244 Annah of the South African Museum. 



The eyes as preserved are a light orange in colour ; the stalk carries 

 several setules. The first antennae have the three joints of the 

 peduncle nearly equal in length, but the first much the stoutest ; the 

 flagella are very short. In the second antennae the slender six- jointed 

 flagellum is slightly longer than the peduncle. 



The mandibles are rather short but strong, with the palp membraneous. 

 The first and second maxillae are rather feeble. In the first maxillipeds 

 the epipod is very broad at the base. The second maxillipeds appear 

 remarkable by exhibiting a character familiar in the first maxillipeds 

 of some other genera, such as Pinnotheres, Latreille, and Pinnixa, 

 White, namely the chela-like arrangement of the ultimate and penul- 

 timate joints of the eudopod. The rounded ends, however, of both 

 joints make any chelate function in the present case rather difficult to 

 explain. The place of insertion of the seventh joint is similar in 

 Hexapus but without cheliform prolongation of the sixth joint. The 

 epipod of these maxillipeds is narrow ; in both sexes it shows at the 

 base two small elevations of the outer margin. The third maxillipeds 

 have been already described as part of the generic character. 



The chelipeds are massive compared with the other limbs, and 

 show various rows of granules and setules on the fourth to the seventh 

 joints. The curved fingers close accurately together, the movable 

 finger equalling the palm in length. The second peraeopods are 

 shorter than the third, but similar in structure, both pairs having the 

 last two joints strongly setose ; the finger in the third pair is very 

 elongate. The fourth and fifth peraeopods are very much smaller, 

 with the last two joints a little curved as if for grasping. These limbs 

 were present only in one of the specimens, and only on the left side of 

 that, as shown in the figure. I have been unwilling to remove them 

 for more accurate delineation, and no representatives were present 

 among the detached limbs of other specimens. 



The male stilet is elongate, its needle-like apex reaching nearly the 

 end of the pleon. The four pairs of pleopods of the female show long 

 plumose setae on one branch and simple setae on the other. 



The carapace of the male specimen figured has a length of 9 mm., 

 with a rather smaller breadth.
