In commenting upon this collection, Sir William Daw8on remarks that the plants of Bur- 

 rard inlet have a more modern aspect than those of the Nanaimo series or Upper Cretaceous. 

 On the other hand they are distinct from the Oligocene or Older Miocene of the Similkameen 

 and other parts of interior British Columbia. Between these they occupy an intermediate 

 position and correspond to the Laramie of the plains east of the Eocky mountains. They 

 thus also agree with the Atane beds of Greenland, the lignite series of the Mackenzie river 

 and similar beds in Alaska, a conclusion reached independently by Newberry on the basis of 

 the Puget group of "Washington. 



DESCiUPTION OF SPECIES. 



Acer sp.

The genus Acer, as represented by its fruits, appears to be very generally distributed 

 throughout the Tertiary areas of British Columbia. These fruits, nevertheless, vary greatly 

 in size, from which the inference may be drawn that there are several species common to the 

 region.

On the Tulameen river Lambe found fruits which were only 8 mm. long and 6 mm. 

 wide (Figure 2). These may be compared with and are probably the same as similar 

 fruits (Figure 1) derived from the Horsefly river and measuring 10 mm. long by 4 mm. 

 wide. Much larger fruits were also obtained from the Tulameen (Figure 3), and they are to 

 be distinguished not only by their greater proportions, but also by their distinctive shapes. 

 What seems to be a third species was obtained from the Horsefly river, and these seem to 

 be identical with fruits from Stump lake described by Sir William Dawson in 1890.
