﻿CRUSTACKA MAI.ACOSTRACA. II. 53 



tliis species soinewliat uncertain, tliouyli, on the other hand, the anleiinuhc, tlie chel:e, tlie second 

 pair of legs and tlie shape of the last abdominal segment show close relationsliii) to the above-de- 

 scribed males of the two other species of this genns, and no other species of the gemis is known tf) 

 which the male might jiossilih' belong. P'or these reasons I ha\c described and figured this male 

 and referred it, with a qnery, to P. affinis.

 Besides the species has been secured by the II'' Amdrup Exped. at a single locality. 



East Greenland: Forsblad Fjord, at Lat. 72"^ 27' N., Long. 25° 28' W., 50 — 90 fm. ; i spec. 



Distriliution. The type specimens were taken in the Kara Sea, 64—65 fm. (H. J. Hansen). 

 — According to the list of localities the species has been taken four times in the warm area in depths 

 from 318 to near 1200 fm., and the highest temperature is 4.5°, but besides it is widely distributed in 

 the cold area in depths from 371 to loio fm. and the lowest temperature was -4- 1.0°; finally it has 

 been captured at cold localities in the northern East Greenland and the Kara Sea in much lesser 

 depths, viz. between 50 and 90 fm. 



19. Pseudotanais longipes n. sp. 



(PI. Ill, fig.s. 4a— 4 i.) 



Female. The body scarcely four times as long as broad. — Carapace strongly tapering in 

 breadth forwards (fig. 4b), with the lateral margins not much convex; the anterior margin, wliich is 

 even a little less than one-third as long as the breadth of the carapace somewhat before its liiud 

 margin, is feebly concave at each antennula. — Eyes wanting. 



Antennukc very elongate, twice as long as the carapace (fig. 4a) and extremeK- slender (tig. 4CI. 

 First joint more than six times as long as deej) though its ])roxinual part is .somewhat thickened be- 

 low, slightly longer than the two other joints cond)ined; second joint not half as long as the tlnrd; 

 the setae on all jcjints extremely long. — The auteumc (fig. 4c) are very slender; liiird joint shorter
