MUSCI ANTARCTICI. 535 
are species, and the frequent necessity thus imposed on the 
botanist of describing as two what a more copious suite of 
specimens may prove to belong to one. 
The Muscological Herbarium of Sir W. Hooker is now 
under the hands of Mr. Wilson, of Warrington, whose know- 
ledge of that tribe is the most extensive, as he is himself the 
most accurate of muscologists. That my own Mosses may 
be the more perfectly determined, I have, at his kind request, 
confided the whole collection, together with the MS. de- 
scriptions, and drawings of the species, to his able charge, 
both for his assistance in the elucidation of the new species 
and a comparison with those in the Hookerian Herbarium ; 
and I shall here give a part of the results of our labours in 
the following form.
