. The Danish Ingolf-Expedition. Scientific expeditions; Arctic Ocean. 74 LYCODIN^. The dorsal fin begins at a distance from the snout equal to 29,6—33,7% of the total length; it contains 91 — 97 rays, the anal fin 73—78 rays. The ventral fins are small (almost of the same length as or even shorter than the longitudinal diameter of the pupil). The pectorals are relatively broad but short, their length being 9,6—11*^0 of the total length or always less than the distance be- tween the snout and the posterior margin of the eye; they contain (19) 20—22 rays, of which the lower project at their poin

The scales extend from the end of the tail more or less far forward on the sides of the body; the co\'ering 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 only 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 independently of the age of the individuals, it seems. In the type-specimen, which is 445 mm. long, the scaly covering extends forward scarcely to a point which lies directly 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 mm. 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 distincth' 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 mm. the scalv covering extends forward like a wedge to a point, whiclr lies directly over the a
