I have found the lateral line complete to the root of the tail, 
and then furnished with 41-42 spines. In other instances it 
breaks off at a greater or smaller distance from the tail some- 
times hardly reaching the posterior end of the anal or not 
even so far with only 30 spines. 'The development of the 
other spines and tubercles varies also a good deal both in 
number and size, but none showed any tubercles at the base 
of the anal fin. 
As cam be understood from the variation of the compara- 
tive measurements of the dorsal and anal fins related above 
the number of rays is variable as can also be seen from the 
following table:

Centridermichthys hamatus is cireumpolar, and seems to 
be one of the most common fishes round Spitzbergen, and ex- 
tends its distribution so far as the expedition reached north- 
east of the Seven Islands. At King Charles Land it is also 
quite numerous, but has of course not been recorded before 
from that place as zoological investigations have not been 
carried on there before. The same is also the case with White 
Island.

This rare fish was only obtained twice (4 specimens in

damaged by the dredge. . The largest is however in good
