longitudinally closely striated; whorls 3i, flat, angulated 

 above ; last whorl ventricose. Aperture oblong, anteriorly everted 

 and subeffuse; lip thin, angulated behind (.4^.).

Family TORNATINID^E Fischer. 



Shell spiral, cylindrical or fusiform, external, capable of contain- 

 ing the soft parts ; spire short or sunken and concealed, the apex 

 more or less turned over; aperture long and narrow, wider below ; 

 columella with a fold or simple; umbilicus none or very narrow. 

 Animal with the foot shorter than the shell, entire behind : head- 

 shield short, quadrangular, produced in two erected processes behind, 

 near the bases of which are the eyes. Radu la-teeth wanting; giz- 

 zard armed with three oval, tuberculate plates (See pi. 60). 



Thr-r -ii;iils differ from ^ijihundridcB in the shorter differently 

 shaped head-shield, the lack of epipodial (lateral) lol>cs and radula : 

 the differently shaped gi/xsml-platee, etc. They are unlike Art<m,,- 

 idce in wanting operculum and radula. 



Although the characters of the animal are so obvious and distinc- 

 tiv.-, it i- by no m. ans easy to classify many species known by theshell 

 alone, certain forms referred to Retusa being < -ly similar in
