394 _ Descriptions of two 
revolve within the shell, terminating abruptly on the 
columella. Usually but one of them is apparent. 
When both are visible, their parallel and curved lines 
bear some resemblance to the track of a railroad. 
The oblique striæ on the whorls are very conspicu- 
ous. It varies much in the height of the spire, some 
specimens being very much flattened, others witha 
pointed apex ; usually the spire is high and rounded 
at the apex. . The aperture is moderate, not dilated, 
and often delicately roseate. Found in forests in 
the interstices of decaying logs, and under the E^ 
of wet and decomposing leaves.
