more recently, an almost exhaustive geological examination 
of the islands, shores and immediate vicinity of lakes Mani- 
toba and Winnipegosis was made by Mr. J. B. Tyrrell in 
1888 and 1889. Assisted by Mr. D. B. Bowling, Mr. Tyrrell 
also made an exceptionally large collection of the fossils of the 
Devonian rocks of this region. This collection, which has 
been reported on somewhat fully by the w'riter in two illus- 
trated papers published in 1891* and 1891,! was found to 
consist of 133 species, but about nineteen of these could not 
then be determined specifically. Two additional species of 
corals in this collection have since been determined, and an 
additional species of Pteropoda from a collection made later 
has been described, making the total of identified or described 
species now known from these rocks to be 117, as follows : 
Sponges (inclusive of Receptaculitidas) 2 
Corals (inclusive of Stromatoporoids) 17 
Vermes i 
Polyzoa (= Bryozoa) 5 
Brachiopoda 18 
Pelecypoda 25 
Gasteropoda 29 
Pteropoda 2 
Cephalopoda g 
Ostracoda 3 
Trilobita. 
Fishes. . . 
117 
According to Mr. Tyrrell these fossils are exclusively from 
the Middle and Upper Devonian of the province, for the Lower 
Devonian has not yet been satisfactorily recognized in 
Manitoba, though it may be represented by about 100 feet of 
red and other shales, from which no fossils have yet been 
collected. In any case they are of special interest as showing 
certain well marked and not altogether unexpected points of 
resemblance to those of the English and European Devonian. 
For, the upper half of the Manitoba Middle Devonian, or 
Winnipegosan formation of Mr. Tyrrell, consists of a tough
