jecfciou not extending beyond the antero-lateral angles, eyes oval, 

 black. Peraeon with 1st segment longer than the others, segments 

 2-5 subequal and a little longer than head, segments 6 and 7 sub- 

 equal and rather shorter than preceding segments, anterior margin 

 of segments 3-5 (in the large specimen segments 4 and 5) with a 

 small pit. Pleon segments 1-5 completely fused, without trace 

 of sutures, equal in length to 7th peraeon segment. Telson with 

 straight sides, tapering gradually to the bluntly rounded apex, 

 margins setose, the apical setae being the longest. 



First antenna as long as head, 1st joint stout, 2nd and 3rd 

 slender, 3rd a little shorter than 2nd, flagellum as long as 3rd 

 joint, 3-jointed, the 2nd joint by far the longest, 3rd apically 

 setose. 



Second antenna rather longer than head, 2nd joint stout and 

 twisted, 3rd and 5th subequal, 4th shorter, flagellum apparently 

 only 1-jointed, setose. 



Upper lip triangular, the incision nearly in the median line. 



Lower lip, lobes apically truncate, inner apical angle well marked, 

 not setose. 



Mandibles, cutting-plate with many fine backwardly directed 

 denticulations, molar fairly prominent, palp strong, 1st joint short, 

 2nd and 3rd subequal and twice length of 1st, inner margins 

 setulose, apex of 3rd with stronger setae. 



First maxilla, apex with one strong spine and 5 smaller 

 ones. 



Second maxilla small, triangular, the subacute apex with 

 1 seta. 



Maxilliped, 1st joint distinguishable in the large specimen but 

 not in the smaller, 2nd joint longest, 3rd a little shorter, both 

 margins setose, the inner setae being the stronger, 4th joint small, 

 with 2 strong inwardly directed setae on apex, epipod small, 

 rounded. 



First peraeopod, 5th joint narrow, apex pointed and curving 

 slightly outwards, with subapical setae, Gth joint narrow-oval, 

 tapering distally, inner margin (palm) with 1 outwardly curving 

 tubercular spine and setae in front of and behind this, 7th joint 

 slender, reaching to apex of 5th joint. 



Second and third peraeopods, 5th joint small, underriding Gth, 

 without any external margin, Gth joint with 1 doubly denticulate 

 spine on inner apex, 7th joint with inner margin denticulate. 



Fourth to seventh peraeopods similar to 2nd and 3rd, but 5th 

 joint has a short external margin, peraeopod 7 is longer than rest
