Note on Graptolites from Dease River, B.C. 141 
Note ON GRAPTOLITES FROM DEASE RIVER, B.C. 
By Pror. CHartus Lapworts, F.R.S. 
In June, 1887, a small collection of Graptolites was ob- 
tained by Dr. G. M. Dawson on Dease River, in the extreme 
northern and inland portion of British Columbia, about lat, 
59° 45’, long. 129°. These fossils were derived from cer- 
tain dark-coloured, carbonaceous and often calcareous 
shales, which, in association with quartzites and other 
rocks, characterize a considerable area on the lower part of 
the Dease, as well as on the Liard River, above the conflu- 
ence. The collection referred to was transmitted by Mr. 
J. F. Whiteaves to Prof. Lapworth, whose special studies 
on Graptolites are well known. It is believed that the fol- 
lowing preliminary note by Prof. Lapworth will be of inte- 
rest, as the occurrence of Graptolites on the Dease River 
extends very far to the north-westward of our previous 
‘knowledge of the occurrence of these forms in North 
America. In 1886 a similar small collection was obtained 
by Mr. R. G. McConnell near the line of the Canadian Paci- 
fic Railway, in the Kicking Horse (Wapta) Pass. This 
and the new locality here described are the only ones 
which have yet been found to yield Graptolites in the entire 
western portion of the Dominion. 
Prof. Lapworth, under date December 13th, writes as 
follows :— 
I have, to-day, gone over the specimens of Graptolites, 
collected by Dr. Dawson, from the rocks of the Dease 
River, British Columbia. I find that they are identical 
with those examined by me from the rocks of the Kicking 
Horse Pass, some time last year. The species I notice in 
the Dease River collection are: 
Diplograptus euglyphus, Lapworth. 
Climacograptus comp: antiquus, Lapworth. 
Cryptograptus tricornis, Carruthers. 
Glossograptus ciliatus, Emmons. 
Didymograptus comp: sagittarius, Hall. 
New form, allied to Coenograptus.
