Cephalopoda 
cf. Trocholites ammonius Conrad 
The specimen is doubtfully referred to this species because poorly 
preserved. Its form, however, is practically identical with similar crushed 
specimens in Ottawa valley. 
Endoceras proteiforme Hall 
Numerous endosiphons covered with the encrusting bryozoa mentioned 
above. 
Trilobita 
Ogygiies canadensis (Chapman) 
In summing up the evidence of the fauna, it is quite clear that the 
Ordovician fauna of Baffin island here represented includes, besides the 
Trenton of Schuchert’s reports 1 and the Utica (Collingwood) fauna given 
above, some representation of the Richmond. One fossil, Maclurites sp. A, 
as stated above seems to be much more closely allied to the forms from the 
Reekmantown of Newfoundland than to any other Maclurites, but no evi- 
dence points to beds so low in the Ordovician and it is left a species of 
doubtful horizon. 
The presence of the Silurian is clearly demonstrated both by corals 
and cephalopods.
