Habitat: 



West Greenland: Proven, 16 — 40 fms, rocks, 2 sps (1861 Torell); Upernivik, 

 130 fms, 1 sp (1870 Öberg). 



General Distribution. 



Cnemidocarpa finmarkiensis has been reported from a few localities only : 

 the northern coast of Norway: from Hammerfest; Tromsö, 2 sps (Kiaer 1893); 

 Tromsösund, 20 — 30 m, 1 sp; Kongsfjord, 70 — 90 m, many sps (Bjerkan 1908); the 

 Murman coast (Redikorzew 1908); the east coast of N. America 45° 29' N — 55° 24' 

 W, 1 sp (Van Name 1912). 



Remarks. 



Cnemidocarpa finmarkiensis is a rare form; only a small number of specimens 

 has hitherto been collected. Man}' of them have been dredged in Kongsfjord, Nor- 

 way (ef. Bjerkan 1. c). It is found in the Arctic region but chiefly in the Boreo- 

 aretie mixture zone. As appears from the above, its range of distribution comprises 

 West Greenland, the Murman coast, northern Norway, and the east coast of N. 

 America. 



Styela joannae Herdman and Styela stimpsoni Ritter, which have been reported 

 from the west coast of North America, Puget Sound, are no doubt closely allied to 

 C. finmarkiensis. If we compare the descriptions of the three species the differences 

 between them do not seem to be of great importance. Huntsman (1912) is of 

 opinion that S. joannae Herdman is synonymous with S. stimpsoni Ritter and accord- 

 ing to Bjerkan (1. c.) there are reasons for supposing that even C. finmarkiensis would 

 be synon}'mous with S. stimpsoni. Ii further comparative studies should confirm 

 the supposition that the three forms are identical, which appears most probable, 

 the range of the species would comprise even the north-eastern part of the Pacific 

 Ocean, where C. joannae is common off the coast of British Columbia and occurs 

 abundantly in Puget Sound (Huntsman 1912). Further investigations of the syno- 

 nomy and distribution of this in teresting species will surely be of the highest im- 

 portance. 



The three preserved specimens at my disposition are of a yellowish-white colour; 

 when alive, the species is said to be blood-red. 



C. finmarkiensis occurs on härd bottoms, even corals; it is attached to stones 

 or shells. It has been dredged at a depth varying from 20 m to 234 m.
