A great number of specimens of this arctic species have been 

 collected at various localities, most abundantly in Danmarks Har- 

 bour. The form of the frond is somewhat variable, in some cases 

 of nearly orbicular outline, usually however more or less lobed and 

 often also undulated. Most of the specimens are devoid of basal 

 disc and have probably been so at the moment of dredging. Some 

 of the specimens, however, show well-developed basal discs mostly 

 attached to barnacles. Some of the specimens provided with basal 

 disc seem not to have been attached, when they were collected, as 

 is to be concluded from the form of the basal disc, its under face 

 not being plain but hollow^ by strong development of the border, 

 probably after its detachment from the substratum. The reason 

 why almost all the specimens are without basal disc may be in 

 some cases, that the plant has been torn away from its substratum, 

 leaving its basal part; I imagine however that most of the specimens 

 have been really loose-lying on the bottom. This is suggested by 

 the form of the frond and by the fact that most of the numerous 

 specimens from Danmarks Harbour have been dredged at a locality 

 where the bottom is soft. 



Some of the specimens agree fully with specimens referred by 

 J. Agardh to Kallymenia rosacea, which however is not specifically 

 distinct from Turnerella Pennyi, as stated by Børgesen and Jonsson 

 (1. c.) and as suspected already by J. Agardh (1. c.) 



The largest of the specimens contained in the collection mea- 

 sures 50 cm. in greatest diameter in a dried state. Some specimens 

 contain numerous cystocarps, partly ripe, partly empty. 



Loc. Along the East side of Koldewey Island, ca. 15 meters; oft' Cape 

 Bismarck; along Cape Bismarck Peninsula; Danmarks Havn, 7—11 meters, 

 soft bottom; oft" Baadskæret, 28 meters; the bay oft' Vesterdalen, 4—11 meters.

All the specimens of the collection belong to the subsp. inter- 

 rupta; they are well-developed; partly very broad, and up to 18 cm. 

 high. Nearly all the specimens have no basal portion and have
