a more or less sterile belt. The erect filaments are about 70—100 y 
long and about 9 \jl broad. 
The plurilocular sporangia are most commonly sessile, but 
stalked examples also occur. They are oblong-ovate, often some¬ 
what tapering towards the top, and are about 20 y thick and about 
50 y long. I have not observed quite ripe or emptied sporangia, 
nor did I come across hairs. 
This plant, which formed small, dark-brown patches on the 
lamina of a Laminaria , was found bearing plurilocular sporangia 
in October. 
Found hitherto only on Str.: Kvalvig (H. J.).

Found endophytic in Polysiphonia urceolata and Callithamnion 
scopulorum which grew between tide-marks as well as in the sub¬ 
littoral zone in more shallow water. 
Sporangia-bearing specimens were observed in June.

It has been met with in a few places only, but is doubtless rather 
widely distributed. 
107. M. Zosterae Kuck., 1. c. p. 25. 
Grows on Zostera marina exactly in the way as described by 
Kuckuck amongst Diatoms on the epidermis of Zostera. It often 
forms fairly large pseudo-parenchymatous patches such as those 
observed by Svedelius 1 near Gotland. 
Found only on Syd.: Vaagfjord (!).

A small, brown crustaceous alga, which was found on a Chce- 
tomorpha Melagoninm gathered near Thorshavn, exactly agreed with 
Wille’s description and figures (1. c.). It had a quite similar basal
