Second maxilla, outer and middle plates with 3 long spines, inner 

 plate nearly twice as wide, with numerous setae. 



Maxillipeds, 2nd joint stout, width equals outer margin, 3rd joint 

 twice as broad as long, 4th joint and proximal half of 5th broad, 

 5th joint narrowing rapidly distally, 6th joint not very slender, 

 7th joint shorter than 6th, inner plate with rounded-truncate 

 spinose apex, inner margin with 2-3 short stout coupling-hooks, 

 epipod reaching to the 4th joint, oblong, outer distal margin 

 obliquely truncate, not setose. 



First peraeopod (gnathopod) $ , 3rd joint two-thirds length of 2nd, 

 4th joint half length of 3rd and shortly produced in front, 5th joint 

 equal to 2nd, hind margin slightly expanded, with one long stout 

 apical spine and one shorter subapical one, 6th joint slender, equal 

 to the 5th, setose on both margins, 7th joint very short, biunguiculate 

 with small tooth at base of ungues. 



Second and following peraeopods similar to first but stouter and 

 rather shorter, expansion on 5th joint not so marked, apical and 

 subapical spines small, inner margin of 6th joint with solitary 

 spines, outer margin setose, triunguiculate. 



First pleopods $ , peduncles fused basally, diverging distally, with 

 well-developed rami. 



Second pleopod $ , peduncle longer than broad, narrowing distally, 

 exopod arising at apex of peduncle, distal portion of penial filament 

 a little longer than peduncle. 



Third pleopod, outer ramus stout, longer than and nearly as broad 

 as inner, 2-jointed, inner ramus with 3 apical plumose setae. 



Fourth pleopod, widest portion of outer ramus only half the width 

 of inner, 2nd joint tapering, with apical setae. 



Uropods, both rami longer than peduncle, outer shorter than 

 inner, both margins undulate and with groups of spines, apices 

 also with spines. 



Length : 4 mm. ; breadth : 2 mm. Second antennae : 6 mm. 



Colour: Whitish, with minute stellate specks of dark pigment.
