1869.] CANADIAN ZOOLOGY. 411 



Dr. Kegel describes no fewer than forty varieties and forms, all 

 named and classified. A. semigaleatwn, not previously noticed 

 as American, is referred as a distinct variety of delphinifolium ; 

 flowers very large, sepals of thin texture, spreading, galea quite 

 depressed with a long acuminate point. These plants are indige- 

 nous, and the specimens of both are from Governor McTavish. 

 The true A. NapeJlus is a naturalized plant. Cimicifuga is con- 

 fined to Cayuga, in the extreme south west of Canada, where it 

 was found by Dr. Maclagan. Actcea rubra is widely spread 

 throughout the whole Dominion, but A. alba is south western. 

 Hydrastis Canadensis is confined to Ontario, and Ado7iis is 

 excluded, as the specimens sent to Hooker from Labrador, 30 or 

 40 years ago, had no doubt sprung from seeds dropped there by 

 accident, and the plant has not been heard of or seen since. 



CANADIAN ZOOLOGY. 



Messrs. Dawson have just issued a " Handbook of Zoology, 

 with Examples from Canadian Species, Kecent and Fossil," by 

 the Principal of McGill University, one who has been engaged in 

 teaching Natural Science and in making original observations in 

 some of its departments. The efibrt is a most useful one, and 

 must prove of the utmost service both to teachers and learners 

 in this country. The intention of the work is to illustrate the 

 subject by Canadian examples, and these are taken both from 

 recent and fossil species, by which means greater completeness is 

 secured, and the work is made useful to collectors of fossils and 

 students of Geology. The tone and character of the work are 

 thus explained in the preface : — 



" In teaching Zoology nothing is of more importance than to 

 have the means of directing the attention of the student to the 

 animals of the country in which he lives. For this reason I 

 have been in the habit of preparing a synopsis of the subject for 

 the use of my class, with examples taken as far as possible from 

 common native species. In preparing a new edition of this 

 synopsis, I was advised by the publisher to give it greater 

 extension, in the hope that it might be useful to other teachers, and 

 to isolated students and collectors. The present manual is the 

 result of this attempt ; and the only merit which it claims is
