The epistome projects anteriorly as an ovate plate 

 strengthened above by a keel, whose base is in close contact 

 with a short truncate rostral projection, bearing a small 

 swelling on each side. 



The head is short, extended laterally to obtuse points ; 

 the eyes are prominent and large. 



The first thoracic segment is medianly short with its 

 epimeral regions reaching a little anterior to the eyes. The 

 rest of the segments are short and differ little from one 

 another. 



The anterior portion of the abdomen shows two segments 

 with an anterior one almost completely covered by the las£ 

 segment of thorax. The posterior portion is domeshaped, the 

 end being rounded without notch or channel. 



The basal antennular joint is trilobed, the anterior lobe 

 is laminate, a little curved outwards, and reaches much 

 beyond the epistomial projection, it has a superior thick- 

 ening; the median lobe is not laminate, but shorter and 

 narrow, also thickened above, and has near its end on the 

 inner side an opaque swelling like a gland ; the lobe is 

 apparently hollow ; the posterior lobe is small and laminate. 

 The second joint is slightly expanded, with its antero-distal 

 angle a little produced, the third joint is narrow, the 

 flagellum short with 5 or 6 joints. 



The antennal peduncle is of ordinary kind ; its flagellum 

 carries 12 joints, which reach as far as the fourth thoracic 

 segment. 



The mandibles are small and short with incisory plate, 

 secondary plate, spine row, and molar not much projecting; 

 the palp is long and slender. 



The first and second pairs of 'maxillae are short and of 

 the usual type. 



In the maxillipeds the plate of the second joint is rather 

 short with a distal crowd of short setse. The palp is large ; 

 the third joint is as long as the second, its lobe is proximal, 

 so that a wide gap exists between it and that of the penulti- 

 mate joint; this joint is short with a long lobe, which is 

 longer and larger than the terminal joint and is situated close 

 to it, so that the setae of both intermingle. 



The first gnathopod is a peculiar prehensile apparatus. 

 The basis, which is nearly as long as the succeeding joints 

 taken together, is slender and a little curved outwards, the 

 merus has its "heel" prolonged, reaching as far as the end 

 of the propodus, where it carries about 10 long, curved, stiff 

 setae; the propodus also reaches beyond the insertion of the 

 dactylus, this part being thickened and carrying about 6 

 similar setae; the dactylus is long and slender.
