rapidly to the subacute apex, which bears two bunches of long setae, 

 4 in each, margins entire with fine scattered setules. 



First antenna not quite as long as head, 1st joint stout, twice 

 as long as broad, outer margin with long setae, 2nd shorter than 3rd, 

 outer apex of 3rd with 2 long setae, flagellum f length of 1st ped- 

 uncular joint, 7-jointed, 1st joint very wide and short, appearing 

 like a -4th joint of the peduncle, 2nd longest, rest decreasing gradu- 

 ally, apex setose. 



Second antenna as long as head, 1st joint short, 2nd swollen and 

 hollow on one side, 3rd and 4th subequal, ^ length of 2nd, 5th a 

 little longer, flagellum equal to 5th peduncular joint, 6-jointed, but 

 only the 1st is really distinct, the rest minute and setose. 



Upper lip triangular, cleft symmetrical, apices with small stout 

 spines. 



Lower lip, lobes broad, apically truncate, inner angles with 2 

 recurved spines and a few setules, rounded outer angles with a tuft 

 of setae. 



Mandibles, cutting-edge tridentate, cutting-plate with ca. 12 

 blunt teeth, molar prominent, palp rather slender, 1st joint | length 

 of 2nd, 3rd only J length of 1st and very slender, with 3-4 apical 

 spines. 



First maxilla rather stout, apically bent, 1 strong and 5 smaller 

 apical teeth. 



Second maxilla very small, stout, triangular, with 2 apical setae. 



Maxilliped, 1st joint distinct, 2nd short and broad, inner plate well 

 developed, half the length of 2nd, apically rounded, with a few 

 marginal setae, 3rd joint short, 4th nearly as long as 2nd, distal 

 margin oblique, 5th small with 1 spine and 3 apical setae ; there is 

 very minute 6th joint with 3 apical setae, but it is doubtful if it 

 is really separate from the 5th joint. Epipod subcircular, nearly 

 reaching apex of 2nd joint. 



First peraeopod stout, 2nd and 3rd joints subequal, 4th short, 

 outer margin angular, 5th twice length of 4th, completely under- 

 riding 6th, inner apex produced into a blunt lobe, inner margin 

 of 5th with small square pellucid plates set closely together, but 

 interrupted in places by long setae, on the apical lobe these plates 

 are finely fimbriate at the edges, 6th joint elongate oval, tapering 

 rapidly distally, palm straight, setose, 7th joint shorter than palm, 

 bearing a stout unguis as long as itself and reaching to the apical 

 lobe of 5th joint. 



Second and third peraeopods, 2nd and 3rd joints subequal, 4th 

 half as long, distally produced on outer margin, 5th underriding 6th,
