obtusely rounded. The first 3 segments 41 of mesosome combined somewhat exceeding in length the 4th segment, which is about the same size as the 5th, both being almost twice as broad as they are long; last segment, as usual, considerably smaller. Metasome about the length of the last 2 segments of the mesosome combined, and distinctly narrowed distally. Eyes present, but very small, puncti- form, .occurring on the sides of the cephalosome, at some distance from the frontal margin. Superior antenna? with the last 2 joints of about equal length, and combined, not quite attaining the length of the basal one. Chelipeds very strong, hand oblong oval, not attaining twice the length of the carpus, fingers shorter than the palm, and not forcipate. Pereiopoda resembling in structure those in the preceding species, though perhaps somewhat less slender; carpal spine of the 5 posterior pairs comparatively larger, and more conspicaously cultriform. Pleo- poda (in female) wholly wanting. Uropoda of about same appearance as in P. forclpatus. Length of female 1.55 mm. PemarTfS. Though rather nearly allied to the preceding species, the present form may be easily distinguished by the somewhat different form of the cephalosome, the presence of distinct, though very small eyes, and by peds not being forcipate. the cheli- Occurrence. The only place where I have observed this form, is in the Va ranger Fjord at Vad so. It occurred here rather sparingly in a depth of 100- 120 fathoms. Out of Norway, it has not yet been recorded. 3.

Body very short and compact, scarcely more than 3 times as long as it is broad. Cephalosome scarcely exceeding in length the 3 anterior segments of mesosome combined, and strongly contracted in front, tip narrowly truncated. Free segments of mesosome about as in the 2 preceding species. Metasome gradually narrowed distally, with the terminal segment evenly rounded at the tip. Eyes wholly absent. Superior antennas very slender, considerably exceeding the cephalosome in length, last joint longer than the 2nd, and both combined, about the length of the basal one. Chelipeds exceedingly large, attaining nearly half the length of the body, hand very much elongated, with the fingers slender and narrow, considerably exceeding the palm in length, bat not forcipate. Pereiopoda rather slender, 1st pair with the propodal joint longer than the 2 preceding joints combined, and conically tapered, dactylus long and seti- 6 Crustacea.
