10. BuLiMus? (Laoma) Leimonias. 



Shell trochiforni, polished, brown-spotted; spire coiiical, rather 

 higher than broad, apex obtuse ; whorls very slightly convex, polished, 

 with one or two slightly sunk lines on the front half ; last whorl with 

 a distinct rib-like keel on the front edge ; two spiral grooves on front 

 half outer side ; the side flattened with several small concentric grooves ; 

 axis minutely and deeply perforated ; mouth square ; peristome simple, 

 slightly reflexed near the axis ; the throat with three equal, well- 

 marked spiral ridges, one on the outer side of the posterior, and an- 

 other opposite to it on the outer side of the front lip, and one on the 

 middle of the right side or outer edge of the last whorl. Diam. yV*^ 

 of an inch. 



Hab. Auckland ; Major Greenwood. 



I am inclined to regard this shell as the type of a particular sub- 

 genus of shell which may be characterized by the simple peristome, 

 the perforated axis, the square mouth, and the spiral ridges in the 

 throat ; but 1 have only seen a single specimen, and it may be, though 

 I regard it as very improbable, the young state of a Pupa or Vertigo. 

 If it prove distinct, it may be called Laoma.
