than normally; we know that such cases may really happen, young 
individuals being found at every season of the year. 
The species has been taken at almost all the pelagic stations 
of the "Tjalfe" Expedition, but only from comparatively few stations 
has the material been preserved. I have measured the preserved 
specimens and examined the stage of development of the gonads. The 
result will be seen in the synoptic table. — It would be better to 
exclude the first five stations, which are from the Irminger Sea. — 
In June and, especially, in July we find the greater number to be 
large mature individuals. It is probable, therefore, that the breeding 
takes place mainly in July, the old individuals dying away after- 
wards. Then, in September we mainly find small specimens with- 
out any trace of gonads. The few specimens with gonads in the 
form of fine points or a little prolonged are, I suppose, the young 
of individuals breeding earlier than normally. — During the winter 
they. only grow a little, though in May the average size is ob- 
viously larger, and the development of the gonads begins, the 
growth increasing largely at the same time. 
The species has been found in almost all samples from the 
upper layers of the water. It seems to have been less common 
in 1909 than in 1908.
