from Bredefjord, as the best investigated water. For their zoogeogra- 
phical importance vide infra (p. 366). 
In the algae belt, (Q—35 m.) the character forms were: 
Hyas coarctatus 
Sclerocrangon boreas 
Spirontocaris polaris 
Monoculodes latimanus 
Paramphithoé bicuspis 
Acanthonotosoma serratum 
— Fabric Pontogeneia inermis 
— turgida Ischyrocerus anguipes 
Mysis oculata Dulichia spinosissima 
— mixta Caprella septentrionalis 
Anonyx nugax Dajus Mysidis 
Balanus crenatus 
Sylon Hippolytes 
Strongylocentrotus droebachiensis. 
Onisimus Edwardsii 
Syrrhoé crenulata 
Paroediceros lynceus 
Of these again, however, some few species are seen to predominate 
over the rest viz; (No. 3) Hyas coarctatus, (No. 12) Spirontocaris Fabri- 
cli, (No. 16) Sp. turgida, (No. 17) Sp. polaris, but more especially (No. 63) 
Paramphithoé bicuspis, and (No. 68) Pontogeneia inermis. 
In H. J. Hansen, V. Gronlands Malakostraka 1887, the collections 
of several species present remarkable resemblance to some of the “Rink” 
stations, especially St. 61 (12.5—13 m.) even though the depths do not 
agree. Thus Horse has, from “Godthaab, deep water (abt. 40—60 
fath.); on Sertularia, with Metopa species” sent home the following 
species which are of interest in this connection: Amphilochus manudens, 
Metopa clypeata, M. borealis(?), M. longimana, M. Bruzelii, M. neglecta, 
M. longicornis, and Odius carinatus. 
In closed bays with decomposing weed, Nebalia bipes (No. 101) 
may almost be reckoned as a character form; in Julanehaab harbour 
over 550 specimens were taken at one time. 
Strongylocentrotus droebachiensis (No. 166) may be noted as a cha- 
racter form also for deep water (as far down as about 400m.) for the 
most part on rocky bottom. It would seem to be extremely common 
everywhere; in several places (though not in the area investigated, where 
the depth was generally too great) I have seen it in clear water at about 
10 m. depth, covering the bottom so thickly that the animals lay close 
up to one another; this we were frequently able to observe from 
the boat while under way for over five minutes at a time without 
a break. This applies, moreover, not merely to the fjord near the old 
Norse church, Kakortok, but also to several places between Ivigtut and 
Bredefjord. 
At depths from 35—200 m. only a very few species occur in great 
numbers; the only ones which can be said to do so are Ctenodiscus cris- 
patus, Amphiura Sundevalli, and Ophiacantha bidentata, but none of 
the bottom forms of Crustacea or Pycnogonida.
