are mostly taken from various older publications. The present 

 work is a competent attempt to treat completely and inde- 

 pendently a geographical area whose moss-flora shoul 1 by 

 now be fairly well known, but is still greatly in need of re- 

 vision. In starting with the third volume instead of the first 

 the author is taking that group of genera with which he is 

 most familiar, having published revisions of most of them 

 a number of years ago. He has in the meantime changed 

 his conceptions in some cases. That in his treatment of the 

 Hypnaceae he emancipates himself entirely from the recent 

 system of Brotherus-Fleischer in the second edition of Engler- 

 Prantl is a welcome fact, but one is not always persuaded of 

 the correctness of the conclusions reached. For example, 

 the complete separation of Pseudisothecium (new genus) 

 myosuroides and stoloniferum- from Isothecium viviparum or 

 myurum seems extremely dubious. The genus Bryhnia (main- 

 tained both by Grout and Brotherus-Fleischer) has never 

 appealed to me as a natural group. The inclusion in Bestia 

 of Thamnium Holzingeri and Isothecium Brewerianum and 

 the segregation of Brachythecium acwninatiim. and two other 

 closely related species as a new genus Chamberlainia are bold 

 innovations. But whatever attitude of disagreement one may 

 assume on this or that minor point, one is impressed here as 

 always by the independent and essentially accurate scholar- 

 ship of Grout, together with the paedagogical ability to make 

 his publications clear and interesting, which has contributed 

 so much to keep alive American bryology for a generation. 

 This is a substantial contribution to our knowledge of North 

 American mosses.
