2 pairs comparatively narrow, with the distal edge conspicuously serrated 

 and bordered with long ciliated setae; the 2 succeeding pairs fully as deep as 

 the corresponding segments, and having likewise their distal edge serrated 

 and not at all emarginated; Htli pair with the anterior lobe terminating in a 

 narrowly rounded, deflexed lappet. Last pair of epimeral plates of metasome 

 of about same shape as those in P. Smitti, and having the posterior edge slightly 

 crenulated. Eyes very small, rounded, pigment red. Superior antenniE (in 

 female) scarcely exceeding Vs of the length of the body, 1st joint of the 

 peduncle a little shorter than the 2nd, flagellum not much longer than the 

 peduncle, and composed of 12 articulations only. Inferior antennae somewhat 

 longer than the superior, with the last joint of the peduncle but little 

 exceeding in length the penultimate one, flagellum about the length of those 

 joints combined. Anterior gnathopoda with tlie propodos fully as long as the 

 carpus, and oblong oval in form, having the palm imperfectly defined. 

 Posterior gnathopoda much more slender and elongated, witli the propodos 

 shorter than the carpus, and very slightly widening distally. The 2 anterior 

 pairs of pereiopoda normal ; the 3 posterior pairs moderately elongated, with 

 tlie propodal joint somewhat shorter than the carpal one, dactylns on tlie 

 last pair distinctly recurved; basal joint of antepenultimate pair produced 

 at the infero-posteal corner to a triangular projection, that of last pair very 

 much expanded, fully as broad as it is long, posterior edge strongly curved, 

 infero-posteal corner produced. Branchial lamella? distinctly lobular. Last 

 pair of uropoda of moderate length, and resembling those in F. Sicamnierdami. 

 Telson much longer than it is broad at the base, cleft extending nearly to 

 the base, and somewhat widening below, terminal lobes obliquely truncated 

 and each carrying the usual apical spinule together with a pair of small 

 hairs. Body dark yellowish gray, with a row of more or less distinct 

 orange-coloured patches along the back. Length of adult female scarcely 

 attaining 8 mm. 



BemarJcs. — This species, established by Boeck, somewhat resembles 

 the 2 preceding species, as to general appearance, being, however, easily 

 distinguishable by the comparatively higher body, the nearly horizontally 

 projecting rostrum, and the very small eyes. 



Occurrence. — The species is by no means rare off the Norwegian 

 coast. I have collected it, sometimes rather plentifully, in several places 

 both on the south and west coasts of Norway, as also in the Throndhj ems- 

 fjord, in depths ranging from 50 to 100 fathoms. It extends northwards 

 along the Nordland coast as far as Hasvig, west Finmark. Out of Norway 

 it has not yet been recorded.
