rum” (p. 415). Inthe authentic material that we have examined, 
collected in Java by Zollinger, the filaments are mostly 215-315 и 
in diameter. The cell walls are very much thinner than in 
Cladophoropsis herpestica, being only 5-11 и thick. This character 
and the shorter, more slender filaments should probably be deemed 
sufficient, for the present, to justify considering C. Zollingeri 
distinct from C. herpestica.

while the third, the lowest of the three, has none. 
2. A portion of a filament showing two nearly opposite branches of which one has a 
basal septum and the other has none.

. Apex of a filament showing a short apical cell and a branch with lumen continuous 
with that of the main filament. 
5. Apical portion of a filament with four secund lateral branches, of which the lowest 
n incomplete septum at the base and the remaining three have a con-

Cladophora Hariotiana sp. nov. 
ft, gelatinous, dark- or yellowish-green, slightly nitent, 
forming dense tufts 8-30 cm. long; main filaments 150-340 и in 
diameter, somewhat flexuous, virgately branched with percurrent 
monopodial axes, the branches mostly 3-6 cells apart, flexuous, 
erecto-patent, distinctly lateral or arising by a false di-trichotomy, 
the two or three branches in the latter case of very unequal length, 
the longer branches once or twice compounded like the main 
filaments; ultimate lateral branchlets 35—55 м in diameter, about 
one half the diameter of the filaments from which they spring, 
gradually tapering to a blunt point, suberect or erecto-patent, 
often slightly incurved, the lower 6-8 cells long, the upper mostly 
2-4 cells long, usually secund and arising from nearly every cell 
of the rachis, this excurrent for 3-5 cells; cells of the main fila-
