The first measured 75 mm, the others 38, 45 and 46 mm. Elsewhere 

 on the east coast this species is only known as adult and from 

 deeper water (Nathorst and Kolthoff; specimens of 61 — 245 mm 

 from 100 — 300 m)'; and it thus seems as if the young occurred in 

 much shallower water than the adults — a condition which also 

 agrees with what is known from Spitzbergen. 



Regarding the pigmentation of the fish in the living condition 

 I have made one coloured sketch and the following observations 

 (PI. XLV, fig. 4), Dark spots form cross-bands against the light 

 ground-colour; the spots are a shade darker than the ground-colour 

 in their centre; the margin is darker brown and the continuations 

 on the unpaired fins have a blue-black sheen. The pectorals and 

 ventrals as well as the unpaired fins are yellowish with light-red 

 stripes (especially posteriorly). The belly and under side of the head 

 are silvery; the iris golden with blue-black outer margin and pupil. 



Gymnelis viridis Fabr. 



I have taken this species in Stormbugt and Danmarks Havn 

 now and then in July — October 1906 and 07. It occurs here from 

 ca. 10 — ca. 40 m (Laminaria and Delesseria region) mainly on soft 

 bottom. Its main distribution is in the Delesseria region, 

 being the typical fish of this region, though much fewer in numbers 

 than Icelus hamatus and Triglops pingelii. Of the ca. 25 specimens 

 taken the smallest measured 54 mm, the largest 140 mm and it 

 seems as if the bathymétrie distribution according to age is less 

 marked here than in most of the fishes already mentioned. Else- 

 where it has been taken down to 100 m 2; it is thus a species which 

 is characteristic for not very deep water. 



In a female of 108 mm (Danmarks Havn. 4.— 9.— 07. 20— 30 m; 

 soft bottom) the abdomen was swollen from a few (ca. 5) very large 

 eggs (4 mm in diameter), which had a light-yellow colour. 



The colour in this species is extremely variable, as is well- 

 known; thus, among my ca. 25 specimens I have not found 2 which 

 were exactly alike. Characteristic for them all is, however, that 

 they assume to a high degree the colour of their surroundings 

 (red algae); along with Cottus quadricornis and Liparis liparis this 

 fish presents the finest examples of protective colouration according 

 to their respective habitats (namely, littoral, Laminaria and Delesseria 

 regions). Comparing all the specimens taken by me, I may make 

 the following general remarks, based on coloured sketches and 

 personal observations.
