looked rather poor, the main branches being more or less naked 
and new branches few in number. This partly corresponds to 
Kleen’s report (1. c. p. 21) that it »Begins to appear in the begin¬ 
ning of July«; but how far the Fseroese algae are annual, as Kj ell- 
man — according to Kleen — reports being the case with those oc¬ 
curring at Nordland, I am not capable of deciding, I am most in¬ 
clined to think that the basal part of the plant survives the winter 
and gives out new shoots. 
Regarding its habitat Lyngbye writes: — »Habitat ad insulas Fsero- 
enses in inferiore refluxus limite scopulis adnascens, copiose«; this is 
quite true as it is very common on all the shores of the Fseroes which 
are exposed to the open sea. 
The following list of localities will show how commonly it occurs: — 
Str.: Velbestad (!), Kvivig (Lyngb.,!), Hojvig (!); Ost.: Gjov(!), Ejde (!), 
Eldevig (Lyngb.); Bor do: Klaksvig (H. J.); Vid.: Viderejde (!), Vedvig (H. J); 
Svino (H.J.,!); Vaago: Midvaag (!), north side (!); Myggenses (!); San do: 
Troldhoved (!); St. Dimon (!)• Syd.: south-east coast (!), Vaags Ejde (!), 
Trangisvaagfjord (!), Frodebo (!).

In a collection of Callithamnion arbuscula gathered by H. Jons- 
son was found a small Callithamnion which differed from the 
others in habit. By looking through the Callithamnion- material 
preserved in Lyngbye’s Herbarium I found another example of 
the same species. Dr. Bornet, to whom I sent a few specimens, 
kindly tells me that he thinks they are identical with Callithamnion 
granulatum . 
To judge from its few habitats along the Fseroes the species 
must occur there between tide-marks, perhaps associated with Calli- 
thamnium arbuscula and like the latter on exposed coasts. Found 
bearing tetraspores in August and cystocarps and antheridia in 
November. 
This species, which is presumably rare along the Fseroes, has 
hitherto been found only at the following places: — Svino: (H.J.); Ost.: 
Eldevig at the entrance to Fundingfjord (Lyngb.).

In a collection of algse from Ore (Ost.) a few specimens of a 
small graceful Callithamnion were found intermixed amongst several 
other algse; it is remarkable for the fact that the same plant bears 
both cystocarps and antheridia as well as tetraspores. On account
