PYCNOGONIDA.

Distribution. The species is rather widely spread; it was first known from the Kara Sea 

 (Hansen), but is found to the south far down in the Norwegian Sea, and to the west it has been 

 taken quite up in the Baffin's Bay.

Idem, Pycnogonidea, 1891, p. 78. PI. VIII. Fig. i, i a-i. 



Occurrence. The Ingolf-stations are: 7, 36, and 138; accordingly it is taken in the southern 

 part of the Atlantic, towards Iceland, and in the Davis Strait; the depths from 362 600 fath. 



Distribution. The species had hitherto only been taken by Sars, chiefly along the western 

 coast of Norway until Lofoden, and in the sea between the Finmark and Beeren Eiland, Pycnogonidea, 

 1891, p. 80, so that the Ingolf shows it to be considerably wider spread as well to the south as 

 to the west.

Nymphon macrum Wilson, Pycnog. New-Engl. Adjac. Wat, 1878, p. 487, PI. IV. Fig. 21 23. 

 Sars, Pycnogonidea, 1891, p. 89. PI. IX. Fig. 2, 2 a-g. 



Occurrence. The Ingolf-stations are: 25, 27, 32, 33, 35, 81, all in the Davis Strait and the 

 northernmost part of the Atlantic, S. W. of Iceland. The depths were most frequently between 318 

 and 582 fath. 



Previously it was found at the Zoological Museum from the Denmark Strait, 66 20' Lat. N., 

 25 12' Long. W., 96 fath. (Wandel). 



Distribution. Sars thinks the species to be originally arctic, because, besides occurring 

 between the Finmark and Beeren Eiland, it has also been taken at the eastern coast of North America 

 (Wilson); with this statement agrees also its occurrence in the Denmark Strait and the Davis Strait, 

 from where it has passed a little towards the south, into the Atlantic.

 Chaetonymphon macrouyx Sars, Pycnogonidea, 1891, p.m. PI. XII. Fig. 2, 2 a-k. 



Occurrence. The Ingolf-stations are: 2, 4, 101, 103, 105, 116, 138, 139, 140, 141, all situated 

 inside the southern and western parts of the Norwegian Sea, from the Faroe Islands quite to Jan 

 Mayen. The depths were 262 702 fath. It was found in great numbers, most frequently together 

 with IV. robitstum. 



Distribution. The species is found widely spread, from the Kara Sea down along the coast 

 of Norway to the Faroe Islands, but hitherto it has not been taken farther west than the western 

 part of the Norwegian Sea.
