the belly, but on the sides there are no scales in front of 
the beginning of the dorsal fin, and all along the base of the 
vertical fins there is a naked strip. Not less than 8 out of 
15 specimens from the Norwegian North Atlantic Expedition 
are said (1. ce. p. 101) to have had a similar disposition of 
the scales. 
The peritoneum is black and appendices pylorice are 
wanting. 
The total length of the specimen obtained is 260 mm. 
LÖTKEN has once expressed the supposition ! that Lycodes 
pallidus Corrert was likely to be regarded as a variety of 
L. frigidus Correrr. The author of both species acknow- 
ledges (1. c. p. 110) the similarity between them but says 
that L. pallidus of which only two specimens then were found 
has »somewhat larger» scales, »the pectorals and ventrals some- 
what shorter and the eyes smaller» than in L. frigidus. With 
the help of the measurements CorrEtt has recorded of these 
two »pallidus»-specimens and the measurements I have taken 
of the »frigidus»-specimen on hand, I have prepared the fol- 
lowing table showing the relation of the diameter of the eyes 
and the length of the pectoral and ventral fins to the total 
length:

This does not show any remarkable difference with regard 
to the diameter of the eyes which of course must be diminished 
with growing age. Neither does the relative length of the 
ventral fins offer any valuable distinction. The relation of 
the length of the pectoral fins in the larger »pallidus»-speci- 
men is however more conspicuous. If the length of the pec- 
toral fins of that individual is compared with the length of 
its head the difference is still more remarkable as the former 
measurement is not more than 43,5 24 of the latter, but in 
the other specimens the same relation is more than 50 2 as 
it, according to Corrertrt ought to be in young individuals of 
the L. frigidus, but it is diminished to less than 50 2 in older
