margin into a long and broad rostrum, with 4-5 teeth on lateral 

 margins and a bluntly rounded apex, eyes well developed on the 

 lateral projections. 



Peraeon with 1st segment very large, swollen and gibbous, as long 

 as the 3 following segments together, segments 2-4 equal in length, 

 lateral margins subquadrate, with 1 spine on antero-lateral angle, 

 segments 5-7 equal and a little longer than the anterior segments, 

 diminishing gradually in width, lateral margins rounded, with 1 spine 

 on antero-lateral angles. Epimera visible only on segments 5-7, 

 with 1 spine. 



Pleon of one piece, oval, margins entire. 



First antenna, peduncle stout, 2nd joint half length of 1st, 

 flagellum 3-jointed. 



Second antenna, first 3 peduncular joints stout, short, 4th and 5th 

 elongate, subequal, flagellum nearly as long as peduncle, 15-jointed. 



Upper lip with rounded, setose distal margin. 



Lower lip, lobes rather short, ovate, outer margin distally setose, 

 inner margin distally emarginate, apex subacute. 



Mandibles narrow, cutting-edge tridentate, secondary cutting-edge 

 on left tridentate, absent on right, spine-row with 5 spines in both 

 mandibles, molar prominent, no trace of a palp. 



First maxilla outer plate with 7 spines, some denticulate on outer 

 margin, inner plate with 4 setae. 



Second maxilla, outer and middle plates each with 4 spines. 



Maxilliped, 2nd joint increasing in width distally and passing into 

 inner plate without distinct suture, outer margin of inner plate 

 oblique, setose near apex, 2 coupling-hooks at base, 3rd joint short, 

 4th and 5th joints subequal, 6th a little longer and 7th a little 

 shorter, epipod reaching to about middle of 4th joint. 



First peraeopod, 2nd joint longest, 3rd with 3 spines on outer 

 apex, 4th strongly produced externally, with 2 spines on subacute 

 apex, 5th triangular, outer margin spinose, distal margin with 

 7 stout blunt spines, each with a cilium near apex, 6th oval, 

 palm with 3 spines, 7th slender as long as 6th, with a single 

 slender unguis. 



Second to seventh peraeopods similar to one another except that 

 2nd is a little stouter and has 5th joint elongate-oval instead of 

 oblong ; 6th joint longest, 7th short, with 2 ungues. 



First pleopod $ , peduncle tapering, apices curved outwards, 

 acute, a group of fine setae half-way along outer margin, ramus 

 obscurely separated from peduncle, with 2 spines. 



Second pleopod J , peduncle elongate-lanceolate, apex acute, outer
