stances I think it most suitable to unite all varieties under 
the main specific name Cyclogaster liparis TaN., but to use the 
name fabricii for the arctic variety which also seems to have 
a comparatively distinct coloration, and always is provided 
with a black peritoneum. 
This form is known to have a wide distribution in arctic 
regions from Greenland to the Kara Sea, but, of course, its 
presence round King Charles Land was not known before. 
There it however was very numerous and seemed to get on 
very well in spite of the low temperature of the water. 
11. Cyelogaster gelatinosus (PALLAS). 
1 specimen: SW. from South Cape of Spitzbergen 75'58' N., 13 18' E.: depth: 
390 m., gray clay: temperature + 2,7” 6. 1/9 98. 
This fish was not before recorded as belonging to the 
fauna of Spitzbergen, but it was known from Greenland, Jan 
Mayen, Beeren Eiland, the Kara-Sea and so far south as in 
the Faroe-Channel and between Arendal and Skagen. 
12. Cyelopterus (Eumicrotremus) spinosus FABRIOIUS. 
1 specimen: between Beeren Eiland and Hopen Eiland, 75” 49' N., 242 25' E.: 
depth: 80 m., rocky bottom: temperature — 1,42? 0. 21/5 98, 
1 > Icefiord, West Spitzbergen, 78 38' N., 14? 47' E.: depth 36 m., 
big stones with Lithothamnium. 19/7 98. Fragments of a larger 
specimen from the Icefiord, Cape Boheman, 78” 22 N., 19253 E.; 
depth 40—50 m. 
The first mentioned of these two specimens is quite nor- 
mal in its appearance, the other one, however, is the more 
strange looking in several respects. Both are of nearly the 
same size, the normal spinous one measuring in total length 
7 mm., the other one which is completely smooth is only 
),5 mm. shorter. The latter specimen also attracts the at- 
ention in having the first dorsal fin completely covered by 
he thick skin, so that the rays cannot be seen at all, except 
vt their extreme tips which make small prominences on the 
ipper edge. 
Through the kindness of Professor F. A': Smitt I have 
een allowed to make a comparison between this, as it seemed.
