Though the above lists of species are impei'fect, yet they seem to 

 afford .very satisfactory evidences that there are three distinct as- 

 semblages of marine invertebrates intermingled on the coast of 

 southern Labrador. We can easily separate from the list, as 

 foreign to this coast, three species of moluscs ; viz. Pandora' 

 trilineata, Natica heros, and Rissoa minuta. These shells, were 

 rare, and of small size, though on the coast of New England they 

 are large and abundant. 



By the aid of " The Invertebrata of Massachusetts," by Dr. 

 Gould, and a list of invertebrates found by Mr. Robert Bell, 

 Professor of Natural Sciences, in Queen's College, Kingston? 

 about the mouth of the St. Lawrence and the coast of New 

 Brunswick, published in the Canadian Naturalist and Geologist; 

 together with a list of the shells of Halifax by Mr. Willis, and 

 Stimpson's Invertebrates of Grand Manan, we are enabled to trace 

 the fauna peculiar to the coast from Cape Cod to Nova Scotia, as 

 it reappears again in the Eastern shores of the Gulf of St. 

 Lawrence, about Prince Edward's Island, at Gaspe, and extends 

 up the river St. Lawrence towards Quebec. 



Some of the following shells do not occur at Grand Manan, but 

 seem to be as abundant on the shores of Canada as in Maine:
