The above lists iiicludo, in all, about 240 species, dis- 

 tributed as follows :* 



I'lants 33

Tile whole of tlie marine species, with two or three 

 exceptions, may be affirmed to be living northern or 

 Arctic forms, Ijelonging, in the case of tlie marine species, 

 to moderate depths, or varying from the littoral zone to 

 say 100 fatlioms. The assemblage is identical with that 

 of the northern part of tlie gulf of St. Lawrence and 

 Labrador coast at present, and diHers merely in the 

 presence in the modern gulf of a few more southern forms, 

 especially in its southern part, where tlie fauna is of a 

 Now F^ngland type, whereas that of the Pleistocene 

 may be characterized as Labradorian, or at least as corres- 

 ponding to that part of the gulf of St. Lawrence now 

 invaded by the Labrador cold current. 



I would call attention in this connection to the number 

 of species recorded as recent on the evidence of my own 

 dredgings in the lower St. Lawrence at Metis, liiviere-du- 

 Loup, Murray bay, and Kainouraska. Li point of fact 

 neai-ly all the marine species of the Leda clay and Saxi- 

 cava sand are still living on tlie coasts opposite the points 

 where the fossils occur. It is to l)e observed, however, 

 that in the modern river and gulf they are associated with 



* Exclusive of a few fresh-water species mentioned in the text, and 

 of which I have not seen specimens.
