more broad than deep. Last pair of epimeral plates of metasome obtusely 

 truncated at the lateral corners. First segment of urosome without any dor- 

 sal projection. Eyes of moderate size and nearly triangular in form, visual ele- 

 ments imperfectly developed, pigment reddish with a narrow opaque white 

 border. Superior antennae in female about twice the length of the cephalon, 

 1st joint of the peduncle large and thick, obtusely produced at the end an- 

 teriorly; nagellum scarcely exceeding half the length of the peduncle and 

 composed of 7 articulations, the 1st of which does not differ from the others 

 either in size or structure; accessory appendage about half the length of the 

 flagellum and 4- articulate. Same antennae in male having the 2 outer joints 

 of the peduncle and the base of the nagellum considerably more tumeficated 

 and provided with a dense brush of long sensitive bristles. Inferior antennae 

 in both sexes of the very same appearance, scarcely longer and much more 

 slender than the superior, the 3 outer joints of the peduncle nearly equal- 

 sized, flagellum composed of only 7 articulations. Anterior gnathopoda ex- 

 tremely slender, nearly styliform; propodos about the length of the carpus, 

 and gradually tapering distally; dactylus forming the direct continuation of 

 the propodos and provided with a strong secondary tooth and 2 slender setae. 

 Posterior gnathopoda somewhat more elongate than the anterior, but 

 less slender; propodos oblong, considerably exceeding the half length of the 

 carpus, outer part of the upper edge obliquely deflexed towards the small 

 dactylus and provided with several stiff bristles. Posterior pereiopoda suc- 

 cessively diminishing in length, basal joint of the 3rd pair forming below a very 

 slight laminar expansion, that of the 2 last pairs rather broad and rounded 

 quadrangular, exceeding in the last pair the length of the remainder part of 

 the leg. First pair of uropoda normal, 2nd pair considerably shorter, with 

 both rami simple mucronate, without spines. Last pair of uropoda so ex- 

 tremely small as easily to escape attention, rami much shorter than the 

 basal part, the outer the larger. Telson quite hidden between the lateral 

 parts of the last segment, scale-like, tip obtusely truncated. Colour bright 

 orange. Length of adult female 5 mm. 



Remarks. The present species is very nearly allied to K. compacta 

 (Stebbing) from the Kerguelen Islands, differing however in a few f points, 

 thus in the structure of the dactylus of the anterior gnathopoda, as also 

 in the shape of the basal joint of the 3rd pair of pereiopoda. 



Occurrence. - I have met with this remarkable form in 3 different 

 localities off the Norwegian coast, viz., at Hammerfest, Finmark, at Tjoto 

 on the coast of Nordland, and in the Hardangerfjord at Suiide. In all three 

 localities it occurred very sparingly at a depth of 100 150 fathoms.
