Although most of these are reported from the Rocky Mountain area, several species from the Mackenzie River-Mackenzie Mountains area are also included. In addition, species reported from the Upper Devonian Outcrops east of the Rocky Mountains have been dealt with. Numerous taxonomic problems encountered in the study are discussed in remarks on the genera and species involved. Fossil corals collected from the region drained by the headwaters of the North Saskatchewan River are described, identified and illustrated. Nine genera and 14 species are recognized in the collection. Of these, 1 genus and 4 species do not appear to have been previously reported to occur in the Upper Devonian beds of the Rocky Mountains in ...
