Many specimens are present from the above named localities. Though no original specimens 

 of Fabricius exist in our museum there can be no doubt as to which species Fabricius has given the 

 name of "the long Nereid"; nor has Orsted felt any doubt about the identity of the species; he remarks, 

 1. c. p. 34, that "a great number of specimens had been sent down from the different places between 

 Auuanak and Frederikshaab." The species in question is, indeed, by far the most common species of Eteone 

 in Greenland, at any rate on the west coast; further it is a pronounced littoral species, which enters 

 entirely shallow water and easilv can be taken at eb-tide, and the behaviour of which is open to obser- 

 vation. Thus Fabricius gives an account of the comportment of it in the water. Malmgren indicates 

 that it is "hand infrequens" in a depth from 3 to 20 fms. The captures by "Tjalfe" prove that the 

 species also enters deeper water until c. 200 fms. 



Further it appears to me that Eteone longa is a particularly Arctic form; it is not known from 

 the coasts of the British Islands nor from the Atlantic coasts of France. Nor is it named in the list of 

 Norwegian polycha;ta in Bidenkap's Norges Annulata polychreta. Michaelsen states it from Danish
