(Continued from Vol. iii, Second Series, p. 80.) 
the continuation of the list of Alge hitherto found in the 
United States, I have thought it best to “adopt for the Confervee, 
the names employed by Harvey, in his Manual of British Alge ; 
for although the recent subdivisions of the old and heterogeneous 
genus Conferva, are doubtless necessary and proper, yet Algolo- 
gists do not seem agreed as to what names shall be generally 
adopted. The old and well known names will answer all my 
present purposes.

and therefore can only present the following memoranda, which 
I made while examining them, some time since, in Dr. Torrey’s 
herbarium. I give in one column the names attached by Schwei- 
me and in the other the more modern names, where I have been 
to determine them from the often’ unsatisiactory examination 
of the dried specimens.
