•J. F. WiiiTKAVKs — Notes on the Devonian formation of Manitoba 
and the N. W. Territories. 
^Ir. Whiteaves gave a short address in wliieli lie di.sciissed the 
rehitionship of tlie fauna of the Devoninn formation of iiortliern .Man- 
itoba witlithat of northern Europe. In .Manitoba tiie Stringoeephelus 
zone is remarkablj' clearly develoj)ed. and holds a rich fauna, 
whereas in the 3Iackenzi(^ River district, most of the fossils so far col- 
lected seem to be from the Cuboides zone. 
Hknrv .M. A.Aii — Notes on Cambrian fossils from the Selkirks 
and Rocky ^lonntain region of Canada. 
This paper was based niaiidy upon a collection of Lower and Middle 
Cambrian fossils made l>y the author in the summer of 1891. It con- 
tained notes on some eight species of Lower Cambrian (OleneHus 
zone) fossils from the gray, glossy and calcareous .schists and lime- 
stones of the entrance to the Selkirks. some two miles west of 
I >onald. British Columbia. The latter part of the pa])er dealt with 
tlie forms met with in the .Middle Cambrian of mount Ste|»hen in the 
Locky mountains, near Field. \\. C. where the terrane is Jiiglily fossil- 
iferous. L'pwards of twenty sjjecies have been recorded from this 
locality, many of which are very interesting and well-jirescrved. 
Hknrv M. Ami — On the Potsdam and Cahnferons terranes of the 
Ottawa Palaeozoic basin. 
The stratigraphical, lithological and jtala-ontological relations of 
the Potsdam and Calciferous terranes. as seen and known in the 
( )ttawa i'ahiozoic basin and elsewliere were discussed in this paper; 
also the reference of these two terranes to the Canibro-Silurian or 
Ordovician epoch instead of to the Cambrian epoch, inferred from the 
internal evidence.

their recognition. 
.1. I>. TvRREi.i, — Pleistocene phenomena in the region southeast 
and east of lake Athabasca, Canada. 
The paper was the result of an exploratinn conducted by tlie autlu)r 
for the Canadian (Geological Survey in tiie hitherto unexplored 
region lying southeast of .Athabasca lake and north of Churchill. 
The region is underhiin by Arch;tan gneisses, etc.. and j'alaozoic sand- 
stones, and has some strongly marked glacial features. The general 
course of the striation is south-soutli-westward, but towards the 
nortli it turns to the west down the great valley of Athabasca lake, 
while in the southern portion of the region it turns more directly 
southward towards the plains. The amount of true subglacial till 
a|)i)eared to be rather small, but great niniibers of higii drundins, 
running with the glacial stri;c. were found in the basin of Cree 
lake and vicinity, and along Black river and around Black lake. These 
would a]ipear to be formed from material frozen in the ice.aiid collected 
in ridges by currents in the glacier. liidges of stratified sand or 
kames were also noted. 
The watershed north of Caribou river was an extensive sandy 
plain about the level of some high terraces around Cree lake, and was 
probably formed when the waters rushed southward from a circum- 
glacial lake. Terraces were also recorded about a hundred feet 
above iilack lake, which is itself three hundred feet above lake 
.Vthabasca. .\t liabasca. Wollaston and free lakes lie almig tin- line 
■of contact of the J'alteazoic and .Vndiaan rocks.
