“« Description of a new species of Amphipeplea,” by Dr. L. Pfeiffer. 
The shell I am describing belongs to the genus of freshwater 
shells distinguished by Nilsson from Limneus under the name of 
Amphipeplea, and sufficiently characterized by the shape and habits 
of its animal, perfectly agreeing with our new species, according to 
Mr. Cuming’s information, who first discovered it, and by whose 
name I am pleased to illustrate the species.
