B. 2.— FROM DAVIS POINT, LAKE l^FANITOBA. 



Collected by J. B. Tyreell and J. F. Whiteaves in 1888. 



The section at this locality is thus described on pages 195 and 196E 

 of Mr. Tyrrell's " Report on North-western Manitoba, with portions of 

 Assiniboia and Saskatchewan," in the Annual Report, New Series, Vol. 

 V, pt. 1, of this Survey for 1890-91. Mr. Tyrrell's Report is dated 1892, 

 but the volume of which it forms part is dated 1893. 



"North west of the head of the Fairfield River the shore of the lake is 

 generally low, and it is not till the vicinity of Davis Point is reached that 

 the Silurian again makes its appearance. At the southern end of this 

 low exposure, a thin and even-bedded dolomitic limestone crops out of the 

 bank near the water's edge, and many slabs of the same rock are scattered 

 over the shore. No fossils were found in it, but it is doubtless the same 

 band as is exposed at Fairford. 



" At the north end of the exposure, and apparently overlying the last 

 mentioned rock is a layer of very thick-bedded limestone, also slightly 

 dolomitic. It is yellow, hard and tough, but not compact like the last, 

 being largely composed of the debris of Stromatoporoids and corals. It 

 weathers white, with a very rough surface." And it is from this upper 

 layer that the following species of fossils were collected. 



ANTHOZOA. 



Tetbacoralla. 



Zaphrentis Stokesi, Edwards & Haime. 



One specimen, which Mr. Lambe thinks is most probably referable to 

 this species. 



Pycnostylus Guelphensis, Whiteaves. 



Apparently common at this locality, though only a few specimens were 

 collect-ed. 



Hexacoralla. 



Favosites Gothlandicus, Lamarck. 



Apparently also common at this locality. 



HYDROZOA. 



(Clathrodictyon osiioZaiMm, Nicholson, andC. vesiculosum, Nicholson and 

 Murie, are quoted by Mr. Tyrrell as having been collected at Davis Point
