III . — The Occurrence of Helodont Teeth at Roche Miette and 
Vicinity , Alberta. 
By Lawrence M. Lambe. 
With the invertebrate fossils collected during the past summer 
by Mr. D. B. Dowling, of the Geological Survey, and his party, 
from the limestone bed at the summit of Roche Miette, Alberta, 
is a small, detached fish tooth which is of interest, 
Roche Miette is a noted landmark near Jasper lake, Atha- 
baska river, in the second range of the Rocky mountains, 30 
miles northeast of Yellowhead pass. The Grand Trunk Pacific 
railway passing to the north and west, touches the foot of 
this mountain, which rises to a height of about 7,700 feet above 
sea-level. 
Other small collections of invertebrate fossils were made 
by Mr. Dowling at a number of points on the north side of 
Athabaska river, in a general direction to the north of Roche 
Miette. One of these includes a second fish tooth which, with 
the Roche Miette specimen, form the subject of the following 
remarks. 
This other locality from which a fish tooth was obtained is 
on the eastern face of Bulirush mountain, near a small waterfall 
on a stream which runs through a deep ravine to Rrul6 lake. 
The fall is less than a mile from the lake, and is between 5 and 
6 miles from Roche Miette. 
According to Mr. Dowling the section studied by him in this 
area includes the lower part of the Cretaceous as its upper 
'ember, beneath which is a conformable series of limestones
