. The Danish Ingolf-expedition. Marine animals -- Arctic regions; Scientific expeditions; Arctic regions. Kit Head of Lycodes p/alyr/nniis, .seen from above, the side and from underneath. X i. preojjerculum. The tube-shaped nostrils are situated a little above the interspace between the two foremost grooves of the upper jaw. The dorsal fin begins almost over the posterior third of the pectoral when extended back- wards, at a distance from the snout equal to 26,3 % of the total length. Both this fin and the anal fin are covered b\' a thick skin, so that it is diffictdt to count the rays; I have reckoned the number to be 99 in the dorsal fin, <S2 in the anal, half of the tail fin being as usual reckoned in each. The pectoral, which contains 15 rays, is of an oblique quadrangular form; its length is ii,3'7o of the total length. The ventral fins are short (almost of the same length as the space between the eyes) and placed very close to one another. Of scales no trace can be observed; whether this naked condition is a constant feature or only due to the small size of the specimen, can naturally not be decided with certainty, but the scab- covering is generally far advanced in development at a length of ca. 150 nnu. in the Lycodes which are on the whole provided with scales, so that the first alternative is the most probable. The \-entral branch of the lateral line is only distinct in its course down towards the anus. It begins on the neck, forms a small arch over the free flap of the gill-cover and inclines thereafter down towards the anus, but becomes already indistinct over the anus. Along the median line of the side a tolerably distinct line with not a few pores is to be seen under the lens; the pores are some- what far apart in front but closer together posteriorly. The colour is uniformly a ruddy brown-gra\-, the fins and underside of the head lighter, dirty gra\'; the dark peritoneum shows through the belly. Distribution. A single specimen ($) was taken by the
