valley, forming a marine gulf rivalling in extent the similar invasions 

 of the sea in Palaeozoic times. The direction of motion of the ice varies 

 from S. 7° W. to S. 18° W. 



The report also contains much information concerning the fauna, 

 flora and timber resources of the district, and has appendices giving 

 Lists of Elevations and Catalogues of the Paleozoic Fossils.

 Part I. A Revision of the Genera and Species of Canadian 

 Palreozoic Corals. The Madreporaria Perforata and the Alay- 

 onaria, by Lam^rence M. Lambe, F.G.S., Assistant Palaeonto- 

 logist. Ottawa, 1899. 

 Corals, as is well known, form a large proportion of the fossils 

 found in the Palaeozoic rocks of Canada. Unfortunately, however, 

 the classification and nomenclature of these corals have long been in a 

 state of some confusion. With a view to remedying this, Mr. Lambe 

 has undertaken a revision of the genera and species. The present 

 report on the IMadreporaria Perforata and the Alayonaria, this 

 brochure of 96 pages with five plates, forms the first part of the fourth 

 volume of " Contributions to Canadian Palaeontology." A second 

 part, now in course of preparation and to be illustrated by thirteen 

 plates, is intended to conclude the revision of this class so far as pre- 

 sent material permits. 



The publication will be of much value to all members of the 

 Montreal Natural Histoi'y Society who are interested in the palaeon- 

 tology of this vicinity, and Mr. Lambe deserves the thanks of all 

 Canadian naturalists for the careful and painstaking manner in which 

 he had carried out the work which has been entrusted to him.
