There are, however, some species about which the writers are very- 

 doubtful, and which may eventually have to be dropped. 



Appended to this report is the Ottawa list of land and freshwater 

 mollusca as it at present stands. 



References are added to the pages in the Transactions on which the 



species are recorded or referred to, and a ? is prefixed to all names that 



are still in any way doubtful.
