In the preface the authors claim to have arranged according to 
their alliance 1350 species of North American mosses, but they do” 
not include those of Mexico or Central America. This list does 
not claim to be a critical revision, but simply an enumeration t 
date of all the published species since the issue of the Manual, giv- 3 
ing their range geographically, also indicating whether endemic or 
common to both Europe and the U.S. This first part includes 
710 species, the varieties not numbered. We note one erro!
