PREFACE. 
This Catalogue of North American Mosses and Hepaticse 
has been prepared as a check and exchange list, and a basis for 
arrangement of herbaria. 
It is based upon the “Manual of Mosses of North America,” 
by Leo Lesquereux and Thos. P. James, and the “Descriptive 
Catalog of the North American Hepaticae, North of Mexico,” 
by L. M. Underwood. It is thought unnecessary to give the 
distribution of the species, as that is given in these works. 
At the suggestion of Prof. Underwood, the arrangement of 
Orders and Genera, as given in his Catalog, is reversed, that 
these may be placed in their proper relation to Mosses. 
The following Mosses not given in the Manual will be found 
in the Addenda : 
Hypnum occidentale, Sulliv. and Lesq 
— Botanical Gazette^ vol. 9, p. 195. 
Hypnum Barberi, Renauld. 
“ serpens, L. var. 
Barberi, Renauld. 
— American Nattiralist, vol. xvii., pp. 821-2. 
Exchange of Mosses solicited.
