PALEOZOIC FOSSILS. 



■VOL. III. 



S. Systematic list, with reftrences, of the fossils of the Hudson River or 

 Cincinnati formation at Stony Mountain, Manitoba. 



By J. F. Whiteaves. 



In a letter written by Sir James Hector, dated Fort Carlton, December 

 14th, 1857, and published in the official report of Captain Palliser's Ex- 

 ploring Expedition,* the following passage occurs : — "At Stony Hill, about 

 fifteen miles north-west from the Upper Fort, there is an isolated bluff of 

 limestone, rising from the plain level to the height of eighty feet. The 

 south and western exposures are abrupt and water worn, it having been 

 at one time an island ; and indeed, during the great floods which several 

 times inundated the settlement, it has been one of the few spots upon 

 which the inhabitants can take refuge, reaching it by means of boats. 

 The beds of limestone are horizontal or nearly so, and are slightly different 

 from those at Fort Garry in their mineral aspect, having a more crystalline 

 fracture and the colour being of a reddish hue. No fossils can be dis- 

 covered in newly fractured portions, but on the weathered surfaces a few 

 obscure remains of fossils are to be seen projecting along with siliceous 

 and gritty particles from a dull floury surface." 



On the occasion of a short visit to this locality (now more generally 

 known as Stony Mountain) in 1875, Dr. R. W. Ells noticed that pieces of 

 limestone and shale thrown out while excavating for the foundation of 

 the provincial penitentiary then in course of construction there, were full 

 of fossils in a remarkably fine state of preservation, and made as large a 

 collection of them as the time at his disposal would admit. Lists of most 

 of the species represented in this collection and in one made at the same 

 place by Dr. R. Bell in 1879, were contributed by the writer to the Report 

 of Progress of this Survey for 1878-79 (pp. 49 and 50C), published in 1880, 

 and it was there stated that " a large portion of the mass of Stony Moun- 

 tain consists of limestones, with clayey partings, which are identical, both 

 in their lithological and palseontological characters, with the well known

 North America which lies between the north branch of the River Saskatchewan and 

 the frontier of the United States, and between the Red River and the Rocky Mountains.
