SEPTEMBER 29, 1899. ] 
the Devonian rocks of the Albany River at 
Old Fort Henley and of the Moose River, 
collected by the late Mr. George Barnston 
about 1834 or 1835, have been in the Mu- 
seum of the Canadian Survey, but nothing 
appears to have been published about them. 
In Keewatin a few fossils that are prob- 
ably of Devonian age were collected in 
1886 by Dr. R. Bell at two localities on 
the Attawapishkat River, and by Mr. Low 
from the Limestone Rapids on the Fawn 
branch of the Severn River. These fossils 
have not yet been critically studied, but 
among those from the last-mentioned lo- 
cality there is a recognizable fragment of 
Spherospongia tesselata, which is one of the 
most characteristic species of the Stringo- 
cephalus zone of the Manitoba Devonian. 
The existence of Devonian rocks on South- 
ampton Island has been quite recently in- 
ferred from the fact that a few fossils from 
that island lent to Dr. Bell by a missionary 
in 1898 are similar to those from the At- 
tawapishkat River. Dr. Bell had _ pre- 
viously stated that the limestone on South- 
ampton Island is ‘evidently exactly the 
same as that of Mansfield Island.’’* If this 
be the case the limestone of Mansfield 
Island may possibly be Devonian, rather 
than Cambro-Silurian as previously sup- 
posed.

RITORIES. 
The Devonian age of the limestones on 
Snake Island, Lake Winnipegosis, and 
Manitoba Island, in the lake of that name, 
was asserted by E. Billings in 1859, on the 
evidence of a few fossils collected therefrom 
in 1858. At that time Mr. Billings was 
under the impression that these limestones 
are, as he says, ‘most probably about the . 
age of the Hamilton group.’ In 1874 Dr.

J. W. Spencer collected some fossils, which 
Mr. Billings pronounced to be also of De- 
vonian age, from rocks on the islands and 
shore of Swan Lake and on the western 
shore of Dawson Bay, Lake Winnipegosis, 
Still more recently an almost exhaustive 
geological examination of the islands, shores 
and immediate vicinity of lakes Manitoba 
and Winnipegosis was made by Mr. J. B. 
Tyrrell in 1888 and 1889. Assisted by Mr. 
D. B. Dowling, Mr. Tyrrell also made an 
exceptionally large collection of the fossils 
of the Devonian rocks of this region. This 
collection, which has been reported on 
somewhat fully by the writer in two illus- 
trated papers published in 1891,* and 
1892,+ was found to consist of 133 species, 
but about nineteen of these could not then 
be determined specifically. Two addi- 
tional species of corals in this collection 
have since been determined, and an addi- 
tional species of pteropoda from a collection 
made later has been described, making the 
total of identified or described species now 
known from these rocks to be 117, as fol-

According to Mr. Tyrrell these fossils are 
exclusively from the Middle and Upper 
Devonian of the province, for the Lower 
Devonian has not yet been satisfactorily 
recognized in Manitoba, though it may be
