all segments except 1st, granular, especially the posterior ones, each 

 with a slight hollow ahove the oblique carina ; a carina is also 

 present on lateral margin of 1st segment ; epimera of 2nd and 3rd 

 segments posteriorly rounded, of segments 4-7 becoming gradually 

 more produced and acute, but never sharply pointed, epimeron 

 of segment 6 reaching postero-lateral angle of 1st pleon seg- 

 ment, of segment 7 reaching middle of lateral margin of 2nd pleon 

 segment. 



First segment of pleon very short, but not completely concealed 

 dorsally by the 7th peraeon segment, other segments subequal, 

 posterior margins granular, postero-lateral angles of 1st 1th seg- 

 ments subacute ; telson subtriangular, apex rounded with median 

 projecting point, surface granular, excavate at base on either side of 

 the median carina which extends to apex, margin fringed with 

 plumose setae and crenulate, with a stout spine springing from 

 each indentation (ca. 12 on each side). 



First antenna extending to middle of eye and nearly to end 

 of 5th peduncular joint of 2nd antenna, 1st and 2nd joints strongly 

 expanded, 2nd joint shorter than 1st, exterior apex produced, 3rd 

 joint slender, not extending far beyond external apex of 2nd, 

 flagellum a little longer than 1st peduncular joint, 8-jointed. 



Second antenna reaching to posterior margin of 2nd peraeon 

 segment, peduncular joints increasing in length, 5th joint equal 

 to 1st joint of 1st antenna, flagellum half as long again as peduncle, 

 22-jointed. 



Mandible with apex incurved at right angles to trunk, tapering, 

 acute, palp longer than trunk, 2nd joint twice as long as 1st and 

 thrice as long as 3rd, outer margin of 3rd and apices of 2nd and 

 3rd joints setose. 



First maxilla slender, apex with 5 apical hooked spines and one 

 smaller subapical. 



Second maxilla with trunk broad at base, rapidly narrowing, 

 outer lobe broader than apex of trunk, with 3 strong curved 

 spines, inner lobe half length and width of outer, with 4 curved 

 spines. 



Maxilliped, 1st joint very short, 2nd joint 2^ times as long as 

 broad, 3rd joint short, 4th joint triangular, produced internally, 5th 

 joint also triangular, inner apex produced with 4 spines, 6th joint 

 twice as broad as long, inner margin with 5 strong hooked spines 

 and 2 smaller ones, 7th joint wide but very short, with 4-5 setae ; 

 inner plate extending half-way along 4th joint, narrow, apex with 

 2 setae.
