162 KJELLMAN, THE ALG OF THE ARCTIC SEA. 
cortical layer consists of small cells the greatest extent of which is at right angles to 
the surface of the frond; fig. 6. 
Reproductive organs are unknown. 
I have supposed Croatu’s K. reniformis to be the present species, but I have not 
seen any specimens of it. 
Habitat... This plant is sublitoral, attached to other algw, as Ptilota pectinata and 
Lithothainia, or to small stones and old shells. It grows scattered on exposed cvasts. 
The species probably develops its reproductive organs later in the year than it has 
been observed hitherto. Most of the specimens found by Kieren at Nordlanden in July 
were young. At Finmarken at the beginning of August I met with only very small 
and young individuals. But in the arctic region I have collected some older and, I 
suppose, full-grown specimens in July. 
Geogr. Distrib. It is known with certainty from the Norwegian Polar Sea, the 
eastern Greenland Sea, and the eastern Murman Sea. It has been found most common 
on the north coast of Norway. Its most northerly known locality is Treurenberg Bay 
on the north coast of Spitabergen Lat. N. 79° 56’. 
Localities: The Norwegian Polar Sea: Nordlanden, not rare; Finmarken, at Maas6, 
very plentiful, but local. 
The Greenland Sea: the west coast of Spitzbergen at South Cape, washed ashore; 
the north coast at Musselbay and Treurenberg Bay, local, scarce. 
The Murman Sea: Rogatshew Bay on the west coast of Novaya Zemlya, local, scarce. 
Baffin Bay: without the locality being definitely stated, in case CroaLy’s K, reni- 
formis belongs to this species. Cp. Croat, |. e.

Remark on the determination of the species. I have referred to this species two 
specimens of Kallymenia from Greenland, preserved in the herbarium of the Copenhagen 
Museum, taken by WormskioLp and determined by Mertens as Fucus palmatus. Har- 
vey'’s description of the present species accords well with them. They resemble much 
K. reniformis, but they are thinner than individuals of this species and their inner 
central cell-filaments are less dense. In colour they are pale red-brown. The one 
specimen is elongated in circumference, the other broadly reniform, the former is 
deeply divided, almost palmate, the latter irregularly lobed with slender or broad ob- 
ovate, or linear, entire or subdivided lobes. The edge bears a few triangular teeth. 
The sporocarps are immersed in the upper part of the lobes near their surface, but 
not prominent above it, numerous, small, containing few spores with rounded angles. 
If my determination of these specimens is correct, K. Pennyi is nearly related on the 
one side with XK. reniformis, on the other with KX. ornata Post. et Rupr. It is distingui-
