Hamingia arctica Danielssen and Koren 1881. 

 Hamingia glacialis Horst 1881. 



Distribution in General: 



As I ha ve not had the opportunity of investigating this species I am unable 

 to report any »Habitat» and with regard to the general distribution of the species, 

 I am reduced to relying upon the statements of my predecessors. To judge from the 

 below-mentioned localities its dispersion does not seem to be inconsiderable in the 

 northern seas. 



Danielssen and Koren (1881) have obtained a single specimen from 72° 27' n. 

 — 20° 51' e., sabnlous clay, 191 fms. — Horst (1881) has examined two specimens 

 from 74° 10' n.— 23° 20' e., 220 fms. and from 74° 16' n.-29° 47' e., 192 fms. — 

 Skorikow (1901) has examined several specimens brought home from the Murman 

 Sea. — Levinsen (1883) reports it from Iceland and Ray Lankester (1883) has in- 

 vestigated two samples from Lervik, at the mouth of Hardanger Fjord. 



According to Sluiter (1902) a species very nearly related, Hamingia sibogse, 

 has been dredged up in the Indian Archipelago; 5° 44' 7" s.— 126° 27' 3" e., 4391 m. 



Bonellia viridis Rolando 1821. 



Pl. II. figs. 14—15. 



Habitat : 



Norway: Trondhjem Fjord, Rödberg, 90 — 100 m., shells and stones (Östergren), 

 (Mus. L.), 2 sps. - - Bergen: By Fjord and Hjelte Fjord, 60—100 fms. (Östergren), 

 (Mus. Ups.), 4 sps.; Biskopshavn, 40—50 fms. (Mus. Chr.), 5 sps.; Mänger (Mus. Chr.), 

 2 sps.; Kors Fjord and Bergen Fjord (Koren and Danielssen 1875 and 1877); Dröbak 

 (Mus. Chr.). West coast of Sweden: Koster Fjord, 50—90 fms. (June 1893, T. Ek- 

 man), 1 sp. 



Distribution in General: 



If we can take it for granted that the various authors are right in their sta- 

 tements, the extensiveness of the distribution of Bonellia viridis appears rather stränge. 

 It has been reported from the following localities: Norway: Rödberg in the Trond- 

 hjem Fjord (Norman 1894), Bergen Fjord, Kors Fjord (Danielssen and Koren 

 1875 and 1977), Dyveholmen on the West coast of Norway (Shipley 1899). Sluiter 

 (1902) reports it from Terceira (Azores Is). Singularly enough, it does not seem to 

 have been obtained at the coasts of Denmark and the British Isles nor at the At- 

 lantic coast of France. In the Mediterranean and Adriatic, on the contrary, it is
