Ormoceras sp. 
Locality. Fossil island, Koukjuak (Camp 11). 
Horizon. Probably Silurian. 
cf. Elrodoceras n. sp. 
These specimens are allied to Elrodoceras, but with characteristics 
that are somewhat different. Further collections may prove that they 
are a new genus. 
Locality. Coral bay, Anderson headland, Fossil island, Koukjuak (Camp 
11), Snowgoose bay, and collected by Eskimo from the south beach of 
Amadjuak lake. 
Horizon. Upper Ordovician or Silurian. 
The specimens from the northwest side of Amadjuak lake south of 
North bay are mainly composed of concretionary-like nodules with a few 
very poorly preserved bryozoa as a nucleus and one specimen of Illaenus 
sp. from the Upper Ordovician or Silurian. 
The collection from the dark shale in the “drift” on the low beach 
beside the lake at Coral bay, Nettiliing lake, exhibits fossils strikingly 
identical with those in similar shales of the Utica (Collingwood) in Ottawa 
valley and west of Collingwood, Ontario. The light grey weathering of 
the dark shales is also characteristic of the Ontario beds. The thin shales 
of the collection are so little broken that they are evidently almost in situ. 
Such a distribution of beds with an assemblage of fossils practically 
identical is an interesting witness as to the wide extent of similar conditions 
in the Utica (Collingwood) sea. The following fossils are present in the 
dark shale collection : 
Bryozoa 
cf. Chasmatopora sp. 
An identical parasitical bryozoa on the same cephalopod has been re- 
ferred to the above genus from the neighbourhood of Ottawa. It is not 
certain that the generic reference is correct in either case, but the specimens 
to hand, though numerous, are too poorly preserved to alter the previous 
determination. 
Brachiopoda 
Leptobolus insignis Hall 
This species is very numerous. The specimens seem to average 
a little finer and smaller than the Ottawa representative, but otherwise 
appear to be identical.
