Occurrence. — Along the whole coast of Finmark this species is very 

 frequently met with, in moderate depths, from 15 to 50 fathoms. The south- 

 ernmost place, where I have found it, is at Apelvser, Namdal. Off the west 

 and south coasts of Norway, on the other hand, I have never met with it. 



Distribution. — Arctic Ocean, widely distributed: Greenland (Hansen), 

 Iceland (Torell), Spitsbergen (Norw. North Atl. Exp.), the Murman coast 

 (Jarzynsky), the Siberian Polar Sea (Stuxberg), Labrador (Sidn. Smith).

Body comparatively less strongly built than in F. lynceus, though 

 rather tumid in the female. Cephalon produced anteriorly in a similar manner 

 to that in the above-named species, the frontal part being however far less 

 tumified, and scarcely extending to the end of the basal joint of the superior 

 antennae; lateral corners somewhat less produced. Coxal plates comparatively 

 smaller than in the type species, and, in female, scarcely deeper than the body, 

 1st pair rather broad, and nearly transversely truncated at the tip. Eyes much 

 smaller than in P. lynceus, placed close together at the tip of the front, pig- 

 ment bright red. Superior antennae in female reaching a little beyond the 

 peduncle of the inferior, 1st peduncular joint scarcely longer than the 2nd, 

 flagellum shorter than the peduncle, and composed of about 8 articulations; 

 those in adult male more elongated, with the flagellum nearly twice as long 

 as the peduncle, and composed of 11 articulations, the 7 inner ones being 

 rather thick, and densely clothed with delicate sensory bristles. Inferior 

 antennae in female about twice as long as the superior, penultimate joint of 

 the peduncle rather large and densely setous, last joint very narrow, linear, 

 flagellum about the length of the peduncle; those of adult male extremely 

 elongated and slender, attaining the length of the whole body, the last 2 joints of 

 the peduncle without the usual setae, but clothed along their anterior edges with 

 small tufts of sensory bristles, flagellum very slender and filiform. Anterior 

 gnathopoda about the length of the posterior, basal joint considerably dilated 

 in the middle, nearly fusiform in outline, propodos oblong oval, about 3 times 

 as long as it is broad, palm rather arched, and scarcely longer than the hind 

 margin. Posterior gnathopoda nearly as in P. lynceus. Pereiopoda consider- 

 ably more slender than in that species, with the dactylus very long and 

 falciform; basal joint of last pair less dilated. Last pair of uropoda with
