This indicates, that the breeding season has a considerable extent, 
commencing in the spring, reaching a maximum in the late sum- 
mer, and probably ceasing in the autumn, no grown up individ- 
uals being found after September, even in fairly considerable depth. 
It is possible, however, that in the very deep water the breed- 
ing is continued into the winter, the small specimens found in the 
spring being the offspring of these winter-spawning individuals. 
Also in the fjords the percentage number of mature specimens 
increases with the. depth. Particularly interesting in this regard 
are the stations 171 and 172 -in the Umanak Fjord. At stat 171 
(800 m wire) 21 %o of the individuals were mature; a few even 
belonged to group Ill. At stat. 172 (450 m wire) only 6 %o were 
mature; they all belonged to group Il. 
According to the experiences from the open sea, that the breed- 
ing takes place mainly in the deep strata, we cannot expect that 
the fjords, the depth of which is rarely more than 300—400 m, 
never more than about 700 m, will present favorable conditions 
for the breeding of this species, and the facts confirm this appre- 
hension. The whole of the material from the inlets is from July—— 
August. Mature specimens were only found in the deep strata, 
and even there in small numbers in spite of the fact, that 
these months seem to be the time of maximal breeding in the 
open sea. The percentage number of mature individuals (group Il 
and older) at the various stations in the inlets are as follows: 
Umanak Fjord (the deepest of the fjords), stat. 171, 800 m wire, 
21 %0; stat. 172, 450 m wire, 6 0. — Disco Bay, stat. 124, 
150 m wire, 0 ?/o "). — At Northern Storø, stat. 503, 250 m 
wire, 0 0. — Bredefjord, stat. 545, 325 and 400 m wire, ca. 10 
fo. — Skovfjord, stat. 583, 350 m wire; 5 "/0v. 
This does not confirm the apprehension of Ritter-Zåhony 
(1910, compare Vanhåffen 1897), that a migration towards the 
Coast takes place at the breeding season. From the experiences, 
mentioned above, we must rather think, that this species has its 
Natural place of living over the deep water during the whole 
of its life-period, the breeding taking place in very deep water, 
") From stat. 196 d only 4 specimens have been preserved, two of which 
belong to group II.
