4 MR. W. MITTEN ON THE MOSSES OF THE EAST INDIES. 
The materials for the present enumeration have been derived 
from the collections of Buchanan Hamilton, Gardner, and Wallich, 
in. Nepal; Strachey and Winterbottom, in Kumaon; Royle, in 
the North-west Himalaya; Perrottet*, Schmid, Foulkes, Melvor, 
Gardner, and G. Thomson, in the Nilghiri Mountains; Griffith, 
in Assam and the Khasia Mountains ; Law, in the Concan ; Wight, 
near Madras; Gardner, Thwaites, Walker, and Maxwell, in 
Ceylon; and Wallich and Parish, in Pegu ; but more especially 
from those made by Dr. Thomson in North-west India and Western 
Tibet, and by Dr. J. D. Hooker in the Sikkim-Himalaya and East 
Nepal, and in conjunction with Dr. Thomson in the Khasia Moun- 
tains in East Bengal. 
Through the great liberality of Sir W. J. Hooker all the original 
specimens from whence the descriptions and figures in the ‘ Musci 
Exotici’ and ‘Icones Plantarum Rariorum’ were derived, have 
been examined; and, lastly, the entire extensive collections of 
Dr. Thomson and Dr. J. D. Hooker were entrusted to the author 
for segregation and distribution. A manuscript catalogue of these 
has been prepared by Mr. W. Wilson, and is in part published in 
the last volume of the ‘ Kew Journal of Botany ;’ but the determi- 
nations are in many cases doubtful, and no descriptions accompany 
it. I have, however, adopted many of the names applied to the 
new species, and quoted the MS. in the following enumeration. 
Hurst, Sussex, March 1858. 
Obs. A mark of admiration (!) is affixed to the names of the 
collectors whose specimens have been examined; its absence 
denotes that such specimens have not been seen by the author. 
* Dr. Montagne very kindly communicated all the species of interest col- 
lected by Perrottet. 
+ For the correct understanding of many of the species figured and described 
in Griffith’s “ Posthumous Papers,” I am indebted to N. B. Ward, Esq., who 
kindly submitted to me all the specimens he received from that author, which 
were accompanied with descriptions corresponding with those in the ‘ Notule,’ 
published at Calcutta, but which are very little known, if at all, to European 
bryologists.
