“ Spores oblong, -0004 in. long, not irregular, and more or less 
angular, as in the plant usually referred to, A. depluens , as figured 
by Hoffmann, so that its affinities seem rather to be with Crepi- 
dotus than Claudopus. The present is exactly the plant .of Batsch, 
and we think it better to leave the name with what has formerly 
been considered his species, and retain that of Persoon. The gills 
of A. epigceus are no longer red when dry.” — B. Br. 
AGARDH’S CLASSIFICATION OF ALGiE.* 
Although this work by the Emeritus Professor of Botany at 
Lund has a Swedish title and preface, it is written in Latin. Its 
purport will be best understood by the following translation of the 
short preface : — 
u During the third part of a century which has elapsed since the 
publication of the first part of ‘ Species, Genera, et Ordines 
Algarum,’ my Algological studies have been principally devoted to 
the Florideae. It will be easily understood that during this long 
period many new species have been discovered among the groups 
which I three years ago associated under the name of Fucoideae, 
and that there have been made many observations which render it 
necessary to modify some of the views which are therein expressed. 
I have, therefore, thought it expedient to return in the present 
work to some of the groups which seem most to need a critical re- 
vision.” 
The groups selected for this purpose are the Chordariese and 
Dictyoteae. The former group now comprises the following genera, 
namely : — 1, Elachistea (sic) ; 2, Myriocladia ; 3, Corynophlaea ; 
4, Bactrophora ; 5, Mesogloia ; 6, Eudesme ; 7, Castagnea ; 8, 
Leathesia ; 9, Cladosiphon ; 10 (?) Petrospongium ; 11, Poly- 
cerea; 12, Liebmannia ; 13, Myrionema, Herponema ; 14 (?) 
Ralfsia ; 15, Csepidium ; 16 (?) Scytothamnus ; 17, Chordaria. 
Of these five genera are new, namely, Bactrophora, the three
