We have a single specimen from the shore-sands which is 

 probably referable to this species, and may possibly be the same 

 form as that referred to in Millett's list under the name Valvulina 

 triangularis d'Orbigny, Bulimine form. The aperture, however, 

 in our specimen is unfortunately broken.
