Distribution. On the European side Modiola modiolus ranges from the "warm area" of the 

 White Sea 1 ) to the British Isles and west of France (Loire) 2 ) as also through the Kattegat into the 

 Sound and Belts; next, over the Faeroes to the coasts of Iceland. On the American side it is distrib- 

 uted from Labrador to North Carolina, and from Bering Sea to Japan and California. Jeffreys gives 

 the vertical distribution to be from o— 100 fin., which agrees with the observations from the Faeroes 

 and Iceland (cf. above); its true habitat is the Eaminaria region.

■) According to Collin (Dijmphna-Togtets zool.-bot. Udbytte, 1886, p. 450) a very young specimen (19 long) is 



said to have been taken in the Kara .Sea at 53 fin., but this case is isolated, and I doubt whether th( species really belongs 

 to this Sea. N. Knipo wi tsch also reports, that he has once obtained M.modiolus from the deep part of the White Sim. where 

 a very low temperature constantly prevails (the "cold area"), but he is of opinion, that it is not the normal home of the 

 species, but that the specimens have probably been carried out there front the coastal region with seaweed or ice floes 

 handl. d. Kais. Russ. Min. Gesellsch. Bd. 43, 1906, p. 275). — The circumpolarity of .V. modiolus, as maintained by some authors, 

 is in any case a mistake; it has not been taken at Greenland (cf. antea p. 4S), nor at Spitsbergen (cf Knipo witscta, Ann. 

 Musee zool. de l'Acad. Imp. St.-Petersbourg, VI, 1902, p. 119, note), nor on the north coast of Asia or in the waters N. of 

 arctic America. 



2) It has been forgotten by I.ocard in his list: I.es coquilles marines des cotes de France (1892 : in the same 

 author's Prodrome de Malacologie Franeaisc, Mollusques marins (1SS6) numerous localities are given for it p. 191)
