" 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 Limneeus 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.
