This is a work by a bibliophile for fellow enthusiasts, and the printer has cooperated nobly. It is primarily a catalogue, but in a series of introductory chapters the compiler, as he modestly calls himself, takes a group of friends through the McGill libraries, shows them the greatest treasures, and incidentally reviews the history of vertebrate zoology by saying a few words about preeminent authors and remarkable books. His emphasis is on natural history and faunistic and systemic studies, but he touches on comparative anatomy and paleontology. The oriental literature referred to will be new to most zoologists. Attention is called to important periodicals and serials. There are two convenient classified indexes in which certain authors are grouped according to the classes of vertebrates they have considered and the areas they have covered.
