 nearly half length of 1st but narrower, 3rd joint f length of 1st, 

 slender, flagellum nearly as long as peduncle, 8-jointed. 



Second antenna reaching to posterior margin of 1st peraeon

Epistome prominent in a dorsal view of the animal, proximal 

 end straight, angles rounded, margins strongly concave, the arms 

 wide and embracing the upper lip.

 left), secondary cutting-edge in the left feebly bifid, spine-row 

 with ca. 8 spines in the left and ca. -4 in the right, molar oblique, 

 setiferous ; palp with 1st and 2nd joints subequal, 3rd shorter. 



First maxilla with 8 spines on outer lobe, the 4 inmost spines 

 serrulate. 



Second maxilla with ca. 8 setae on outer and middle lobes. 



Remaining mouth parts as in normal Exospliaeroma. 



First peraeopod, outer margin of 3rd joint and apex of 4th each 

 with 1 spine, inner margin of 6th joint with 2 spines near apex. 



Second peraeopod, outer apex of 4th joint with 2 spines, 5th joint 

 without spines. 



Third to seventh peraeopods, 5th joint with serrate spines all 

 round apex, inner margin of 6th joint of 7th peraeopod not furry, 

 with 2 distant spines. 



Male appendages on 7th peraeon segment short, blunt, and some 

 distance apart. 



Second pleopod, inner apex of peduncle with 3 hooked spines, 

 male stylet half as long again as ramus. 



Third pleopod, outer ramus distinctly 2-jointed. 



Fourth and fifth pleopods, outer ramus membranous and 

 2-jointed. 



Uropods not extending more than | length of telson, inner 

 ramus parallel-sided, apex feebly bifid, outer ramus rather longer 

 than inner, ovate-lanceolate, apex acute and outwardly recurved. 



Length ': 5 mm. ; breadth : 2 - 5 mm. 



Colour : Light brown with the lateral parts of the 4th peraeon 

 segment, the base of the pleon and a band across the telson and
