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 I 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.
