Brachiopoda 
This group is represented by only one A try pa- like fragment. 
Locality. Anderson headland. 
Horizon . Doubtful. 
Gastropoda 
Madurites sp. A. 
Locality. Magnetic point, Coral bay, Anderson headland, Fossil island, 
Koukjuak (Camp 11), Snowgoose bay, and collected by Eskimo from 
south beach of Amadjuak lake. 
Horizon. Ordovician, probably from the Richmond. 
Maclurites n. sp. B. 
Locality. Snowgoose bay. 
Horizon. Ordovician. The division of the Ordovician, however, is 
doubtful. It is entirely different from the other Maclurites, more 
closely resembling forms from a much lower horizon, but there is no 
other evidence in the collection bearing out such a possibility.

a rather impure coarse sandstone composed of well-rounded grains.

beach of Amadjuak lake. 
Horizon. Upper Ordovician or Silurian.
