Mountain : St. Anne : creek about two miles below Chat river : 

 Metis and Restigoucbe rivers : R. B. 



Limnoea elodes, Say. (L. palustris ? Linn.) Common every- 

 where throughout the district. Plaldeman in his monograph con- 

 siders it the L. fragilis of Linnaeus. In Europe L. fragilis is consider- 

 ed a variety of L. stagnalis, Linn., and the L. elodes of Say as 

 probably identical with the L. palustris. 



Limnoea catascopium, Say. A common species. As unpublished 

 localities, I may cite the St. Charles river near Quebec, and Cap 

 Rouge in the same neighborhood. Dr. Lewis of Mohawk (N.Y.) 

 considers it a variety of the preceding shell. 



Limnoea solida, Lea. (L. apicina, Lea : fide Haldeman.) Pro- 

 fusely abundant everywhere about the St. Lawrence at Quebec. 

 Metis, Rimouski, and White rivers : R. B. 



Limnoea caperata, Say. Widely distributed. Abundant with 

 Succinea ovalis, Say, on the banks of the St. Charles river, near 

 Quebec. Limngea umbilicata, Adams : is generally considered a 

 variety of this species. 



Limnoea humilis, Say. (L. modicellus, Say.) Green Island 

 village : Rimouski : St. Anne : R. B. Lake Calvaire near Quebec : 

 and ponds near the Mile-end toll-gate, Montreal : J. F. W. 

 L. parva, Lea, is supposed by Haldeman to be the young of this 

 Bpecies.

 Jide Haldeman.) Upper Lake Metis : Marl lake, Anticosti : (the var. 

 acuta) : R. B.
