The Ottawa Naturalist. 



[January 



by Mr.W. Hag-gart, in shale at the top of No. 6 Pit, Wellino-ton 

 Colliery, Nanaimo. This specimen is now the property of the 

 Provincial Museum at Victoria, B.C., and has been forwarded to 

 the writer by Dr. C. F, Newcombe, of that city, for examination 

 and comparison. 



Judging^ by its external form and t>urface markings, this fossil 

 seems to be a specimen of a previously undescribed species of 

 Unio, that is quite distinct from U. Hubhardi and from any of the 

 Unionidce of the Cretaceous or Laramie rocks of North America. 

 The species may now be provisionally named and characterized as 

 follows : — 



UnIO NaNAIMOENSIS (Sp. NOV.)
