INTRODUCTION 
GENERAL STATEMENT 
The present study is based upon collections of the Geological Survey 
of Canada made by J. R. Marshall, E. M. Kindle, J. F. Walker, and L. D. 
Burling. 
In 1922 Mr. Marshall collected Upper Ordovician fossils from the 
Kananaskis-Palliser map-area, Alberta, between Spray and Palliser 
rivers. One lot was from the lower western slope of mount Sir Douglas 
and mount Munro and the western slope of a knoll between, at an elevation 
of about 7,800 feet; and another lot was from the second creek north from 
Palliser pass, entering Spray river from the east. In 1923 collections 
were brought from localities in the immediate neighbourhood of Palliser 
pass. Mr. Kindle, in 1923, collected fossils from the same general horizon 
in Windermere district, B.C., at Sinclair springs, the lower end of Stoddart 
Creek gorge around the west base of the mountain for about 2 miles north, 
and from Fairmont Springs. There have been available for study small 
collections of Ordovician and Silurian fossils from Harrogate farther 
north. J. F. Walker in 1924 collected from the Upper Ordovician in 
several localities in the Stanford range, at Fairmont Springs, and near 
Columbia lake. L. D. Burling when a member of the Geological Survey, 
Canada, made a small collection in 1915 from Upper Ordovician beds, 
which he later designated as “Beaverfoot” beds, from the Beaverfoot 
range, northeast of McMurdo, near Golden, B.C. 
Among these collections of the Rocky Mountain Upper Ordovician 
there is a large proportion of forms quite distinct from those of the 
Upper Ordovician of central and eastern America, including new species 
and genera which are described in the following pages.
