attain the double depth of the body and have th< j posterior corners drawn out 

 to an acute angle; 5th pair considerably broader than it is deep. First pair 

 of epimeral plates of the metasome produced anteriorly to a short tooth like 

 projection; last pair having the posterior angle drawn out to a short uptur- 

 ned point, above which there is a small sinus defining the latter from a convex 

 expansion of the posterior edge. Eyes reniform, much larger in male than in 

 female, pigment deep red. Superior antennae of female about l /a the length 

 of the body, in male considerably longer, 1st joint of the peduncle very thick 

 and masive jutting out at the end interiorly as a short spimforni projection. 

 the Mother joints very short; fiagellum furnished in both sexes on the posterior 

 edge with a somewhat alternating series of rather large calceolse, accessory 

 appendage very slender and composed of about 10 articulations. Inferior 

 antennas in female a little, in male considerably, longer than the superior, 

 fiagellum in both sexes furnished anteriorly with a row of similar calceolse as 

 on the latter. Anterior gnathopoda with the propodos about as long as the 

 carpus but much narrower, dactylus evenly curved and armed at the base 

 with a dense bunch of delicate spinules. Posterior gnathopoda nearly twice 

 the length of the anterior, propodal joint oval, half as long as the carpal 

 joint and not at all produced at the tip. Last pair of pereiopoda almost twice 

 the length of the 3rd. hast pair of uropoda with the rami much longer than 

 the basal part, outer one the longer and having a distinct terminal joint. 

 Telson twice as long as broad, cleft beyond the middle, each lobe bearing a 

 small apical denticle. Colour light greenish, oral region and urosome partly 

 tinged with crimson. Length 17 mm. 



PifniarJcs. - The present very handsome species is chiefly distinguished 

 by the peculiar supply on the antenna! nagella in both sexes of numerous 

 rather large colceolse, a character which usually is only particular to the 

 male sex. Moreover the spiniform projection of the first joint of the 

 superior antenna?, and the peculiar form of the 1st and last pair of epimeral 

 plates of the metasome afford good distinctive characters. 



Occurrence. It has been found in several places on the west coast 

 of Norway: Manger, Stavangerfjord, Skudesnses, Bukken, Bejan, in moderate 

 depths, from 20 to 50 fathoms. Its most northern range seems to be the 

 Trondhj emsfj ord. 



Distrilittioii. Adriatic (Heller), gulf of Marseilles (Marion).
