Horsefly River, where it occurs in beds holding leaves of the Similkameen 
group. The original specimens contained in the Similkameen collections 
were referred by me to P. elongata, Lesq., but both forms occur together 
at Horsefly River, and possibly they are varieties of one species. 
MISCELLANEOUS FRAGMENTS. 
The collections contain many fragments indicating the presence of 
additional genera and species. Some of them may belong to species of 
Acer, Aralia and Betula, and probably of other genera. The boring at 
Hastings, more especially, must have passed through some beds of shale 
exceptionally rich in well-preserved leaves. Should these beds ever be 
exposed by mining, they may be expected to yield a rich harvest of 
fossil plants. 
One bed at Burrard’s Inlet is crowded with roots of aquatic plants 
which resemble those found in the beds of the inland Laramie holding 
the leaves of Lemna scutata.' 

In summing up the results of this study of fossil plants from the 
Tertiary of southern British Columbia, it appears, from a comparison 
with the flora of the Upper Cretaceous Nanaimo series, that the Bur- 
rard’s Inlet species are distinct and of more modern aspect.” On the other 
hand, they are also distinct from those of the Oligocene or older Miocene 
deposits of the Similkameen district and other parts of the interior of 
British Columbia.* Between these they occupy an intermediate position ; 
in this respect corresponding with the Laramie of the interior plains east 
of the Rocky Mountains. They also resemble this formation in the 
general facies of the flora, which is not dissimilar from that of the Upper 
Laramie or Fort Union group. 
We may thus refer the plants now in question to the Paleocene or 
Eocene, and regard them as corresponding with those of the Atané- 
kerdluk beds in Greenland, the lignitic series of the McKenzie River, and 
the beds holding similar plants in Alaska. Thus, the opinion expressed 
in 1890, from the very small collection then available, was substantially 
correct ; and I find that the late Dr. Newberry had arrived at a similar 
conclusion from the study of the plants of the Puget group in Washing- 
ton Territory. 
This flora thus serves to fill up one of the gaps in our western series 
of fossil plants, namely, that between the Cretaceous and the Lower
