The asperities on the posterior side of the pectoral rays of 
the male specimens seem to be less developed than in Scandi- 
navian specimens, and on the ventral rays not at all. But 
the males were more richly provided with spiny tubercles 
scattered over the sides of the body than the females. The 
variation of this species is plainly shown by MALMGREN, LÖT- 
KEN, SMITT a. 0., but it might be some characteristics that 
can defend LÖTKEN's »var. grönlandica» as an arctic variety, 
although in most cases all intergrading stages may be found. 
Cottus scorpius is widely distributed in arctic regions, 
and although this expedition only found it at the West-coast 
of Spitzbergen, it has been previously recorded as well from 
the fiords of the west and northwest coast, as from Hin- 
lopen Strait.

1 specimen NE. from the Seven Islands 81” 14' N., 2250' E.: depth 150 m., 
gray clay; temperature + 2” C. ?0/g 98. 
The total length of this specimen was 73 mm. There 
were 9 plates between the anal opening and the anal fin. 
Some comparative measurements are given below:

These measurements agree, on the whole, very well with 
the measurements taken by SMITT (1. ce. p. 207) of specimens 
of this species from Greenland. But they agree better with 
the measurements of a larger specimen (total length 162 mm.) 
than with those of a specimen of nearly the same size. The 
specimen from Spitzbergen thus represents a little more ad- 
vanced form, as far as can be judged from one specimen.
