INTRODUCTION. 
In 1913, Schofield first noticed the presence near Elko, British 
Columbia, of fossils immediately superjacent to a great series 
of rocks (the Galton) generally assigned to the Pre-Cambrian. 
Together with Mr. Schofield the writer visited the locality during 
the latter part of the same field season and secured fossils from 
four closely related horizons in the basal layers of the Burton 
formation in the immediate vicinity of the Burton mine, about 2 
miles northwest of the town of Elko, British Columbia. 
Schofield has called attention to this discovery in a review 
of the Pre-Cambrian rocks of the northern Cordillera. 1 
In adjoining areas the Galton series is mantled by the De- 
vonian 2 , and Willis 3 found the Carboniferous resting unconform- 
ably upon a similar series of rocks in northern Montana, so that 
the importance of the discovery at Elko depended largely 
upon the age of the fossils. This is particularly true for the 
reason that the Pre-Cambrian age of the underlying beds has 
been called in question. 4 That the upper and best represented 
of the faunas secured by Schofield and myself should happen to
