LYCODIN.^;. 



The dorsal fin begins at a distance from the snont equal to 29,6 — 33,7 "/o of the total length; 

 it contains 91 — 97 ra)s, the anal fin 73 -78 rays. The \-entral fins are small (almost of the same 

 length as or even shorter than the longitndinal diameter of the pnpil). The pectorals are relativel_\- 

 broad but short, their length being 9,6 — 11",, of the total length or ahvays less than the distance be- 

 tween the snout and the posterior margin of the eye; the\- contain (19)20—22 rays, of which the lower 

 project at their points from the connecting skin. 



The scales extend from the end of the tail more or less far forward on the sides of the bodv; 

 the covering tends to a point in front like a wedge, leaving the side of the back and belly naked for 

 some distance; there are no scales on the fins, or in any case onlv on the posterior half of the dorsal 

 fin, along the base. In the uniformly coloured or weakly banded form, the scaly covering is subject 

 to great variation in regard to distribution in part independentlv of tlie age of tlie individuals, it seems. 

 In the t\'pe-specimen, which is 445 mm. long, the scaly covering extends forward scarcely to a point 

 which lies directl)' over the origin of the anal fin. In the second largest (365 mm.) on the other hand, 

 the scales reach to a point at the tip of the flattened pectoral and have thus attained the greatest 

 extension known as yet for the species. In the 335 nnn. specimen (Tab. X, fig. i b) and that of 180 mm. 

 (Tab. X, fig. I a) the scaly covering extends forward a little in front of the anus, in Collett's speci- 

 men from Spitzbergen (128 mm. long) just a trifle in front of the anus. The specimens present of the 



distinctly banded variety have a much more regular distribution of the 

 scales (Tab. IX, fig. i b, c, d, e). In 3 specimens of 280, 218 and 180 nnn. 

 tlie scaly covering extends forward like a wedge to a point, which lies 

 directly over the anus, whilst in 5 specimens of 250, 197, 180, 161 and 

 129 mm. it stops at a short distance behind the anus. 



The lateral line begins over the gill-cover, forms an arch over 

 the shoulder and courses from there along the middle of the bod)'. On 

 the foremost part of the trunk in well-preserved specimens, a shorter or 

 longer series of pores is present above the lateral line, with wide inter- 

 spaces and without forming any true lateral line. 



Colour. The present species occurs in two colour-varieties, it 

 seems, namely, one uniformly coloured or with slighth- marked cross- 

 bands, the other with distinct cross-bands. — Those entirely imiform of 

 a gray-brown are: Reinhardt's type-specimen (445 mm. S) from Umanak;

from Jakobshavn. In the first of these, there are above the median 

 line 7 dark bands, 2 on the trunk and 5 on the tail, which again are somewhat lighter in the centre; 

 in the small sjDecimen, a similar number of somewhat more apparent bands are seen (Tab. X, fig. i a). —
