expressed have not been removed by the Quilchena material which is altogether too imperfect 

 for that purpose. 



Sir William Dawson's specimen from Stanley park, Vancouver, was derived from beds 

 of Eocene age, but four other specimens enumerated by Knowlton are from the Cretaceous. 



Equisetum sp. 



Bib : Trans, R. S. C, IV., 188G, iv, 19-34. 



A specimen of Equisetum from the Lignite Tertiary of Porcupine creek and Great valley 

 shows in one case fragments of stems and in another remains of roots and tubers. These 

 are treated separately by Sir William Dawson altliough he considers there is reason to 

 think they may be the same species, 



Equisetum. arcttcum., Heer.

 Spitzbergen, 1870, 31, 



In collections from the Eocene formation of Red Deer river, obtained in 1898, there 

 were a (ew specimens of Equisetum arcficum. What is also probably the same species was 

 obtained from the Lignite Tertiary of Porcupine creek and Great valle^^ and recorded by 

 Sir AYilliam Dawson in 1886, but there is no further record of it in sul)ser|uent collections. 



E. arcficum is a type common to the Miocene of Spitzbergen, and its resemblance to 

 E. loyomivgense, Lesq,, from the Tertiary of Green River station, Wyoming, should be noted.
