Montacuta substriata foreligger kun fra station 25, 
98 fv. og station 192, 649 fv. (døde skaller). 
Denne art, der stadig holder til paa piggerne af 
spatangus purpureus og undertiden ogsaa paa schizaster 
Jragilis, brissopsis lyrifera og echinocardium flavescens, er 
ret almindelig langs vor kyst op til Øxfjord i Vestfinmarken. 
Den er udbredt langs Europas vestkyst til Middelhavet og 
Adriaterhavet, hvor den forekommer paa cidares hystrix 
og spatangus meridionalis. I Kattegat gaar den ifølge 
Petersen mod syd til Kullen og Anholt. Den bathymetri- 
ske udbredelse er 5—722 fy. Fossil er den kjendt fra 
Norge, England og Italien.

Montacuta substriata was only found at Station 25, 
98 fathoms), and Station 192 (649 fathoms) (dead specimens). 
This species, which lives upon the spines of Spatan- 
gus purpureus, and sometimes on Schizaster fragilis, Briss- 
opsis lyrifera and Echinocardium flavescens, is quite com- 
mon along the Norwegian coast up to Øx Fjord in West 
Finmark. It is distributed along the western shores of 
Europe, in the Mediterranean and the Adriatic, where it 
is found upon Cdaris hystrix and Spatangus meridionalis. 
In the Kattegat, it extends, according to Petersen, south- 
wards as far as Anholt and Kullen.

Montacuta dawsoni fandtes i et par exemplarer i 
Advent Bay, 20—40 fv. Arten er tidligere kjendt fra 
Grønland, Spitsbergen, Skotland, Irlands vestkyst, Biskayer- 
bugten, Palermo og Norge, hvor Jeffreys har fundet den 
ved Drøbak, Friele ved Florø. Ifølge Petersen skal end- 
videre Collin have faaet den i Limfjorden. Den bathy- 
metriske udbredelse er 3—1750 fv. 
Two or three specimens of Montacuta dawsoni were 
found in Advent Bay (20—40 fathoms). The species had 
previously been found off Greenland, Spitsbergen, Scotland, 
the west coast of Ireland, in the Bay of Biscay, at Palermo, 
and in Norway by Jeffreys at Drøbak, and by Friele at 
Florø. According to Petersen, Collin has found it in Lim- 
Fjord. Its bathymetrical distribution is from 3 to 1750 
fathoms.

Denne art erholdtes i talrige exemplarer ved Beeren 
Eiland, 18 fy. Tidligere er den blot kjendt fra Novaja 
Semlja (Herzenstein) og det nordlige Norge, hvor den er 
tagen ved Vadsø, 10—25 fv., af saavel Verkriizen som 
Sars. Sars anfører, at han har modtaget exemplarer af 
denne art fra Jeffreys; nærmere lokalitetsangivelser for 
disse mangler dog.

A number of specimens of this species were found 
at Bear Island (18 fathoms). It is previously known only 
in Novaja Semlja (Herzenstein), and the north of Nor- 
way, where it was found at Vadsø (10—25 fathoms) by 
both Verkrizen and Sars. Sars states that he has re- 
ceived specimens of this species from Jeffreys, but there 
was no statement of the locality given.
