lines running along the back from the latter organ. The 

 sides and tail are white, the lower tentacles are very short, 

 appearing only as prominences.

 searched district. It is, perhaps, especially prolific on

 umbiUcata.

Dextral, not very minute ; whorls six or seven, not much 

 rounded ; peristome very thick, flatly reflected ; mouth with five

Shell small, oblong-cylindraceous, but distinctly tapering- 

 above, perforated, moderately strong for its size, obscurely 

 striolate, rather opaque, chocolate brown, with usually a
