The o-group. 
This group is only caught accidentally and in some few localities 
and then always by the trawl, though, as stated before, the trawl only 
took with certainty such as were down to a length of 10 cm. The 
number of individuals caught is also very small; only the two samples 
from Heligoland Bay (Stats. 81 and 82) display a considerable amount 
of individuals, viz: 168 and 95. 
The material from the different localities is as follows:
