5. The Fossils of the Silurian (Upper Silurian) rocks of Keewatin, 



Manitoba, the north eastern shore of Lake Winnipegosis, 



and the loiver Sa^katuhewan River. 



By J. F. Whiteaves. 



A. FROM KEEWATIN. 



A. 1.— FROM THE ATTAWAPISKAT RIVER. 



Collected by Dr. R. Bell in 1886. 



The exposures of fossiliferous limestone on the lower portion of this 

 river are described on pages 27g and 28g of Dr. Bell's " Report on an 

 exploration of portions of the At-ta-wa-pish-kat and Albany rivers, Lonely 

 Lake to James Bay,'' which forms part of the Annual Report of this 

 Survey for 1886, New Series, vol. II. The fossils were collected at 

 Rainy Island (N. Lat. 53° 05', W. Long. 84° 2.3') and seventeen to thirty 

 miles below Rainy Island. Those from the first of these localities are 

 referred to on page 27g, and those from the second on page 286, of Dr. 

 Bell's Report. In that report, the few and for the most part fragmen- 

 tary fossils from each of these localities were provisionally stated to be 

 probably of Devonian age. But, the subsequent receipt of a, fine series 

 of fossils from similar rocks on the Ekwan River, collected by Mr. Dow- 

 ling in 1901, has convinced the writer, as elsewhere stated,* that not only 

 the fossiliferous limestones of the Attawapiskat, but also those of the 

 Fawn River (or branch of the Severn), are of Silurian age.
