It is therefore clear that the general evidence points with force to the Eocene character 

 of Taxodium occidentale. 



The conclusion to be reached with respect to the age of the Blackwater beds is that 

 they are probably of Lower Eocene, but approaching very closely to the Upper Eocene as 

 represented by the Quesnel beds. 



KAMLOOPS. 



The very limited flora from the Kamloops beds was first studied by Sir "William Dawson, 

 and his results constitute the bulk of available evidence at the present moment. The recog- 

 nized forms are : — 



1 Carpolithes sp. Excluded. 



2 Castanea castaneoefolia. Oligocene, U. E. — L. M. 



3 Gomptonia diforme. Oligocene, L. M. 



4 Salix kamloopsiana. 



From this we at once exclude Carpolithes, while Salix kamloopsianaie of no present value 

 since it has been found at no other station. The two species remaining afford a very inade- 

 quate basis for conclusions, and these can only be presented tentatively. 



Castanea has already been found to be of Oligocene age. Gomptonia diforme is found in 

 only one other locality in Canada, which, according to accepted views, is to be regarded as 

 Lower Miocene. According to the latest revision of the genus by Berry^ this species is wholly 

 Tertiary, extending from the Eocene to the Miocene. It may be further remarked that 

 C. diforme is not comparable with C. matheronianum as Dawson supposed, but rather, as 

 Berry points out, with C partita, Lesq. from the Green River beds which are to be regarded 

 as Oligocene or Upper Eocene. 



The conclusion to be derived from this limited and very unsatisfactory evidence would 

 be that the Kamloops beds probably belong to the Oligocene, certainly not higher, possibly 

 lower.
