as Plenties glaber. According to tliat &utlnoT the Paramphifhoe exigua of Goes 

 is identical with the present species. The same is evidently also the case 

 with Parapleustes gracilis of Buchholz, though Dr. Hansen seems inclined to 

 regard this form as identical with the above-described ParampJiithoe brevicorni* 

 G. 0. Sars. From the 2 succeeding species the present form is easily distin- 

 guishable, by the spiniform projection of the basal joint of the superior an- 

 tennae, as also by the structure of the gnathopoda. 



Occurrence. Off the whole coast of Finmark this species is very 

 frequently met with in rather shallow water among algae. Occasionally it 

 also occurs off the west coast of Norway, and according to Boeck also in the 

 Christianiafjord. 



Distribution. Greenland (Buchholz), Spitsbergen (Goes), Iceland 



(Torell), the Murman coast (Jarzynsky), Kattegat (Meinert).

Body comparatively less slender than in the preceding species, and 

 having the segments more sharply defined, though without any dorsal pro- 

 jections. Cephalon scarcely exceeding in length the first 2 segments of meso- 

 some combined, rostral projection very small, lateral corners angular at the 

 tip, postantennal ones but very little produced. Anterior pairs of coxal 

 plates nearly as in the preceding species, except that the dentiform projection 

 at the infero-posteal corners is nearly obsolete, 4th pair narrowly truncated 

 at the tip, and having the posterior edge below the emargination rather 

 oblique; the 2 succeeding pairs with the posterior lobe much deeper than the 

 anterior. Last pair of epimeral plates of metasome not produced at the 

 lateral corners, which are obtuse-angled. Eyes not very large, reniform, 

 pigment bright red. Superior antennee not quite as long as in P. glaber, 1st 

 joint of the peduncle without any spiniform projection, and scarcely longer 

 than the other 2 combined, flagellum about 3 times as long as the peduncle. 

 Inferior antennae scarcely more than half as long as the superior, the 2 outer 

 joints of the peduncle nearly equal-sized, flagellum not nearly twice as long 

 as the peduncle. Anterior gnathopoda rather slender, with the carpus com- 

 paratively large, nearly as long as the propodos, and having, below, a broad 

 setous expansion, propodos rather narrow at the base, and slightly widening 

 clistally, palm much shorter than the hind margin and imperfectly defined
