. The Danish Ingolf-expedition. Marine animals -- Arctic regions; Scientific expeditions; Arctic regions. 142 COPBPODA. Oped setigerous process inwards, and the second segment has a similar one at the base in addition to ones sitting in the middle as well as terminally (text-fig. 38 f). The mandibiilae and viaxilhilae do not show any features which were not mentioned in Giesbrecht's description. The viaxillae are very much like fig. 5 c of Ch. abyssalis. The third basipodite of the niaxillipcds, wliich is almost twice as long as the Basp. i 05 2 and distinctly three times as long as the Ri, has along the exterior margin almost from base to tip on the posterior surface a low transparent lamella with a distinct concavity in the middle; the fourth lobe of tlie second basipodite is placed posteriorly, and has a fairly long sensory lobe surrounded by slen- der hairs, in addition to three setae (text-fig. 38 g); anteriorly, and somewhat removed from the tip, a rounded protuberance is found in tlie second basi- podite, probably corre- sponding to that of E. cur- ticauda. The first pair of legs has the inner margin of the last basipodite slightly convex, as seen in text-fig. 38 h; the Se of Ri I has no accessory tooth in the second pair of legs, and no trace of it in the third and fourth pairs (text-fig. 381); the inner margin of the second basipodite in the fourth pair of legs is in most specimens completely smooth, but in some has one or two short stiff hairs corresponding to Giesbrecht's "sparlichen kurzen Spitzen". The glandular pores are like those of Undeuchcete. The elevation in front of the labrum is smooth and fairly well raised; along the posterior margin the labrum proper has as usual a median row of long and slender hairs divided into a right and a left part, and a lateral sliorter one, of more spine-shaped setae. The oral surface of the labrum (fig. 4 b) is like that of Undeuchate. The first group of tlie longitudinal series is placed obliquely, and c
