I cannot follow Wilson, when he not only incorporates the .\'. iiiixfidii of Kro_\-er, bnt also 

 the ^A". brevitarse of the same anthor into the species ,\'. grossipes of (J. Fabricins. 



Occurrence. The Ingolf-stations are 95 and 96, in the middle of the Denmark vStrait. The 

 depths were 752 and 735 fath., and the bottom temperatnres 2 ,1 and 1 ,2. 



Dis tri bntion. The species was formerly onl\- known from Greenland (Kroyer), and one 

 specimen from the straits of Alatotschkin Sharr, on a depth of only 10 — 15 fath.

Occurrence. The Ingolf-stations are 93, 94, and 127, the two first in the Denmark Strait, 

 towards the coast of Greenland, the last one in the Cyreenland Sea, not far from the northern coast 

 of Iceland. The depth was in the Denmark Strait 204 and 767 fath., in the Greenland Sea 

 only 44 fath. 



Further it is found at the Zoological ?tluseum from the Davis vStrait: 65-35' Lat- X. 54' 50' 

 Long. W., 80 fath. ( Fylla , Holm), and 66" 32' Lat. X. 55 34' Long. W., 100 fath. (idem). 



Distribution. Sars, Pycnogonidea, 1S91, p. 97, regards it as a genuine arctic species, from 

 the sea between Beeren Eiland and Spitzbergen (Sars), the Barents Sea (Hoek), the Kara Sea and the 

 Davis Strait (Hansen), to which the Ingolf thus adds the .southmost parts of the Greenland Sea and 

 the Denmark Strait.

Occurrence. The Ingolf-stations 93, 138, and 143 show it to be taken as well in the Den- 

 mark Strait as in the southern part of the Norwegian Sea, at the first station at a depth of 767 fath., 

 while at the two last-named stations in the Xorwegian Sea the depths were respectively 471 fath. 

 and 388 fath. 



Previous to the Ingolf e.Kpedition it was found at the Zoological iMnsenm from a high degree of 

 latitude in the Denmark Strait: 65 39' Lat. X. 28 ' 26' Long. W., 553 fath., the bottom stones and shells
