Ianira tricornis, Diastylis Goodsiri, Chirodota laevis, Cucumaria calci- 
gera, Eupyrgus scaber, Stichaster albulus, Pedicellaster typicus, Hen- 
ricla sanguinolenta; their occurrence in the area investigated by the 
“Rink” does not, however, augment their area of distribution as formerly 
known to any essential degree, save in the case of Pedicellaster typicus, 
which had not previously been found S. of 663/° N. and which possibly 
belongs to the deep Atlantic fauna. 
3D. Aretic littoral species, found from Greenland to the eastward as. 
Siberia inelusive, and thus probably circumpolar, but not found in Nor- 
wegian waters S. of Finmark. 
(K. St., Danmark Exped. p. 588; K. St., Conspectus p. 420). 
To the 15 (13) Crustacea mentioned m the Danmark Exped. should 
be added Typhlotanais finmarchicus,(?) Leptognathia Sarsu, and possibly 
also Metopa leptocarpa, although this last-named species has been found 
S. of the area at Kristianssund in Norway. And in addition, Mysis oculata. 
Of Echinodermata, the following belong here: 
Myriotrochus Rinku Asterias panopla 
Psolus Fabricii Ophiura Sarsii 
Pteraster militaris Ophiocten sericeum 
Paraniomorpha tumida (also in Ophiopleura borealis 
deeper water) Gorgonocephalus arcticus 
Asterias Miilleri — eucnemis 
— ILincku Heliometra glacialis 
in addition to some also found in the North Pacific, viz 
Ctenodiscus crispatus 
Ophiopholis aculeata 
Amphiura Sundevalli. 
Of all these species the “Rink’’ material includes: 
Mysis oculata Asterias Miilleri 
Paroediceros lynceus Ophiura Sarsi 
Rkachotropis aculeata Ophiocten serium 
Amathilla pinguis Heliometra glacialis 
Dajus Mysidis Ctenodiscus crispatus 
Psolus Fabrici Ophiopholis aculeata 
Pteraster militaris Amphiura Sundevalli 
Poraniomorpha tumida 
3 E. Boreo-arctie species, found from America or Greenland to Spitz- 
bergen, but not N. of Siberia, and in Europe not south of Finmark. 
(K. Stephensen, Danmark Exped. p. 590; Conspectus p. 420). 
To this group belong 103 Crustacea and Pycnogonida mentioned 
in the Danmark Exped. and the Conspectus (Idotea metallica is erased, 
belonging in reality to the surface plankton; Leptognathia longiremis
