line figures of all known British species, and although the author 
speaks of this as being “ little more than an illustrated catalogue,” 
yet many cryptogamists would doubtless readily acknowledge their 
indebtedness to it. 
It is well known that Dr. Cooke has for many years devoted the 
greater part of his time to the Fungi, and clearly explains his 
position as follows, after yielding to the frequently expressed 
desire on the part of many that he would expand his previous 
work into a manual : — “ I have felt diffidence, since for many 
years another branch of the Cryptogamia has absorbed so much of 
my time and attention, that I have been unable to collect and 
study the Hepaticas in the field, and therefore have to be content 
with the chronicle of the labour of others rather than my own.” 
The attempt to bring together the scattered literature of the 
last half century is a decided success ; British students of this 
most interesting group of plants have now at their command an 
excellent text-book, well up to date ; all sources of information, 
British and foreign, have been sifted, and every point of importance 
incorporated. The introductory chapter deals with structure and 
affinity. A concise diagnosis is given of each species, followed by 
a full synonymy, and, lastly, copious notes indicating general 
structure, points of agreement and of difference with allied species, 
are given. The outline figures, illustrating every species, add 
greatly to the value of the work. The type is bold and clear, and 
the general finish of the book good.

Enteromorpha xhacodes, n. sp. 
E. pallide viridis, fronde membranaceo-papyracea, hic illic irregu- 
lariter dilatata, densissime ramosa, ramis linearibus, patentibus, 
tortis, per totam longitudinem ramulos longiores vel breviores, 
simplices vel ramulosos, patentes, curvatos, aculeatos, emittentibus. 
Fronde diplostromatica, a?tate separante, cellulis polyhedris, 
rectangularibus vel quadratis, sine ordine positis, endochromate 
subconforme majorem partem cellulae occupante, instructis.

Judging from the specimens received, the plant appears to form 
floating masses like E. percursa. The long slender branches, 
covered with curved spine-like branchlets, are almost inextricable, 
and, owing to their fragility when moistened, it is nearly impossible 
to mount a perfect specimen. For the same reason the base of 
the plant has not been observed. In some pieces the frond 
appears to be dilated into an ulvoid expansion, but in these 
portions the two layers of cells separate, as in Enter omorpha 
Linza.
