Devonian. Across the bay in the peninsula of Gaspé numerous De- 
vonian sediments both of marine and estuarine origin are well developed. 
At Indian Cove, Gaspé, Tar point, along the Dartmouth river, near Cape 
Haldimand, at Long cove, Red Head, also at Grande Grève, limestones 
and sandstones belonging to the base of this System have been described 
by Sir Wm. Logan, and their entombed fauna and flora studied by the 
late Mr. Billings and Sir Wm. Dawson. 
There are other beds which may be called “ passage beds ” between 
the Silurian and the Devonian, At Scauminac bay, an interesting 
series of greenish-gray sandstone (Scauminac formation) occurs holding 
remains of Bothriolepis and Archeopteris which are placed at the sum- 
mit of the Devonian, a probable equivalent to part of the Catskill of New 
York, as pointed out by Sir William Dawson, and other geologists. 
The Laurentian Highlands.—Within the Hudson Bay basin, Dr. Bell 
has recognized bituminous limestones and shales belonging to the 
Devonian along the Abitibi river. In some places the limestone con- 
tains free petroleum. On Moose river, on the Missinaibi, Devonian 
rocks, probably equivalent to the Corniferous of Ontario are found. On 
Rainy island and Lowasky island between the cliff and innumerable 
islands along the Attawapishkat river, also on the Albany river and 
Kenogami river, Devonian limestones, some of which appear to be the 
equivalent to the Hamilton formation of Ontario, have been recorded 
by Dr. Bell, and the fossils described by Dr. Whiteaves. Mr. Low 
also records Devonian limestones from a branch of the Severn river. 
The Lawrencian Lowlands.—In the province of Quebec only a few 
isolated patches or outliers of Devonian occur. On the Famine river, 
coralline limestones occur of Eo-Devonian age, also on the Etchemin 
river, and in the Lake Memphremagog basin, where a Cauda-Calli 
horizon recently noticed by the .writer, 1894, occurs, associated with 
coralline and shaly limestones referred by Sir Wm. Logan to the Devonian 
system. The presence of occasional pieces of Devonian limestone 
in the volcanic conglomerates of St. Helen’s island, opposite Montreal, 
serves to indicate the former existence of Devonian limestone in that 
region, and points to a post-Devonian time in which Mount Royal was 
formed. In Ontario, the Silurian system characterized in its upper- 
most strata by beds of compact dolomite, are followed upward by the 
various members of the Devonian system which have an intimate rela- 
tion with those of the states of New York, Pennsylvania, and Ohio. 

1 The term Grande Grève formation, suggested by the writer some time ago, has 
been recently accepted by Prof. J. M. Clarke and Mr. Schuchert, whilst they suggest 
the terms St. Alban and Cape Bon Ami to include the beds numbered 1 and 2, and 
3, 4, 5, 6, respectively, in Billings’s Gaspé section. (Inserted on going to press).
