HO CRUSTACEA MALACOSTRACA. II. 



of thoracic legs not developed the pleopods and the ventral processes are not found). Sixth segment 

 about as long as fifth, fourth and half of the third segment combined. Uropods (fig. 6d) small and 

 robust; both rami distinctly two-jointed (also in juvenile specimens) and the exopod somewhat shorter 

 and much thinner than the endopod. 



Length of the single larger specimen 4 mm .; Sars stated that the female is 5.5""". long. 



Remarks. The differences between the females of C.Voringii and C.arctophylax are pointed 

 out in the "Remarks" on the latter species. Sars stated that the uropods of the female have the exopod 

 one-jointed, but this is decidedly incorrect; his figure of the chela is not good, and he has described 

 and figured (figs. 5 and 6) the terminal part of the thoracic legs, viz. seventh joint with claw, quite 

 erroneously. 



Occurrence. Taken by the "Ingolf" at three stations in the cold area. 



North- West of the Faeroes : 81.138: Lat. 63 26' N., Long. 7 56' W., 471 fm., temp, -f- 0.6; i large spec. 



South of Jan Mayen: Stii7: Lat6o.i3'N., Long.823' W., 1003 fm., temp. -=- 1.0; ijuven.spec. 



Stn6: Lat.7o05'N., Long. 8 26' W., 371 fm., temp. -4- 0.4; ijuven.spec. 



Distribution: The specimens seen by Sars had been taken at three places in the cold area 

 West of Norway, from Lat 63 10' to Lat. 67 56' N., and in depths ranging from 350 to 778 fathoms; 

 temperatures at the bottom from -4- 1.0 to -=- 1.4.

Young Female and subadult Male. Body of the subadult male (fig. 2a) robust, slightly 

 more than five times as long as broad and the anterior half conspicuously broader than the posterior; 

 the young female is about five and a half times as long as broad. Carapace nearly as long as the 

 two following segments combined, as long as or slightly longer than broad, anteriorly somewhat less 

 than half as broad as behind the middle, where the lateral margins are very convex. 



Antennulae in the subadult male (fig. 2 a) a little, in the young female somewhat, shorter than 

 the carapace. In the female (fig. 2 e) the antennulse are somewhat slender; first joint considerably 

 shorter than the three following joints combined, somewhat less than three times as long as deep and 

 feebly tapering; second joint somewhat produced above, not fully half as long as the first, but much 

 longer than the third which is a little shorter above than below ; fourth joint almost as long as third 

 and second joints combined and a little longer than the terminal setae. In the subadult male the 

 antennulse (fig. 2b) are much thicker; first joint slightly more than half as long again as deep; second 

 joint as deep as the length of its upper margin, which is half as long as the first joint; third joint 

 more than half as deep again as the length of its upper margin; fourth joint uncommonly long, 

 conspicuously longer than the two preceding joints combined, with the proximal portion somewhat 

 thickened, and the terminal setse are considerably shorter than the joint. Antennae somewhat long, in 

 the young female (fig. 2e) with, in the subadult male without, a vestige of an articulation between 

 fourth and fifth joints.
