excavation of the railway cuts, and must have come from horizons CG2 to 
CG11. The fossils of CGI 7 are from a single block of the same rock and 
from somewhere between CG3 and CG11. 
Another fossil locality is north of Blairmore on the lower part of a 
small creek which flows between Green hill and Bluff mountain, where 
blocks of the fossiliferous, hard, fine-grained, calcareous sandstone occur. 
These blocks are almost in situ and do not appear to have moved very far. 
They contain numerous fossils which are listed under CI1. 
Another section of the Fernie formation, with concealed parts, is 
exposed in the shale quarries south of the railway track at Blairmore. 
There, in drift between the two easternmost quarries, blocks of the fine- 
grained calcareous sandstone carry a small fauna listed under CJ2. In 
the western of the two eastern quarries, in dark shale, and at a level of 
about 400 feet above the base of the formation, Belemnites sp. was collected 
and is listed under CJ3. Higher in the section and in the “green” bed 
exposed in the brickyard quarry a few specimens were collected and are 
listed under CJ4. The collection made by Dr. W. F. Ferrier came from 
near the base of the shale quarries section 1 ; it is listed in the table under 
CJ1. 
The upper part of the Fernie formation is exposed on the north bank 
of Castle river from just below the Coal Securities cabins downstream to 
Hell Gate canyon. The green bed outcrops just below the cabins, is 
about 50 feet thick, and is overlain downstream by the thin-bedded sand- 
stones and shales of the passage beds; the fauna of this green bed is listed 
in the table under DC1. Downstream a number of folds keep the passage 
beds at about river-level for some distance. Finally, downstream, lower 
beds appear, first the green bed and beneath it grey and black shales. In 
these shales, at an horizon of about 270 feet below the green bed the upper 
Gryphaea bed occurs and at about 325 feet below the green bed the lower 
Gryphaea bed is found. The fossils of these two beds are listed under 
DD2 and DD1, respectively, in the table. 
FERNIE FAUNA 
In the table page 85 the entire known Fernie fauna of the Blairmore 
and South Fork or Castle River areas is listed and horizons and localities 
are given where possible. 
There are thus three faunas in the Fernie formation of the South 
Fork and Blairmore areas : 
Green bed fauna 
Corbula munda fauna 
Cklamys mcconnelli fauna 
Chlamys mcconnelli Fauna 
The Chlamys mcconnelli is the oldest of the local Fernie faunas. It is 
found only in the Lille member and the Lille member is known only in the 
valley between Bluff and Grassy mountains, where it outcrops on a small
