Notes on the Lake St. John Country. 391 
a half miles. Among the specimens I collected here were 
the following :— 
Columnaria Alveolata. Murchisonia bicincta. 
Petraia. Murchisonia gracilis. 
Rhynconella. Murchisonia holopae. 
Maclurea Logani. Metoptoma erata. 
Straparollus (2) Bellerophon Argo. 
Pleurotomaria. Orthoceras. 
The most interesting however, was a large fossil some 
twelve inches long and eight inches in diameter, spheroidal 
in form, apparently consisting of a number of concentrically 
laminated masses, and somewhat resembling Stromatopora. 
It lay near the bank, and might have been washed up from 
the lake by the storms of winter, or had perhaps been left 
near its original position; its great weight, and hard im- 
perishable nature having resisted the forces by which the 
more perishable rock-bed was washed away. Sir William 
Dawson has come to the conclusion that this is a new 
species of Cryptozoon and has named it Cryptozoon boreale. 
It is probable that a description of this will be given by 
Sir William Dawson in a future number of the Record, 
The dip of the strata is toward the lake, At Point 
Bleu, the limestone has a rough crystalline form, is in 
layers from an inch to nearly a foot in thickness, and forms 
a cliff ten to twelve feet high. ‘The shore is strewn with 
large slabs, but weathered fossils do not appear as at 
toberval. At Snake Island towards the south-west of the 
lake, characteristic fossils of the Hudson River group are 
said to have been obtained, 
In a paper read in 1882 before the Royal Society of 
Canada, the Rev. Abbé Laflamme stated that he had found 
the Trenton limestone well developed upon the shore of the 
Saguenay River, from St. Anne to the upper side of the 
junction of the two discharges. He had also discovered 
some beds of the same south-east of the mouth of the 
Metabetchouan, reposing on the Laurentian, and showing 
signs of being the remains of larger deposits of which
