where the latter series is well developed, whilst the lower division of the 
St. John group holding Protolenus and Paradoxides occurs at Hastings 
cove, along the Kennebecasis valley, and in St. John city itself. The 
middle division of the St. John group holding Lingulella is well 
developed in St. John city, and constitutes a formation consisting of dark 
and light gray slates and flags, with sandstones seven hundred and fifty 
feet in thickness. In the upper division of the St. John group, such 
as it is developed on Navy island and in St. John city, Dictyonema 
flabelliforme, and Peltura scarabæoides are the characteristic fossils of 
the gray sandstones and fine black shales of this upper series. The rocks 
of Hanford brook are highly fossiliferous and constitute the Hanford 
formation of Prof. C. D. Walcott. These are of same age, as the slates 
of Ratcliffs Mill stream, Caton’s Island, Porter’s Brook, etc. 
The limestones, etc., of Chapel Arm, Trinity bay, and at Manuels 
brook, in Newfoundland, correspond to the lower division of the St. John 
group as developed in New Brunswick. In Gloucester county, on the 
Tête à Gauche river, on the Nipisiguit river, near Landing Falls, on 
the Serpentine river, on the Miramichi river, in Northumberland Co., 
at Porter’s brook in St. John county in N.B., the Cambrian has been 
recognized by Dr. Ells, Dr. Matthew, and Prof. Bailey, and described by 
them. 
The Avalon, Random Sound and Signal Hill series of Newfound- 
land have been defined by Murray and Howley as well as by Prof. C. D. 
Walcott from that island and constitute part of the Cambrian system. 
South-east of the St. Lawrence-Appalachian dislocation in the pro- 
vince of Quebec, the Cambrian system has been recognized by Logan, 
Richardson, Ells, and other geologists, and includes the gold-bearing 
slates of the Chaudière valley and Beauce district, as well as the Sillery 
slates or “pillar” sandstones, which are held by some to be the 
equivalent of the Potsdam formation of New York state. Sillery slates, 
sandstones, and conglomerates occupy a wide belt in the province of 
Quebec south of the St. Lawrence. 
In the counties of Bonaventure, Gaspé, Rimouski, and Temiscouata, 
as well as in ‘Bellechasse and Lévis, the Sillery shales and quartzites, 
limestones and argillites, limestone-conglomerate and quartz-conglom- 
erate, slates and felspathic sandstones also occur, and many of them 
prove to be fossiliferous, as at Matane, Métis, &c., Cape Rosier, Little 
Fox river, Magdalen river, Ste. Anne des Monts, Cap Chatte, Whale 
cape, Sandy bay, Little Métis, Island of Orleans, Point Lévis, Sillery, 
Cap Rouge, and Chaudière falls and river for the most part referable to 
the Upper Cambrian.
