100 ON THE LAND AND FRESH-WATER 



Margaritana marginata, Say. With the foregoing, but not 

 very common. 



Margaritana undulata, Say. Common in the St. Lawrence down 

 to Quebec ; at which latter place it is very abundant, and often 

 beautifully coloured. 



Anodonta cataracta, Say. (A. fluviatilis, Lea.) Lake Calvaire, 

 near Quebec : abundant in small creeks near the St. Charles river 

 at Quebec : J. F. W. Large and plentiful at Brome Lake in 

 the Eastern Townships : R. J. F. Probably common in suitable 

 places throughout the district. 



Anodonta Lewisii, Lea. Lachine canal near Montreal. R. J. F. 



Anodonta Benedictensis, Lea. Mississquoi bay. Lake Champlain. 



Anodonta implicata, Say. Fine in the St. Lawrence near 

 Quebec : J. F. W. Berthier : R. B. 



Anodonta Ferussaciana, Lea. Creek at L'Orignal : R. B. 

 Fine in old stone quarries near the Mile-end toll-gate, Montreal. 



Anodonta undulata, Say. St. Charles river about three miles 

 from Quebec. 



Anodonta edentula, Say. Lake Matapedia : R. B. Brome 

 Lake in the Eastern Townships : R. J. F. I consider this species, 

 and perhaps even the next, as identical with A. undulata, 

 Say. 



Anodonta subcylindracea, Lea. Lachine Canal : R. J. F. St. 

 Lawrence at Quebec. J. F. W. 



Anodonta Footiana, Lea. Sixteen Island, Eagle Nest, and 

 Bevan's lakes. W. D. 



Anodonta modesta ? Lea. A few specimens which appear to me 

 to agree with Mr. Lea's figures and description of this species, 

 were taken by Mr. Bell from Lake St. John. 



CYCLADIDiE. 



The genus Cyclas was proposed by Bruguiere in the year 

 1792 ; but Scopoli's genus Sphoerium bears date 1777 ; and conse- 

 quently has priority, as has been shown by Dr. Gray. See Mr. 

 Temple Prime's elaborate monograph of the North and South 

 A.merican species in this genus, published in the *' Proceedings of 

 the Academy of Natural Sciences of Philadelphia" for December, 

 1861. 



Sphoerium sulcatum, Lamarck. (Cyclas similis, Say.) Metis 

 lakes, and a small lake six miles S.W. of Metis : R. B. Common
