PLEISTOCENE FOSSILS. 279 



SUMMAKY OF FOSSILS. 



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

 tributed as follows :* 



Plants 33 



Animals Protozoa, etc 21 



Echinodermata 7 



Mollusca 142 



Annulosa and Arthropoda 30 



Vertebrata 7 



240 



The whole of the marine species, with two or three 

 exceptions, may be affirmed to be living northern or 

 Arctic forms, belonging, in the case of the marine species, 

 to moderate depths, or varying from the littoral zone to 

 say 100 fathoms. The assemblage is identical with that 

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

 Labrador coast at present, and differs merely in the 

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

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

 New England 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, Riviere-du- 

 Loup, Murray bay, and Kamouraska. In point of fact 

 nearly all the marine species of the Leda clay and Saxi- 

 cava sand are still living on the coasts opposite the points 

 where the fossils occur. It is to be 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.
