slightly emarginate, antero-lateral angles not prominent, eyes in 

 middle of lateral margin, dark. Peraeon with both anterior and 

 posterior margins of 1st segment concave, 1st segment in middle 

 line ? f length of 2nd, 2nd -4th subequal, 5th-7th subequal and as 

 long as 1st. Epimera of 2nd-5th segments f as long as their 

 segments, not quite reaching posterior margin, those of 6th and 7th 

 segments as long as their segments. Pleon equal in length to last 

 4 peraeon segments together, with 1 complete and 2 incomplete 

 lateral sutures, slightly tapering to a rounded apex with a small 

 shallow semicircular notch. 



First antenna reaching to middle of 3rd peduncular joint of 2nd 

 antenna, basal joint stout, enlarged, nearly 3 times as broad as 

 2nd joint, 2nd and 3rd subequal, flagellum as long as 1st joint, with 

 ca. 13 groups of sensory filaments in pairs and a few setules. 



Second antenna reaching to, or a little beyond, end of 2nd peraeon 

 segment, 1st joint smaller than 2nd, excised on outer apical margin, 

 2nd-4th joints subequal, 5th a little longer, flagellum a little longer 

 than peduncle, 18-21-jointed. 



Upper lip broader than long, distal margin straight or slightly 

 emarginate, setiferous. 



Lower lip, lobes stout, inner margin oblique, with strong stout 

 setae. 



Mandibles, both geniculate, cutting-edge 4-dentate, secondary 

 cutting-edge tridentate in left, bidentate and weaker in right, spine- 

 row with ca. 4 spines, molar denticulate with setules on posterior 



margin. 



First maxilla, outer plate with 7 spines, inner plate with 3 plumose 

 setae. 



Second maxilla, outer and middle plates with G spines. 



Maxilliped narrow, 7-jointed, 3rd joint very short, 5th produced 

 at inner apex, 6th nearly as long as 2nd, 7th semicircular, short, 

 inner plate as long as 2nd joint, with 1 coupling-hook, epipod 

 reaching to end of 4th joint, narrow, lanceolate, apex blunt, slightly 

 incurved. 



Peraeopods not very slender; 1st peraeopod shorter than rest, 

 6th joint oblong, not ovate, nor enlarged, inner margin with 3 large 

 serrate spines and numerous pectinate setae. 



Second peraeopod, 6th joint with 2 large serrate spines but no 

 pectinate setae. Third peraeopod similar to 2nd, but only 1 spine on 

 6th joint. 



Fourth to seventh peraeopods with thick fur on inner margin of 

 4th-6th joints.
