Fig. 5. Enteromorpha kylinii: Habit of part of a tuft, 
X 1.25. 
Enteromorpha kylinii Eliding 1948: 1, figs. 
1-3 (west coast of Sweden) 
Fig. 5 
LOCAL DISTRIBUTION: Densely tufted, Sta. 
2 (11068); on shells and algae, Sta. 4 (11178). 
These specimens are in good agreement 
with Bliding’s account. The cells are arranged 
in longitudinal rows with two or more pyren- 
oids per cell.

Fig. 6d, e 
LOCAL DISTRIBUTION: Forming a dense, 
hairy covering 1-3 cm. high on rocks, Sta. 
6 (11225); entangled among other algae in 
drift, Sta. 3 (11096). 
The slender, abundantly branched plants 
of 11096 are in good agreement with Blid- 
ing’s Type II of this variable species. Those 
under 11225 are more sparsely branched, but 
otherwise similar. All have two or more pyren- 
oids per cell and the cells arranged in -f — 
definite longitudinal rows, usually more so 
than shown in Fig. Ge. 
Enteromorpha tubulosa (Kutz.) Kutzing

morpha intestinalis var. tubulosa Kutzing 
1849: 478 (Europe) 
Fig. 6a, b 
LOCAL DISTRIBUTION: Entangled in Hypnea 
growing on sand flats near Sta. 12 (11403). 
For practical purposes of recognition I fol- 
low Setchell and Gardner (1920) in assigning 
this unbranched, entangled plant to E. tubu- 
losa, although other authors, particularly 
Eliding (1939) through his interfertility stud- 
ies, have recognized it as a form of E.proUfera 
(Miiller) J. Ag. 
Key to the Species of Chaetomorpha 
1. Filaments attached, tufted .2 
Filaments mostly unattached, entangled, 
contorted . . . C. crassa 
2. Basal cells very long, with annular con- 
strictions near the base; upper cells much 
longer than broad ........ C. antennina 
Basal cells not exceptionally long, not 
constricted; upper cells about as long as 
broad 3 
3. Cells of + “ variable length above; di- 
ameter 60-90 /i C. indica 
Cells -f — uniform above; ‘diameter 50-

Fig. 6h-j 
LOCAL DISTRIBUTION: Growing in hank- 
like tufts on the sea wall, Sta. 6 (11231). 
These plants agree as to basal cell, filament 
diameter, and cell dimensions with this spe- 
cies as illustrated by Kutzing, although the 
cell walls of his specimens were apparently 
thinner than those of mine.
