 spine on lower apex, 2nd joint with 4 spinules on upper margin 

 and 2 spinules on upper apex, 3rd joint 1 length of 2nd, flagellum 

 equal to 2nd and 3rd peduncular joints together, 14-jointed.

 5 in right, molar denticulate and setose, palp very stout, especially 2nd 

 joint, which is scarcely curved but strongly angular on inner basal 

 margin, 3rd joint not as long as 2nd, more slender than either 1st or 

 2nd joints. 



First maxilla, inner plate with 3 apical setae and some very fine 

 setules on inner margin, outer plate with 9 spines, some of them 

 tending to be bifid, palp with 2nd joint widest in middle, inner distal 

 margin with ca. 8 setae, 4 apical setae, outer distal margin with 

 2 groups of 3 setae each. 



Second maxilla, inner plate broader than outer, both setose. 



Maxilliped, inner plate extending just beyond apex of 2nd joint 

 (not of palp) , inner apical angle with 1 spine, apical margin setose, 

 outer plate not quite reaching end of 2nd joint of palp, inner margin 

 with setae and strong spines, 2nd joint of palp not strongly expanded 

 distally, 4th joint as long as 3rd. 



First gnathopod, 5th joint produced into a lobe bearing several 

 setae and 2 apical spines, 6th joint ovate, almost as long and as broad 

 as 5th, palm convex, not very oblique, subequal to inferior margin, 

 palmar spine present in one specimen only, finger just overlapping palm. 



Second gnathopod, 5th joint produced into a lobe but not so strongly 

 as in 1st gnathopod, with numerous setae and 2 long apical spines, 6th 

 joint shorter but a little broader than 5th, similar to that of 1st 

 gnathopod. 



First and second peraeopods, 4th and especially 5th joints rather 

 strongly setose and spinose, 4th longer than 5th or 6th, which are

 longer than, 6th, not strongly tapering, ending in a minute curved 

 unguis.
