3. Chantransia hallandica Kylin. 
H. Kylin (1906) p. 123. 
Ch. parvula Kylin (1906) p. 124. 
Kyrın in 1906 described two allied species, Ch. hallandica and Ch. parvula, 
differing from each other by the filaments being a little thinner, giving branches 
off at all sides and consisting of longer cells, further by the sporangia being often 
stalked and then usually placed two or three together in Ch. hallandica, while 
Ch. parvula is smaller, 
has shorter, a little 
thicker filaments with 
branches placed in one 
ortworows and usually 
sessile sporangia. In se- 
veral places in the Da- 
nish waters I have met 
with Chantransiæ agree- 
ing exactly with these 
two species, but I have 
also found specimens 
which were intermedi- 
ate in regard to one or 
more of the characters 
mentioned. As I have 
also found sexual or- 
gans, besides the spor- 
angia described by Ky- 
LIN, it will be necessary 
to mention these plants 
more closely.

3, at the most 4 erect filaments, (4—)5—6 y thick and consisting of cells usually 
3—4 (—5) times as long as broad. Hyaline hairs are usually present. The origi- 
nally terminal hair is often pushed aside by the cell bearing it growing out sym- 
podially in the same direction as before, and the hair leaves then only a faint 
mark at the upper end of the cell which has produced it; but in other cases the 
hair retains it terminal position, and the filament, i.e. the branch, grows out in 
another direction (fig.21 E). Transitional cases are also found. The cells contain
