. The Danish Ingolf-Expedition. Scientific expeditions; Arctic Ocean. COPEPODA 221 The rosfruiii has the basal portion lono; and rather slender, and is divided into two rather short branches, which each possesses a ver)- short tooth; the whole structure is completely like Scott's fig. 4, PI. XXVII. The crista is scarcely different from that of the female. The fifth thoracic tergite has near the dorsal margin a distinct slender tooth, almost reaching the middle of the first genital somite. The abdomen (text-fig. 72 a) is like that of the preceding species, but the lateral process of the first genital somite is less prominent. The antenmilac as well as the oral appendages are scarcely different from those of S. Thorii (text-fig. 72 b); the natatory legs do not differ from those of the females. The right endopodite of pes V (text-fig. 72 c) is very short, and consists of three segments, which are indistinctly separated; the second segment is the longest, and the third one is a short conical process bearing a slender seta. The first outer segment is long, and distinctly widened out terminally, where it medially possesses 3 expansions anteriorly and a single more prominent outer one posteriorly; the second outer segment is comparatively short, and, outwards, convex with a terminal expansion, and the third one is short, rounded, with a single spine. The described terminal parts of the right exopodite form a clasping organ (text-fig. 72 c—d). The two cylindric basal segments of tlie left leg (text-fig. 72 e) have each a basal rounded process as seen in figure; the third basipodite has an inner terminal one as well. The left endopodite consists of two segments, of which the one is rather short and rounded with distal process, while the other has two diverging processes, of which the one is axeshaped. The left exo- podite consists of a short basal segment and a longer distal one, inwards excavated and enlarged towards end; the inner margin of this is terminally and posteri
