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

 White Sea') to the British Lsles and west of France (lyoire)^) 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— loofm., which agrees with the observations from the Faeroes 

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

") According to Collin (Dijmphna-Togtets zool.-bot. Udbytte, 18S6, p. 450) a very young specimen (ig"'"'. long) is 

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

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

 a verj' 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 from the coastal region with seaweed or ice-floes (Ver- 

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

 is in any case a mistake; it has not been taken at Greenland (cf. antea p. 48), nor at Spitzbergen (cf. Knipo witsch, Ann. 

 Musee zool. de I'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 Locard in his list: Les coquilles marines des cotes de France (1S92); in the same 

 author's Prodrome de Malacologie Fran<^ise, MoUusques marins (1886) numerous localities are given for it (p. 491).
