 This volume, issued under the direction of the Geological 



Survey of Canada, will be heartily welcomed by botanists the 

 world over as a valuable addition to the scientific stores of the 

 North American Continent. By this publication, the veteran 

 author acquires new laurels as the Nestor of the botanists of 

 the Western world. It is pleasant to note how cordially his 

 fellows in the prosecution of this branch of science have re- 

 cognized the service he has rendered to it by affixing his name 

 to a large number of the species described in this volume, and 

 thus his zealous work becomes honourably commemorated and 

 perpetuated. The distinction has been well earned by the 

 Herculean labour which he has successfully performed, the 

 results of which are embodied in his reports to the Govern- 

 ment of Canada. The list of Hepaticae embraced in this pub- 

 lication — 196 species and 7 varieties — includes the catalogue 

 of 165 species already reported in 1890, as determined by 

 William Henry Pearson, although the latter are, many of 

 them, classed differently. Only one of the Hepaticae, 

 Anthoceros Macouni (Howe), is described, because of its being 

 hitherto unfamiliar to students of this department of botany. 



The Lichens reported number 614 species and 119 varieties, 

 of which only one species and three varieties are described, 

 from which we are to conclude that the rest have been pre- 

 viously identified as occurring in Canada and elsewhere. 



Nearly one-half of the volume is taken up with additions 

 to the list of Mosses, published in 1892 by the Geological Sur- 

 vey. The number previously catalogued was 953. This num- 

 ber is now raised to 1,196, besides 77 sub-species and varieties 

 given in this volume. A new Genus, " Bryo Brittoma," is
