CRUSTACEA COPEPODA. II. 21 
Occurrence. — Not taken by the “Ingolf’’, but by Dr. Th. Mortensen, June 20, 1899. 
Feeroes: 16 miles East to South off Nolsé, 80 fathoms; 1 female. 
Distribution. — Recorded from Risér, south coast of Norway, about 50 fathoms, and from Chri- 
stiania Fjord near Drébak (G. O. Sars). Furthermore gathered in the Firth of Clyde (T. Scott) and at Triest, 
on Eunice Claparédi (Kurz). 
Selioides Levinsen. 
This very interesting genus I refer to the Cyclopoidea, as it in various features is more related to 
this than to any of the following divisions. Only a single species is known.

Levinsen’s description (in Danish) is good, and his figures sufficient, but his interpretation of some 
of the appendages is wrong. What he describes as a plate-shaped part situated behind each mandible and 
equipped on the free margin with a minute, oblong-oval knot and three spines is in reality a protruding 
maxillula; a little more behind the two-jointed very robust maxille are seen, named maxillipeds by Levinsen. 
Furthermore he says that the abdomen has 3 pairs of limbs; what he names the abdomen is essentially the 
trunk, and what he considers to be the second pair of limbs is in reality the maxillipeds, which lie near the 
median line and in the female far more backwards than the first pair of thoracic legs, while in the male they 
are at least as far forwards as first legs, the latter pair being in the male articulated at the outer proximal 
angle of the maxillipeds. Already in 1886 I proposed this interpretation and besides pointed out the existence 
of three pairs of small, ventral and transverse chitinized thickenings, in all probability being the vestiges of 
the three posterior pairs of thoracic legs. 
Occurrence. — Taken by the “Ingolf” at a single station. 
Denmark Strait: Stat. 96: Lat. 65°24’ N., Long. 29°00’ W., 735 fathoms, temp. 1°2. 1 female, situ- 
ated above one of the parapodia of Harmothoé nodosa. 
At West Greenland this species has been taken at three places. It was gathered at Kekertak, Torssu- 
katek’s Ice-Fjord, 135—140 fath., on Nychia cirrosa, Aug. 31, 1870 by Dr. Oberg (Riks-Museum, Stock- 
holm). At Egedesminde (Lat. 68°42’ N.) it was discovered by Mag. sc. M. Levinsen on Harmothoé imbricata, 
and the majority of the considerable number of specimens was found in stomachs of Cottus scorpio. At Godt- 
haab (Lat. 64°11’ N.) a single juvenile female was secured by Capt. Ryder. 
Distribution. — The Kara Sea, 65 fath., 1 female on Harmothoé imbricata (H. J. Hansen). 
Division Monstrilloida. 
Of this small but extremely interesting division only a single species has hitherto been found within 
the “Ingolf”’ area, but it may in all probability be possible in the future to gather a few forms near the Feeroes 
and south of Iceland.
