Peraeon segments 1 and 4-6 longest, subequal, 2, 3, and 7 also 

 subequal, all segments ventrally keeled. 



Pleon segments 1-5 equal to 7th peraeon segment, fused, the sutures 

 distinct, telson ovate, nearly twice as long as broad, tapering to an 

 acute apex with ca. 4 apical setae. 



First antenna, 1st joint slender, not swollen, 2nd ^ length of 1st, 

 3rd | length of 1st, flagellum equal to 3rd peduncular joint, 1st joint 

 very small, 2nd longest, 3rd minute, setose. 



Second antenna, 5th joint slightly longer than 3rd and 4th, which 

 are subequal, flagellum equal to 4th joint, obscurely 3-jointed, apex 

 setose. 



Upper lip symmetrically cleft, apices spinulose. 



Lower lip, lobes not very broad, outer margin setose, apices with 

 a small point. 



Mandibles, cutting-edge indistinctly bidentate, cutting-plate 5- 

 dentate, molar fairly prominent, palp with 2nd joint longer than 1st, 

 3rd shorter than 1st, apex with 3-4 setae. 



First maxilla normal. Second maxilla minute with 1 apical 

 seta. 



Maxilliped, 1st joint indistinguishable, 3rd short, 4th a little 

 shorter than 2nd, 5th small with 3-4 apical setae, no inner plate 

 visible, epipod small, oval. 



First peraeopod, 5th joint apically produced, setose on inner 

 margin, 6th ovate, palm with distal half abruptly excavate, setose, 

 7th joint short and stout, reaching half-way along palm, unguis 

 short and very stout. 



Second and third peraeopods, 2nd joint longest, 5th completely 

 underriding 6th, its apex truncate, setose, 6th stout, inner margin 

 setose and beset with regular denticulations, which under a high 

 power are seen to be fimbriate, 1 apical serrulate and cihate 

 spine. 



Fourth to sixth peraeopods similar, but 5th joint not completely 

 underriding 6th, with an apical spine. 



Seventh peraeopods, both incomplete in the single specimen. 



First pleopod with 6 hooked spines on inner apex of peduncle. 



Uropods, inner ramus a little longer than telson, narrow, 2nd 

 joint shorter than 1st, half as long again as broad, apex subacute, 

 outer margin setulose ; outer ramus a little longer than 1st joint of 

 inner ramus, obliquely ovate, inner margin setose, distally emar- 

 ginate. 



Length: 17 mm. ; breadth: 1-5 mm, 



Colour : In spirit, dirty pink.
