 Clyrlonia borcaliv, G. O. Sars, Oversigt af Xorges Crnstaceer I, p. 75, pi. 3 fig. 1- 



Cephalon more deep than long, with a pair of small tiiberculifbrm pro- 

 jections just above the insertions of the superior antennae. The latter about 

 half as long as the body, excepting the urosome; proximal joint of the 

 fiagellum serrated at both edges, more minutely at the superior one, its basal 

 portion somewhat more incrassated in the male than in the female and 

 densely hairy. Inferior antennae in male about as long as the body, last 

 joint of the peduncle very elongated, fiagellum 5 (5-articulate. Propodal joint 

 of 1st pair of gnathopoda shorter than the carpal joint, that of 2nd pair 

 about as long as the latter. Third pair of pereiopoda longer than the 4th; 

 basal joint serrated on both edges and jutting out at the end as an acumi- 

 nated process overhanging the ischial joint, propodal joint about half as long 

 as the carpal one. Last pair of pereiopoda scarcely half as long as the 

 penultimate one, basal joint about the length of the remainder part of the 

 leg. First pair of uropoda strongly denticulated on the inner edge, 

 exterior ramus both in this and the succeeding pair obsolete, that of the last 

 pair about as long as the basal portion. Telson acutely triangular. Body 

 very pellucid, with light red intestine and oral region, and with scattered 

 reddish pigmentary spots on the posterior division. Length S mm. 



Rewiirl-x. - The species established by Dr. Bovallius under the name 

 of Ti/ro Clansi is very nearly related to, if not identical with, the present 

 species, only differing by the 3rd pair of pereiopoda being somewhat shorter 

 and by the poor development of the propodal joint of these legs. In all 

 other respects, and especially in the structure of the urosome, with its several 

 appendages, it agrees exactly with the northern form. 



Occttrrrnce. I first detected this interesting Hyperid many years 

 ago at Lofoten. It occurred here only at very great depths from 200 to 

 300 fs. Subsequently I have met with this form also in two other localities 

 on our coast, viz., in the outer part of the Drontheimsfjord at Bejan, and in 

 the Christianiafjord at Hanko. Here also it was only procured from com- 

 paratively great depths (100150 fs.) by the aid of the dredge or a fine 

 hand-net rixed to the dredge rope at a short distance from the dredge.
