XI.—On the Cambrian Faunas of Cape Breton and Newfoundland. 
By G. F. MATTHEW, M.A. 
(Read May 27, 1886.) 
In connection with his work on the St. John group, the writer has examined material 
from the Cambrian Rocks of Cape Breton and Newfoundland. This material has proved 
to be of much interest in further extending, our knowledge of the distribution of the 
organisms of this early period, and a short notice of the species observed may therefore 
be acceptable. The chief points of interest in the remains from these more eastern local- 
ities are, the very full representation of the older or Paradoxides fauna in Newfoundland, 
and the presence of the later forms of the Olenus fauna in Cape Breton. 
Cape BRETON.—Through the kindness of Mr. J. F. Whiteaves of the Canadian Geo- 
logical Survey, I have had an opportunity of examining the collection of Cambrian fossils 
made in Cape Breton, by the Survey officers. Some of the fossils in these collections are 
too imperfect to be determinable, and others are of a kind that do not indicate any special 
horizon in the Cambrian, but there are several lots from Mira River which are of greater 
value in this respect. The fossils found here belong to the upper part of the Olenus 
division of the Cambrian system; and the species observed were the following :— 
Peltura scarabeoides, Wahl. 
Sphærophthalmus alatus, Boeck. 
Agnostus pisiformis, Linn. 
There is also a small Lingulella, similar to one which characterizes the upper meas- 
ures of the St. John group, and is allied to Lingulella ferruginea, Salt.; and also an Orthis, 
too imperfect for determination, but which appears to be similar to O. lenticularis, Dalm. 
NEWFOUNDLAND.—Mr. J. P. Howley of the Geological Survey of Newfoundland sent 
to the writer, in 1885, a small collection of Cambrian fossils from several localities in the 
peninsula of Avalon. With the aid of these and the description of a number of species 
from Newfoundland, made some years ago by the late Mr. E. Billings and by Mr. J. F. 
Whiteaves, the writer has been able to classify imperfectly the Cambrian horizons existing 
in that island. 
There are beds of Cambrian age on the Straits of Belleisle at the northern extremity of 
Newfoundland, but these are separated from those of the peninsula of Avalon by a wide 
interval of Pre-Cambrian rocks; and their fauna resembles that of the interior continental 
areas of Cambrian rocks: it is therefore not thought necessary to refer to them further in 
this paper.
