CRUSTACEA MALACOSTRACA. II. IOO , 



10 and 90 fathoms; in the cold area it was taken by the "Ingolf" at two stations, 293 and 537 fan.; in 

 the warm area by the "Ingolf at seven stations at depths varying from 318 to 1435 fathoms.

Female (without marsupium). G. O. Sars has published a very detailed description with 

 several figures of this sex, but a number of observations may be added. 



Body, carapace, thoracic segments and abdomen, seen from above, as to all particulars nearly 

 as in C. arctophylax Norm. & Stebb. (comp. description and fig. 2 a on PI. XI of this species). 



Antennulae (fig. 6 a) somewhat shorter than the carapace, moderately slender. First joint con- 

 siderably shorter than the three other joints combined, about two and half times as long as deep and 

 feebly tapering; second joint distinctly less than half as long as the first and considerably produced 

 above; third joint somewhat shorter than the second, almost quadrangular; fourth joint long, nearly as 

 long as third and second joints combined. Antennae somewhat long; fourth and fifth joints com- 



pletely fused. 



Chelipeds robust (fig. 6 a). A coxal joint is well marked off, large, somewhat triangular and 

 well chitinised on the outer side. Basal joint posteriorly produced into a moderately long, free, moder- 

 ately thick protuberance directed backwards and upwards, and the hind margin of this protuberance 

 is situated beneath the front margin of second thoracic segment. Carpus only somewhat longer than 

 deep, being somewhat expanded downwards and showing a somewhat protruding triangle below at 

 the front lower angle of the ischium. Chela almost half as long again as the carpus, robust, only a 

 little more than twice as long as broad; movable finger somewhat shorter than the anterior margin 

 of the hand, robust, with a conspicuous, subtriangular and moderately low tubercle at the middle of 

 the incisive margin (fig. 6b); fixed finger somewhat thicker than the movable, with three setae on its 

 posterior margin, while its incisive margin has a large, broad and somewhat high, rounded tubercle 

 beyond the middle and before the middle a low and badly defined protuberance; both fingers with 

 their end obtuse. 



Thoracic legs rather long and slender, with their spines short or moderately short Anterior 

 pairs (fig. 6c) with the joints increasing much in length from the fourth to the sixth; sixth joint very 

 long and slightly longer than seventh with claw. Posterior pairs as in the next species (vid. infra). 



Abdomen (fig. 6d) somewhat shorter than the three preceding segments combined. Five anterior 

 segments with their ventral surface peculiarly armed; first segment with the ventral process somewhat 

 short, obliquely and obtusely triangular; process of second segment long, longer than broad, obliquely 

 triangular, somewhat curved and directed much backwards; the processes decrease much in length 

 from second to fourth segment, while the process on fifth segment is only a moderately low, rounded 

 tubercle. Pleopods very small, biramons, without setae. (In juvenile specimens with the seventh pair
