Zoogeographical Investigations in Southern Greenland. 367 
fauna, whereas judging from the depths given, it would seem rather 
to belong to the arctic deep. 
None of these Echinodermata are included in the material from 
the “Rink”’. 
Of Crustacea and Pycnogonida, none belonging to Groups 1 A and 
1 B were found; of those belonging to Group 1C, we have Stegocephalus 
inflatus, Neohela monstrosa, Aiginella spimosa, and Calathura brachiata. 
None of these, however, are truly arctic forms, as none of them are 
restricted to purely arctic conditions; the three first are found far to the 
south along the coast of Norway, (the two first into the Skagerak or 
even the Kattegat) while the last is even known from the Bay of Biscay.

(K. St., Danmark-Exp., p. 577; Conspectus p. 418. — Th. Mortensen, 
Danmark-Exp., p. 292; Conspectus p. 313). 
Of Malacostraca and Pycnogonida 70 species are mentioned 1. c. 
Of these, grown specimens of the followimg were taken by the “Rink’”?). 
x Munidopsis curvirostra 
Spirontocaris Lilljeborgu 
Pandalus borealis, with the larve of 
x Munida Bamffica (?, new to Greenland) 
x Pontophilus norvegicus 
x Pandalus propinquus, and the following spp. new to Greenland 
Caprella Rinkii (n. sp.) 
Eurycope producta 
Sealpellum Stroemii, besides 
? Saccopsis Terebellidis. 
Of Echinoderms, Tu. MorTeNSEN mentions in all 31 species, to 
which must be added the following six: 
Molpadia Blakei var. groenlandica 
Pteraster hastatus 
Ophiozona tjalfiana 
Ophiotjalfa vivipara 
Amphiura denticulata 
Ophiomyx serpentaria. 
Of these 37 Echinodermata the following are found in the “Rink”’ 
material: 
x Molpadia odlitica x Poraniomorpha hispida 
x Psolus valvatus x Pedicellaster typicus 
x Laetmogone violacea Pteraster hastatus 
x Astrogonium Parelii x Ophiacantha anomala 
1) % indicates that the species should be reckoned not merely as properly 
belonging to this zoogeographical group, but also as a true type form.
