The fishes of the Danmark Expedition. 665 



At a length of ca. 50 mm the dorsum is uniformly brown-gray- 

 yellow, the belly and the fins lighter to quite white. At ca. 70 mm 

 (PI. XLV, fig. 1) there are alternating darker and lighter cross-bands, 

 fusing anteriorly into the dark-brown ground-colour of the head and 

 posteriorly into the light-brown of the tail. The cross-bands are 

 continued out on to the dorsal fin. The outer part of the pectorals 

 may now be bluish-brown and the anal fin often has a blue-black 

 outer margin (in the first 2 /3rds of its length). Specimens over ca. 

 100 m (PI. XLV, fig. 3) have the back and sides a leather-brown to 

 light reddish-brown ground-colour, whilst the ventral aspect is lighter 

 to almost skin-coloured. The light cross-bands are sometimes not 

 clear, being broken up into whitish spots (PI. XLV, fig. 2) (dark dots 

 appear, often united with characteristic markings in them), so that 

 the dark cross-bands grade evenly into them. The ground-colour 

 may be so dark, that the light cross-bands cannot be distinguished 

 in front, or only indistinctly, and not at all posteriorly, or the bands 

 may be very narrow and few. Both the light and dark cross-bands 

 are continued out on to the dorsal fin, where they often form 

 narrower or broader, quite white stripes; the last sometimes enclose 

 one or several dark-blue spots, producing "eyes" of varying size and 

 form ; they are situated in the front half of the dorsal fin at different 

 places in diff"erent fishes. The blue-black pigment on the outer 

 margin of the anal fin may be more or less distinct and connected, 

 longer or shorter; sometimes it is quite wanting. 



Qadus saida Lep. 



This species is exceedingly common both in the drift-ice off the 

 north-east coast of Greenland and in the waters investigated round 

 about Danmarks Havn. At the latter it was the most abundant fish, 

 occurring at sizes of ca. 50 to ca. 150 mm in swarms in the upper 

 layers in July — September, seeking their food among the icebergs. 

 In among the drift-ice and off the coast I have only taken a few 

 specimens of the size mentioned (one Ç of ca. 140 mm at 75°55'N.L., 

 14°35' W. L. 8. — 8. — 06, also the otoliths and bones of others from 

 the stomach of different birds (especially Larus eburneus) at about 

 the same time. Two $ of ca. 100 and ca. 125 mm were taken on 

 22.— 7.— 08 at 77° N. L., 18^2° W.L. 300 m). Very large specimens 

 (over ca. 200 mm) seem to occur more singly (Stormbugt May — June 

 1907—08). Lastly, a tiny larva of 9 mm was taken in Stormbugt 

 on 19.— 6.— 08 at a depth of 0—75 m (depth 207 m); along with the 

 earlier known ^ larvae (of 135 and 16 mm) taken in Hurry Inlet at
