from the dorsal colour. The latter is not (as in the male) sharply 

 distinguished from the colour of the belly, which is silvery-yellowish; 

 round the anus it is light-red, owing probably to the degree of 

 development of the sexual organs. The brownish-red colour of the 

 head also spreads out on the yellow iris without however (as in 

 the male) completely concealing this. The gill-cover has the colour 

 of the belly; behind it there is no large silvery and purple-red spot 

 (in contrast to the male). Just as in the male the dark posterior 

 margin of the caudal fin is broad and there is a great deal of dark 

 pigment round the caudal peduncle; it is also common to both 

 sexes, that the other fins only have pigment on the rays (in the 

 form of spots), and that the dark dorsal colour of the caudal region 

 is continued down on the light colour of the belly in the form of 

 characteristic tongues. 



A male of 148 mm (PI. XLIV, fig. 2) is distinguished from the 

 foregoing by the very black jaws, brownish-black head and back 

 colour (which covers the most of the latter). The gill-cover is blue- 

 black and there is a large silvery (and behind this a purple-red) 

 spot at the base of the pectorals. The dorsal colour is distinctly 

 marked off from the silvery belly, though it is continued (especially 

 on the abdomen) down over the latter in the form of more or less 

 broken, parallel tongues along the ribs. The caudal region has 

 silvery spots (isolated patches of the colour of the belly), which are 

 distinctly bounded by a blue-black ring and outside this by the 

 colour of the dorsum (all the statements of the colour are based on 

 observations and sketches of the living fish). 



Icelus hamatus Kr. 



Gadus saida and this species are the commonest fishes on the 

 coasts of North-East Greenland, where they were taken in quantity 

 in Danmarks Havn and neighbouring waters at a depth of ca. 

 2—40 m. Like Triglops pingelii it has a characteristic, bathymétrie 

 distribution with age, only the young (ca. 30— 40 mm) occur- 

 ring in the littoral region (soft bottom); both these and the 

 somewhat older (up to ca. 80 mm) are met with in the Laminaria 

 region; and in the Delesseria (or Lithotamnion) region we find only 

 the very large specimens (over ca. 80 mm), but then both on the 

 soft and hard bottom. Thus, though the young are in quantity one 

 of the most typical fishes of the littoral region, the adults are much 

 scarcer, even in their main region of distribution at a depth of ca. 

 10 m., but they nevertheless along with Triglops pingelii belong to 

 the most abundant bottom fishes. The fish taken were caught in 

 July— September 1906 and 1907; of these several (marked with (?)
