During the summer of 1915 remains of fishes and invertebrates 
were obtained by Geological Survey parties at two localities, about 
two miles apart, west of Banff, in rocks that have been regarded 
as of Jurassic age and coloured as such on the map? 
The fish remains represent three apparently undescribed species 
belonging to three distinct genera all of which have a considerable 
range in geological time. The fishes, therefore, in this particular 
case, throw little light on the exact age of the beds in question. From 
the invertebrates, however, more definite information is fortunately 
obtainable as they have been recognized as belonging to a fauna 
already known as distinctive of a lower Triassic horizon in the Rocky 
Mountains region of the United States. It appears necessary there- 
fore to regard the beds from which the above fossils were collected 
as most probably of lower Triassic rather than of Jurassic age. 
At the first of the above two localities, a railway cutting on the 
line of the Canadian Pacific railway a few hundred yards west of 
Massive (a station 13 miles west of Banff), Mr. L. D. Burling, of the 
Geological Survey, collected fish remains representing two species, 
with lamellibranchs, lingulæ, etc. At the secondslocality, two miles 
east of Castle Mountain railway station, on the trail to Johnson 
_ creek, at a point about two miles north of the forest ranger’s cabin, 
Mr. J. A. McLennan, field assistant to Dr. E. M. Kindle, of the 
Geological Survey, obtained a specimen of a third species of fish and | 
some invertebrates. . 
The fish bearing layers from both of these localities are of a very 
fine, dark grey, calcareous sandstone, with a brownish tinge on 
weathered surfaces. The beds exposed in the railway cutting at 
Massive have been referred to by Professor John A. Allan (Guide 
Book, No. 8, p. 191), as composed of shales of Jurassic age (Fernie 
shales). It would appear, therefore, that with these shales occur
