spines and several shorter ones, 3rd joint falciform, with short 

 marginal spines and longer serrate apical ones. 



First maxilla, inner lobe with 3 strong spines, 1 weaker one 

 between the bases of the two inner spines, a small tooth and some 

 fine setules, outer lobe witli 11 more or less serrate spines. 



Second maxilla, outer and middle lobes with 4 spines, inner 

 plate broader, with several serrate spines on inner margin. 



Maxillipeds, epipod reaches to apex of 4th joint, apex of inner 

 plate with blunt teeth and serrate spines, three very short and 

 broad coupling-hooks. 



First paraeopod (gnathopod) male, 3rd joint strongly and acutely 

 produced on upper margin, 4th joint subacutely produced, 5th 

 joint not produced on lower margin, 6th joint as broad as long, 

 thick and convex above, with a thin laminar process below forming 

 the palm and hind margin, front margin convex, setose, hind margin 

 densely setose, about as long as the palm, which is transverse, 

 setose, and has 2 strong teeth in the centre and a third tooth at its 

 junction with the hind margin, finger curved, longer than palm, 

 finely setulose. 



First peraeopod (gnathopod) female, much smaller than in $ , 

 3rd joint strongly and acutely produced on front margin, 4th joint 

 likewise produced in front and also less strongly on hind margin, 

 5th joint larger proportionately and squarer than in $ , 6th joint 

 half as long again as broad, margins nearly parallel, front margin 

 with a few isolated setae, hinder densely setose, palm shorter than 

 hind margin, transverse, defined by a strong spine and bearing a row 

 of pectinate spines decreasing in length towards the hinge of the 

 finger, where there is a bunch of longer setae, finger stout, only a 

 little longer than palm, with spiuulose inner margin. 



Second peraeopod (gnathopod) slender, 2nd joint as long as or a 

 little longer than 3rd and 4th combined, 3rd joint a little longer 

 than 4th, with 1 spine in centre of front margin, 4th joint produced 

 in front, with 1 apical spine, 6th joint a little shorter than 2nd, 5th 

 joint a little shorter than 6th, 7th joint one-third length of 6th, 

 biunguiculate. 



Third-seventh peraeopods do not differ from the second peraeo- 

 pods. 



First pleopod, male, peduncle with 2 submediau spines, each 

 ramus with a long seta in the centre and a row of marginal setae. 

 First pleopod, female, tapering distally with bifid apex. 

 Second pleopod, male, as figured by Hansen but apex of penial 

 filament is acutely pointed.
