6 Nr. 4. L. KoLDERUP ROSENVINGE: 
a parasite. The origin of the latter was not, however, ex- 
plained. The name Actinococeus is then given to the para- 
site that comprises not only the nemathecial bodies but 
also the intramatrical filaments. At the end of Schmitz’s 
paper the parasite is given the name of Actinococcus sub- 
cutaneus (Lyngb.) Roseny.' 
ScHMITZ’s discoveries were tested by the French al- 
gologist GOMONT who convinced himself of the accuracy 
of Scumirz’s observations by an anatomical investigation 
of material in the Muséum d’histoire naturelle in Paris. 
On the other hand, REINKE became doubtful as to the 
correctness of the independence of “Actinococcus roseus”, 
which was no doubt connected with the fact that O. V. 
DARBISHIRE, then assistant at the Botanical Institute at Kiel, 
was working at the question. In a preliminary note (1894) 
and a very valuable monograph of the Phyllophora species 
in the western Baltic (1895) DARBISHIRE described the 
structure and development of the organs of reproduction 
and as to the nemathecia arrived at a view opposite to 
that of Scumirz. He gave a careful description of the an- 
theridia which arise in crypts sunk in the cortical layer of 
particular small shoots, “spermophores” at the upper end 
of the flat fronds. He further described the female shoots 
that, when young, much resemble the spermophores and 
like these are placed at the upper end of the frond (comp. 
fig. 47 I), whereas the older carpophores are said to be 
placed like those of Ph. membranifolia at the borders of the 
flat frond and have much the same appearance as those 
of this species. He found procarps, not before observed, in 
the young female shoots, and imagined that these shoots 
* LYNGBYE's specific name of 1834 remained unnoticed till I called 
attention to it (1893, p. 822).
