Naar man mindes, at hver station kun er et eneste 
skrabekast, maa station 192 med sine 85 arter, hvoraf 18 
arter er ny for Norges fauna og 10 arter ny for viden- 
skaben, siges at være en ganske mærkelig lokalitet. Sta- 
tion 173 b er ligeledes meget rig (59 arter). Derimod har 
station 195 en forholdsvis fattig fauna om end ogsaa denne 
station havde et rigt dyreliv (43 arter). Dette bekræfter 
forøvrigt, hvad professor Sars i ovennævnte arbeide om 
dyrelivet paa vore havbanker udtaler, at det særlig er af- 
heldet ud mod det store havdyb, som viser et paafaldende 
rigt dyreliv. 
En stor del af de paa station 173 b og station 192 
fundne mollusker var døde skaller og ganske paafaldende 
er det at se, hvor mange skaller af grundtvandsformer, 
der havde samlet sig paa disse forholdsvis store dyb. Bund- 
prøven fra station 192 bestaar ,,vesentlig af uorganiske 
dyrelevninger, sammenkittede ved brunt ler“ (Schmelek)*). 
Bunden er med andre ord en skjælbanke. Ikke saa faa 
skalrester har ogsaa et semifossilt udseende. Det er derfor 
ikke saa usandsynligt, at vi her har for os glaciale aflei- 
ninger. Efter vor formening foregaar der dog fremdeles 
en stor udskyllmg af døde skaller fra den ovenliggende, 
grundere del af banken. 
Station 1738 b, der havde bjerggrund, gav indtryk af 
at være en mere recent skjælbanke. 
Paa vedføiede kartskitse har vi angivet disse 3 sta- 
tioner. —

When we recollect that each station is only a single 
cast of the drag-net, it must be said that Station 192, with 
its 85 species, of which 18 are new to the Norwegian 
fauna, and 10 new to science, is quite a remarkably rich 
locality. Station 173b is also very rich (59 species). 
Station 195, on the other hand, has a comparatively poor 
fauna, although it possessed an abundance of animal life 
(43 species). This moreover confirms Professor Sars’s state- 
ment in his above-mentioned work on the animal life on 
the Norwegian ocean banks, that it is especially the slope 
towards the great depths that shows a strikingly abundant 
animal life. 
A large portion of the molluscs found at Stations 
173 b and 192 were empty shells, and it is quite remarkable 
how many shells of shallow-water forms had collected in 
these comparatively great depths. The bottom-sample from 
Station 192 consists ‘mainly of inorganic animal remains, 
cemented together with brown clay’ (Schmelck)'). In other 
words, the bottom is a shell-bank. Not a few of the 
shell-fragments have also a halffossilised appearance. It 
is therefore not improbable that we have here glacial de- 
posits. It is our opinion, however, that a great washing 
out of empty shells from the upper, shallower part of the 
bank, is still in progress. 
Station 173b, which had a rocky bottom, gave the 
impression of being a more recent shell-bank. 
On the accompanying sketch-map we have indicated 
these three stations.
