the same beds of a wood whicli lie referred to the same genus, but without specific deter- 

 mination. In 1888 he recorded what seemed to be the same species, at Nine-mile creek, 

 Similkameen river, and in 1885, similarly imperfect leaves, possibly of the same species, 

 were obtained from Burrard inlet, British Columbia.

This European, Miocene species is common to a large number of localises in the United 

 States, being found in the Fort Union group in the Bad Lands of Dakota ; the Livingston 

 beds of Bozeman, Montana ; the Denver group of Golden, Colorado and Carbon, Wyoming ; 

 the Laramie group of Black Buttes, Wyoming, and the Miocene of the John Day valley, 

 Oregon. 



In Canada, only two stations are at present known, the Mackenzie river and the 

 Quesnel river of British Columbia. 



Platanus aceroides f Goepp.

The determination of this species was made by Sir William Dawson in 1883, and is 

 open to question on account of the imperfect nature of the specimen, which was a piece of 

 wood. It was obtained from the Miocene of Bear river, Mackenzie basin, and was referred 

 provisionally to the above, since it seemed to correspond to the same species of wood as 

 determined by Schroeter. 



Platanus haydenii, Newb. 



Bib : Qeol. Surv. Can., VII, 1894, 36, 37 C. : Trans. R.S.C., IV, 1886 : Lat. Ex. Fl. 1868, 

 70; Cret. and Tert., Fl. 1883, pi. XIX, XX, XXI. 



This very well characterized species is recorded for the Fort Union group of the Yellow- 

 stone river, Montana ; the Denver group of Sedalia and Golden, Colorado, and the Laramie 

 group of Sand creek, Colorado. 



In Canada it was first recorded for the Tiignite Tertiary of Porcupine creek and Great 

 valley in 1886, and in 1894 it was observed in collections from the Omineca river, British 

 Columbia. 



Platanus heterophyllus, Newb. 

 Bib : Trans. E. S. C, I, 1882-88, iv, 32 : Brit. N. A. Bound. Com., 1875, App. A. 330. 



The above is recorded by Sir William Dawson as occurring at Wood End, as a loose 

 fragment, but probably from the Lignite Tertiary. It also occurs in the Fort Union group of 

 the United States.
