Mandibles stout, apex bifid in the left mandible, in the right 

 entire, with 2 minute spines on inner side a little below apex, 

 molar prominent, denticulate. 



First maxilla, masticatory lobe curved, outer margin serrulate, 

 apex with ca. 9 non-serrate spines and a bunch of setae external 

 to them, backward-bent "palp" ending in several setae (3-8). 



Second maxilla tooth-like, apparently only 1-jointed, with broad 

 basal portion, distal half suddenly narrowed, pointed. 



Maxillipeds, 1st joint short with 3 long spines on inner margin, 2nd 

 joint stout, 1^ times as long as broad, outer margin distally serrulate, 

 3rd and 4th joints subequal, outer margin of 3rd joint serrulate, 

 5th joint a little longer, 6th joint narrow, with apical setae, inner 

 plate reaching to middle of 4th joint, apex rounded, setose, inner 

 apical angle with 1-2 long curved setae (coupling-hooks), epipod 

 apparently absent (6 specimens were examined and no trace of it 

 could be found). 



First gnathopod $ , thumb of propodos with incisive edge 

 extending from apical tooth to hinge, where it ends in a prominent 

 tubercle, at distal end a row of setae along its base, finger strongly 

 curved, very slightly thickened before the apical tooth, which fits 

 within that on the thumb. 



First gnathopod $ , not quite so stout as in $ , thumb of propodos 

 with the incisive edge extending from apical tooth half-way along 

 thumb, a small setiferous tubercle near hinge, finger not much 

 curved, slightly bulbous at base internally, with apical tooth fitting 

 within that on the thumb. 



Second gnathopod $ , ambulatory, 2nd joint longest, 3rd joint 

 shortest, 4th joint shorter than 5th, which is a little over half length 

 of 2nd, 6th slender bearing a slender spiniform unguis as long as 

 itself. 



Second gnathopod $ , similar but not so elongate. 



First and second peraeopods, stouter and longer than second 

 gnathopod, 2nd joint cylindrical, 3 times as long as broad, 3rd joint 

 half length of 2nd, 4th joint a little shorter, with ca. 6 strong apical 

 spines, 5th joint equal to 3rd, 6th joint with its slender nearly 

 straight unguis half length of 5th, posterior margins of 3rd, 4th, and 

 5th joints serrulate. 



Third-fifth peraeopods stouter than 1st and 2nd peraeopods, 

 2nd joint fusiform, twice as long as broad, 3rd and 4th joints 

 subequal, shorter than 5th, 3rd joint with 1 apical spine on inner 

 margin, 4th joint with ca. 6 strong apical spines, 6th joint rather 

 more than half length of 2nd, with a strong falciform unguis.
