setiferous lobes close together on the median line, the oblique ridges 

 with a low rounded tubercle just above the posterior margin of eye 

 and another larger and f orwardly directed further back ; behind these 

 tubercles the surface of the head shows a number of points, which do 

 not appear to be granules but are very distinct. Eyes not very 

 prominent. 



Peraeon segments 2 and 3 subequal in length, equal to head in 

 width ; segment 4 slightly narrower, not separated by a constriction 

 from segment 3 ; segment 5 completely separated into two lateral 

 portions by the meeting of segments 4 and 6 in the middle line ; none 

 of the segments swollen laterally. 



Pleon not as long as peraeon, telson with slightly convex sides, 

 apex acute, with 2 setae. 



Female. Nearly twice as long as broad. Head with a very slight 

 notch on anterior margin. Peraeon segments ruptured, relative 

 lengths of the segments consequently impossible to determine. 



Antenna 1 g , 3rd joint slightly the longest, flagellum 4 jointed, 

 2nd joint much the largest. 



Antenna 2 $ , 4th and 5th joints subequal. Flagellum 4-jointed. 



Mandible , greatest breadth less than length, apex not slender, 

 subacute, inner margin gently convex, quite smooth ; tooth on outer 

 margin very prominent, its front margin slightly denticulate. 



Maxilliped, 2nd joint produced on inner distal angle, 4th joint of 

 palp not incurved. 



Peraeopod 1 <$ , semicircular, not tapering, outer margin slightly 

 emarginate, inner margin setose, 2nd joint rather elongate oval, tipped 

 with setae ; in $ 2- jointed, with a nick in 1st joint. 



Peraeopods 2 and 3 $ , 3rd-5th joints strongly tuberculate on 

 lower margins, 6th joint with 1 apical spine and 1 in middle of lower 

 margin. 



Peraeopods 4-6 similar, but the tubercles not quite so large as in the 

 anterior peraeopods 



Peraeopods in $ more slender than in $ , with only a single apical 

 tubercle on the 4th and 5th joints 



Pleopods with 2 hooked setae on peduncle and narrow subequal rami. 



Uropod, outer ramus narrower and stouter than inner, both with 

 plumose setae. 



Length: $ 3'5mm., $ 3mm.; breadth: 1'5 mm., 9 175mm. 



Colour : In spirit yellowish, eyes dark, mandibles white. 



Locality : Knysna Heads NE. -} E., distant 3 miles. 40 fathoms.
