276 THE ICE AGE IN CANADA. 



bed under the boulder-clay at Eolling river, Manitoba, 

 which are noticed in Professor Penhallow's paper. They 

 were accompanied with fresh-water shells of the following 

 species, determined by Mr. Whiteaves, F.G-.S., Palaeontolo- 

 gist to the Geological Survey of Canada : 



Lymnea catascopium?, variety with very short spire. 



Valvata tricarinata, and a keelless variety. 



Amnicola porata ? 



Planorhis parvits .? 



P. hicarinahcs. 



Fisidmm abditum. 



Sphcerium striatinuin. 



With these was the centrum of a vertebra of a small fish. 



Dr. G. M. Dawson has also found fragments of wood at 

 Skidegate, Queen Charlotte Islands, in boulder-clay, 

 associated with shells of Lcda, etc. 



As elsewhere stated, at Eiver Inhabitants, in Cape 

 Breton, there is an indurated peat with branches of 

 Taxus and remains of swamp plants heloio the boulder-clay. 



The whole of the above collections have been placed in 

 the hands of Prof, Penhallow, of McGill University, for 

 revision and determination, and his results have been 

 published in the Bulletin of the Geological Society of 

 America, Vol. I., to which reference may be made for 

 details. 



The whole number of Canadian species has thus been 

 raised to 33, as follows : — 



1. Asimina triloba, Dunal. Don River, Toronto (Townsend), 



2. Brasenia peltata, Pursh. Green's Creek nodules (Miller). 



3. Drosera rotundifolia, L. Green's Creek, Ottawa (J. W. Dawson).*
