Art. LX.—On some remarkable Fossil Fishes from the Devo- 
nian Rocks of Scaumenac Bay, in the Province of Quebec; by 
J. F. Wurreaves. 
IMMEDIATELY after my paper on the Canadian adele G ll was 
written, Mr. A. H. Foord, of the Geological Survey of Canada, 
went down to the Baie des Chaleurs and spent fel LS and a 
half of the summer of 1880 in a careful and systematic examina- 
tion of the fish-bearing beds of the ees rocks of the north 
bank of the mouth of the Restigouche River. The exact locality 
at which the Pterichthys Ca nadensis was ‘uid is not the Baie 
des Chaleurs proper but Scaumenac eternal written Escu- 
minac) Bay, ce Neng Harbor, in the County of Bonaventure. 
n the shores of t ay a series of shales, sandstones and con- 
glomerates, now Entei to be of Devonian age, are overlaid, 
apparently unconformably, by the red sandstones and conglom- 
erates of the “ Bonaventure Formation 
From ‘ieee Tavduisi rocks Mr. Ford succeeded in obtaining 
a large and interesting collection of fossil fishes. Fully four-fifths 
nes. One of the specimens show s that the Canadian Pteric 
‘hve had two labial appendages or bar bels attached to the front 
margin of the head. These barbels are almost exactly similar in 
shape to those indicated by dotted lines in the ideal representation 
of the genus Pterichthys on Plate VI of the “Monographie des 
Poissons hg 4 du Vieux Grés Rouge,” which Agassiz claims to 
ne 
have seen in his P. latus, but in anadensis the barbels are 
very close togdelina at their nigh n two other specimens of a 
vialetta collected by Mr. o remarkable, flattened 
conical, dermal processes are plainly visible on the helmet, one on 
ilar to that of all the other plates, are half an inch long an 
lines and a half broad near their base. They taper gradually 
from their base to 9 obtuse point and are pressed close to the 
surface of the helm 
In addition to eae remains of Prerichthys, there are examples 
of eight or nine species of fossil ‘fishes in Mr. Foord’s collection, 
which belong to at least seven genera. "The f ollowing is a brief’ 
description of the most striking characters of six of these species,
