WnmurrsT investigating the very extensive collections made by 
Mr. Spruce during his travels up the Amazon and some of its 
tributaries, and afterwards across the Andes, it was at first 
proposed to add, to the list of the species he had collected him- 
self, a catalogue of all other known South-A merican Mosses. He 
afterwards, however, suggested that, as a great many little-known 
species preserved in the Hookerian Herbarium at Kew, and the 
entire collections made by Mr. Weir in New Granada, as well 
as in South Brazil, and also those made by Burchell during his 
travels in Tropical Brazil and down the Tocantins, had been 
examined by me, it would be more advantageous to add descrip- 
tions of the whole of these species, and thus render the enumera- 
tion more complete and comprehensive. All the species, there- 
fore, seen by me have been described, so far as my specimens 
would show, from actual observation. In those instances in 
which my specimens have been defective, I have extracted such 
portions as were necessary to render the descriptions complete 
from such authors as have bad opportunities of observing them 
in a more perfect state; in some instances I have transferred the 
entire description, when the species was either unknown to me
