By W. Wilson, Esq. 
Of the Tasmanian Mosses (about 250) here described, the majority (180) were collected by Mr. Gunn and 
myself, and have been elaborated by Mr. W. Wilson; the remainder consists of additions to the Tasmanian 
Flora, chiefly made by my friend W. Archer, Esq., F.L.S., of Cheshunt, and which have been examined and 
described by Mr. W. Mitten. Mr. Mitten has indeed prepared a paper on Mr. Archer's Mosses, which 
will be presented to the Linneean Society of London; and I have to acknowledge my great obligations to 
him for allowing me to insert his descriptions of the new species here, as well as for some valuable notes 
on Gunn’s Mosses and my own; these I have appended to Mr. Wilson's descriptions as this work was 
passing through the press. 
There are no doubt very many fine Mosses to be discovered in Tasmania, especially on the lofty moun- 
tains, and on the damp western and southern coasts. A large proportion will probably prove identical with 
New Zealand species, and with those of Fuegia and the Antarctic Islands. In the New Zealand Flora 
upwards of 250 species of Mosses are described by Mr. Wilson, and many have been discovered since 
especially by Mr. Knight, raising the number known to upwards of 300.—J. D. H.
