Sullivant’s Muscology. 71 
The collection fills two large quarto volumes, and comprises 
215 species or marked varieties of true Mosses, and 77 of Hep- 
alicee,—in all 292. We should render a service to this beautiful 
and too much neglected department of American botany by copy- 
ing the whole list : we will at least find room for the new species 
which. are here proposed and characterized ; since the work must, 
from the necessity of the case, have but a limited circulation, 
and may fail to reach many who are interested in the subject. 
In these instances we copy the original tickets entire, with the 
numbers under which they appear, as follows.
