The name " Kootanie series" was fiist used 1)\- l)i-. (ieoi'ge M. Dawson 

 in some notes furnislied by liini to his fathei-, Sii' WiUiain Dawson, in 

 ISSo, l)ased on held exploratit)ns made in 1SS4 in \\\v Rocky Mountain 

 region of All)erta, north of the forty-ninth jiai'allel. in tlu> conivse of which 

 collections were made from \aii()us lioi'izons, but then for the first time 

 from beds in the Lower Cretaceous, and it was to these beds that the 

 name was applied. The only fossils found in the Ijeds were remains of 

 plants, of which a considcM'able collection was made. These plants wei'e 

 determined h\ Sir William Dawson, and desciiptions and figuivs were 

 emijoched in a paper pi-esented by liim to the lioyal Society of Canada 

 on Mav 27, 1S85, in whicli \ver(> also contained the notes furnished by 

 Doctor Dawson." The principal locaHties foi- the plants were ^hll■tin 

 Brook, or Martin Creek; North Fork of Old Man River; near Canmore; 

 North Kootani(> Pass; entrance to Kootanie Pass; Coal Creek; and 

 Crows Nest Pass. Twenty-two forms are described. Kight of tlie.se 

 were new and the other 14 were identified with Lower Cretaceous and 

 Jurassic species previously known, a few of them occui'ring .also in Upper 

 Cretaceous beds. 



About the same time. Dr. J. S. Newl)erry made an exammation of 

 the Great Falls coal l)asin in Montana, but did not succeed in finchng 

 an.\' fossils l)y which its age coukl be determined. .\ little later, however, 

 Mr. R. S. Williams, a botanist living at Great I'alls, discovered impres- 

 sions of plants in a railroad cutting 5 miles abo\'e the mouth of Sun River, 

 which be sent to Doctor Newberry, who determined them and found 

 among them one of the new species described by Dawson in the paper 

 last mentioned, viz, the Zamitefi mnntnna Dn., also the Sc({U()ia SmittidHd 

 Heer, a Lower ('retaceous species from Greenland (Kome beds), which 

 was also found in the Kootanie and figured l)y Dawson.
