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 siirface of the frond; iig. 6. 



Reproductive organs are unknown. 



I have supposed Ceoall's K. reniformis to be the present species, but I have not 

 seen any speciraens of it. 



Habitat. This plant is sublitoral, attached to other algas, as Ptilota pectinata and 

 Lithothamnia, or to small stones and old shells. It grows scattered on exposed coasts. 

 The species probably develops its reproductive organs låter in the year than it has 

 been observed hitherto. Most of the specimens found by Kleen 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, fuU-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 Spitzbergen Lat. N. 79° 56'. 



Localities: The Norivegian Polar Sea: Nordlanden, not rare; Finmarken, at Maasö, 

 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 Mur man Sea: Rogatshew Bay on the west coast of Novaya Zernlya, local, scarce. 



Bafjin Bay: without the locality being detinitely stated, in case Croall's K. reni- 

 formis belongs to this species. Cp. Croall, 1. c.

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 Woemskiold and determined by Mertens as Fucus palmatus- Har- 

 vey's description of the present species accords well with them. They reserable much 

 K. reniformis, but they are thinner than individuals of this species and their inner 

 central cell-iilaments are less dense. In colour they are påle red-brown. The one 

 speciraen 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 snbdivided lobes. The edge bears a few triangulär teeth. 

 The sporocarps are immersed in the upper part of the lobes near their surface, but 

 not prominent above it, numerous, small, containing feAv spores with rounded angles, 

 If my determination of these specimens is correct, K. Pennyi is nearly related on the 

 one side with K. reniformis, on the other with A', ornata Post. et Rupr. It is distingui-
