than ill the female, about as loiij,'- as the sixth joint, and the daw is conspicuously longer than 

 seventh joint. 



Abdomen much larger in proportion to the thorax than in the female, as long as the sum of 

 the four posterior thoracic segments; sixth segment (fig. 3 e) produced considerably backwards, much 

 longer than in the female and with the hind margin deeply emarginate, while the postero-lateral 

 angles are scarcely rounded. — Pleopods about as in the female P. abyssi, with moderately narrow 

 rami and the setse very long. — • Uropods (fig. 3 e) in the main as in the female, but a little more 

 slender, and one of the terminal setae of the endopod extremely long. 



Length of two males 1.25 and 1.40 mm. 



Occurrence. The "Ingolf" has taken this species at two localities. 



West Greenland: Inner end of Ameralik Fjord, Godthaab, muddy bottom; 43 specimens, 2 of 



which are adult males. 



North of Iceland: St. 128: Lat. 66° 50' N., Long. 20" 2' W., 194 fm., temp. 0.6°; 4 spec. 



P. forcipatus has besides been captured by other collectors at the following five localities within 

 our area. 



West Greenland: Karajok Fjord, ab. Lat. 70° 20' N.; many spec. Vanhoffen. 



East Iceland: Faskrud Fjord, 20—50 fm.; i spec. Mag. sc. R. Horring. 



East Greenland: Cape Dalton, Lat. 69° 24' N., 9— 11 fm.; 5 .spec. ($ and <S). IF' Amdrup Exp. 



— Turner Sound, Lat. 69" 44' N., 3 fm.; 8 spec. IF' Amdrup Exp. 



— Denmark Isl, Lat. 70° 27' N., Long. 26° 12' W., 10 fm., clay; 2 spec. Ryder Exp.

Distribution. This species has been established on specimens taken off Bohusliin in 50 — 60 

 and 120— T3ofm. In the Danish seas it has been taken four times, \-iz. two times in the south-western 

 Kattegat, 13 and 15 fm., and two times in Skager Rak, in 70 and 125 fin. (H. J. Hansen). According 

 to Sars it has been found along the whole Norwegian coast northwards about to Lat. 70'^ N. Furthermore 

 it was captured in Klosterelv Fjord, East Finmark, close upon the frontiers of Russia (A. M. Norman), 

 in the Barents Sea at Lat. 76° 26' N., Long. 60° 55' N., vertical pelagic haul from 30 to o meter (Stappers) 

 and at Northbrook I.sland, Franz Joseph Land, 10 fm. (Th. Scott). Finally it is known from some 

 localities in the northern Scotland, in 8 — 10 and 50 — 55 fm. (Th. Scott). 



This species is thus boreal and arctic and lives in \er\- nu)derate depths. Irom some few 

 fathoms and down to nearly 200 fathoms.

Female. The body of the females with marsnpium (fig. 4a) somewhat more than three times 

 as long as broad; in the immature female it is conspicuously more slender. — Carapace, seen from 

 above, with the lateral margins considerably convex excepting near the front end and two and a half 

 times as broad as this front end; the anterior margin feebly concave behind the anlcnnuki:, feebly 

 produced at the middle and at the lateral angles. — Eyes wanting.
