Montagu , pi. 30. f. 4. 
Shell oval, pale horn-color, with a purplish-brown tinge 
at the tip, which is most minute : spires eleven or twelve, 
flat, not regularly divided by a line of separation, but folding 
over each other and leaving the edge abrupt; the larger 
volution covering three-fourths of the shell, the others very 
small, the terminal ones suddenly and abruptly decreasing 
in size : aperture contracted, the outer-lip reaching ahore 
half-way up the shell; pillar-lip quite smooth, without fold 
or tooth, but the lower part of the outer-dip makes a short 
curl, enters the aperture, and becomes a strong ridge on 
the pillar, and by its flexure forms a sort of canal or gutter: 
length three-eighths of an inch - 9 breadth about half its 
length. 
Found in the Portland museum.
