ALGiE. 
given by Kjellman of his P. varia and by Harvey of E. distortus 
will show how nearly the ramification of the two plants agrees. 
The filaments of the two are also almost of the same diameter, and 
were it not that we have never seen any chains of unilocular 
sporangia on E. distortus , we should feel inclined to unite the two 
species. The plurilocular sporangia of P. varia are, according to 
Dr. Kuckuck, “ irregular in their form, globular, ovate, or 
ellipsoidal, or of more angular outline to nearly cuboidal, blunt or 
obliquely truncated, never lengthened into a sharp point, mostly 
solitary on short stalks, never sessile, situate on the branches of all 
orders ; shorter or longer intercalary plurilocular sporangia 
abundant on many examples.” The unilocular are “ globular to 
ellipsoidal, mostly solitary, on a single or few-celled stalk, never 
sessile, or several together lateral and terminal on sparsely 
branched short ramuli, seldom united into short chains, situate on 
the branches of all orders.” In both E. distortus and E. Lands - 
burgii the sporangia of both kinds are, in all the specimens we 
have examined, terminal, never intercalary. Most likely E. Lands- 
burgii is only a deep-water form of E. distortus, but we think it is 
premature to unite either one or other of them to Pylaiella 
compacta , Foslie, or P. litoralis , Kjellm. Of course, the specific 
name “ distortus ” has the priority of publication over that of 
“ varius .” 
Bibliography. 
A New African Laminaria (Bulletin de THerbier. Boissier, Yol. 
i., No. 2. February, 1893). 
M. Foslie has received from Dr. Hans Schinz, of Zurich, a new 
Laminaria (L. Schinzii , Foslie) gathered in October, 1890, in 
Walfisch Bay, from a depth of 3 m. 
The diagnosis of the new species is as follows : — L. perennial 
root fibrous ; root-fibres branched, attenuated ; stipe round, solid 
above and below, hollow in the middle, up to 2-5 c.m. in diameter, 
attenuated at both ends ; a transverse section shows muciparous 
lacunse more or less regularly arranged in the intra-cortical layer; 
lamina often elongated, cordate or cuneiform at the base, deeply 
split into from 5-19 segments, 1-5 to 6-5 c.m. wide, coriaceo-mem- 
branaceous : sori forming dispersed patches on the upper part of 
the segments, of various shapes and sizes, 62-74 p wide ; zoo- 
sporangia subcylindrical, 36-50 p long, 7-10 p wide; paraphyses 
elongated, wedge-shaped. 
f. typica, Foslie. 
Stipe longer, lamina ovate or cordate. 
f. cuneata, Foslie. 
Stipe shorter, lamina lanceolate, longer and narrower than in the 
preceding variety. The specimens examined appeared to be young. 
This paper is illustrated by a pretty plate.
