give some slight idea of what has been done. In the present part, 
Professor Macoun records 1,070 species and varieties as the total moss 
flora of Cauada ; thus he gives a much larger record, for the Dominion 
alone, than is given by Lesquereux and James in their “Manual of 
the Mosses of North America,” published in 1884. This volume 
included not only the United States but also Canada, their record 
being 1,020 species and varieties. But this comparison does notin any 
way represent the real value of Professor Macoun’s work. Of the 1,070 
mosses which he records, 400 species and varieties are given in “The 
Catalogue ” that are not recorded in “ The Manual,” so that Professor 
Macoun has raised the moss flora of America from 1,020, as given in 
“ The Manual ” to 1,420 ; and, what is still more remarkable, of these 
400 additional plants, upwards of 200 are neiv to science, so that it may 
be truly said this work is an epoch in American bryology. In 1887 
Professor Macoun began to correspond with the great Swedish 
bryologist, Professor Nils Conrad Lindberg, who examined great 
numbers of the mosses collected ; the assistance of Dr. Carl Mueller, 
of Halle, was also obtained. To our greatest living authority on that 
difficult genus, Ortliotrichum, Dr. Venturi, the various specimens of 
that group were sent for confirmation or determination, while 
Dr. Warnstorf, of Neuruppin, has examined all the specimens of 
Sphagnum, so that the record is stamped by an authenticity of 
unquestionable value. The present part abounds throughout with 
notes and observations on the minuter differences to be observed in 
these plants, and all the new species are fully and ably described, so 
that the work is of real value to every moss student, and its author 
may be congratulated on having so well fulfilled the promise given in 
the preface to the first part of “ The Catalogue ” :— 1 ‘ The purpose of this 
work is to place in the hands of Canadian botanists, in a connected 
form, the knowledge so far obtained of the extent and distribution of 
the flora of Canada.” This has been carried out even beyond the 
author’s expectation ; he has presented to the Canadian botanist a 
work that must command his respect and admiration, and one that 
will be the basis of all future floras of Canada.

Second Edition. Revised and Augmented. London : Swann,

The demand for a second edition of this book seven years after the 
publication of the first, has given the author the opportunity of 
correcting errors and making additions, which have greatly added to 
the value of his work. To the other corrections, however, we wish 
one addition had been made—that the term Arthropoda had been 
substituted for Annulosa as the title for that division of the animal 
kingdom to which the Insects are assigned, since Mr. Kirby must be 
aware that the latter name has dropped out of use among the leading 
comparative anatomists of the day. The term Annulosa (with the 
alternative Articulata) is objectionable, because it was formerly used to
