Forekomst. Et enkelt Exemplar, en fuldt udviklet 

 Han. af denne Art toges umler Expeditionens 2det Togt 

 i Havet NV. af Finmarken (Stat. 195) paa et Dyb af 107 

 Favne. Stationen tilhører den tempererede Area, og Arten 

 kan derfor, trods Findestedets nordlige Beliggenhed, heller 

 ikke med Sikkerhed erklæres for en arktisk Form.

Artscharacteristik. - - Legemet noget forlænget, med 

 de forreste Epimerer omtrent at' Kroppens Hoide. Hove- 

 det* Sidehjorner tilspidsede. ISdie Bagkropssegments Side- 

 plader bagtil stumpt tilrundede. Øinene smaa, ovale, med 

 mørkt Pigment. Følerne kraftigt udviklede. over halvt saa 

 lange som Legemet, og bagtil forsynede med lange, kam- 

 formigt ordnede Børster; Iste Par med Skaftets Iste Led 

 af Hovedets Længde, de 2 følgende indbyrdes lige lange, 

 Bisvoben meget liden. neppe mere end '/. ; saa lang som 

 Svobens Iste Led, samt 1-leddet; 2det Par med Svohen 

 noget længere end Skaftets sidste Led, 8-leddet. 2det Pod- 

 par hos Hannen meget stort, med stærkt opsvijlmet, aflang 

 oval Haand uden tydeligt begrændset Griberand, men bagtil 

 tæt besat med tildels cilierede Børster. De øvrige Fødder

Findesteder. Stat. 137. 280. 



Bemærkninger. Denne Art staar nærmest P. ntega- 

 cheir Boeck, men skiller sig ved en noget robustere Krops- 

 form, større Epimerer, den rudimentære Beskaffenhed af 

 Iste Par Føleres Bisvøbe, samt derved, at 3die Bagkrops- 

 segments Sideplader ikke er vinklede, men stumpt afrun- 

 dede bagtil. 



Beskrivelse. Legemet er ise Pl. XVII. Fig. 1) noget 

 langstrakt, skjøndt idethele adskilligt robustere end hos dens 



nærmeste Forvante P. megacheir Boeck. 



Oeeurrence. — Only one example of this species, a 

 fully developed male, was tåken on the Expedition (2nd 

 cruise), north-west of Finmark (Stat. L95), a1 a depth of 

 107 fathoms. The Station was located in the temperate 

 area; aud the species cannot therefore, notwithstanding the 

 northern Locality in which it occurred, with certainty be 

 reearded as an Arctic form.

Remarks. — This species approximates closesl P. me- 

 gacheir Boeck, 1 mt dillers trom that animal in having a 

 somewhat robuster tonn ol' body. larger epimera, the riuli- 

 mentary character distinguishing the secondary flagellum of 

 its Ist pair of antenna', as also in the lateral plates of 

 the 3rd abdominal segment not being angular, but obtusely 

 rounded posteriorly. 



Deseription. — The body (see Pl. X V 11, fig. 1 i is some- 

 what elongate, though on the whole a trifle more robust 

 than in its nearest related congener, /'. megacheir Boeck.
