Remarks. The above-named localities prove this 
to be a widely-spread species. Its diminutive size 
has probably prevented its.being observed in other 
places. It offers but few varieties, and is easily 
distinguished by its conical form, and thin, amber- 
colored, transparent ‘shell: Sometimes the outer 
whorl.is slightly carinated. It is found under, and 
in the interstices of, wet decaying wood, wie — 
— ar — leaves in the forests.
