A lot of valuable information on Canadian geology is available in the form of theses which have been written in partial fulfilment of requirements for degrees at various universities. Generally this information is not extensively used because few geologists know about it. In an attempt to remedy this situation, the editors intend to publish abstracts of stratigraphic, paleontologic, structural and other relevant theses on Canada and bordering areas in this and future issues of the Bulletin. These theses are available on loan from the universities involved. Canadian universities have been contacted for theses abstracts, and universities outside of Canada are also invited to submit abstracts of this nature.

This thesis represents a field and paleontological study of Devonian strata exposed in the Ram River Area west of Nordegg, Alberta, and is intended to present information which will supplement data obtained from exploration drilling of the Great Plains basin.

Certain structural phenomena are discussed in relation to the problems of the Rocky Mountain overthrust belt. It is concluded that overfolding in many cases preceded thrust fault development, that modification of Lawson's equation may be necessary in the consideration of low-angle thrust faults, and that the Eastern Ranges may have suffered less displacement than those of the Western Rockies.

The principles of regional and interregional correlation are discussed with a view to evaluation of the criteria and limitations of biostratigraphic correlation. Previous stratigraphic work is reviewed, and detailed descriptions of the Flume, Perdrix, and Cheviot Formations are submitted. The Perdrix Formation is recognized as being divisable into two new members, the Blackface and Whitegoat Members.

Faunal description, revision, and illustration of five species of corals and thirty species of brachiopods constitute the main part of the work. Revision shows that Leiorhynchus albertense Warren is referable to Calvinaria, and that Bellerophon neleum Hall and Whitfield is referable to Aglaeoglypta. One variety, Calvinaria albertense var. plicata is recognized as new.
