Only five of the species enumerated above are of value for stratigraphical purposes. Of 

 these none are found in the Miocene^ M^holly, vrhile there is an even distribution between 

 the Lower Eocene or Laramie and the Oligocene. If these latter be analysed more particu- 

 larly, it will be observed that there are three cases belonging to the Upper Eocene exclu- 

 sively, one to the Lower Miocene and one which is common to both. It therefore seems 

 probable, in view of this very strong tendency toward the Eocene, that the horizon is that of 

 the Lower Oligocene or Upper Eocene, and not higher. 



SIMILKAMEEN KIVER. 



The flora designated as Similkameen river is not from any one locality, but it represents 

 specimens taken from localities not otherwise designated, though within the Similkameen 

 valley. As here given it embraces 24 forms, and presumably includes localities such as 

 Similkameen, Tulameen, etc., etc., as well as the main stream itself. It should, therefore, 

 show a correspondence with the Similkameen flora as a whole.
