terminal spine of the outer margin is very sharp and long, extend- 

 ing beyond the end of the second segment. The second and third 

 segments are broad and the length of the two combined is scarcely 

 more than half that of the basal segment. The free part of the 

 stouter of the two rami composing the outer flagellum is about 

 one-third the length of the fused basal portion, the latter com- 

 prising 6 segments. The total length of the shorter ramus is less 

 than that of the peduncle. 



The antennal scale (text-fig. 766) scarcely reaches beyond the 

 end of the antennular peduncle. It is only about 22 times as long 

 as broad and the outer margin, which is very slightly concave, ends 

 in a spine which reaches almost as far forwards as the broadly 

 rounded apex of the lamella. 



The third maxilliped (text-fig. 76c) bears a foliaceous epipod. 

 The exopod does not reach the end of the slightly curved ante- 

 penultimate segment. The ultimate segment is as long as the 

 penultimate. 



The first peraeopods are slender and reach beyond the anten- 

 nal scale by the chela and a portion of the carpus. The chela is a 

 little longer than the carpus and the merus a little longer than the 

 chela. The carpus is about 6 times as long as wide. The palm 

 is 4 times as long as wide and is twice as long as the fingers. The 

 fingers bear some short hairs, but their inner margins are unarmed. 



In the male specimen the second pair of peraeopods is very 

 unequal; in the female one leg only, apparently the larger of 

 the two, is present. 



The larger limb extend beyond the antennal scale by the whole 

 length of the chela and carpus and is covered with minute tuber- 

 cles. The merus is longer than the ischium and is broadest distally, 

 the lower border ending in a strong tooth. The carpus is very short, 

 scarcely longer than broad ; it is little more than one-third the 

 length of the merus and is unarmed. The chela is about 275 

 times the length of the merus; the palm is about 35 times as long 

 as wide and is from 22 to 2*5 times as long as the dactylus. The 

 dactylus is heavy, with strongly convex outer border (text- fig. y6d) ; 

 at the base of its inner margin it is provided with a large acute 

 tooth which fits into a cavity in the fixed finger. In front of this 

 cavity the fixed finger bears a small tooth. In the distal two- 

 thirds of their length the inner margin of each finger is entire, 

 the margin is, however, a little concave with the result that a 

 small gap is left when the claw is closed. The tips are inturned 

 and cross one another. 



In the smaller second leg the tooth at the distal end of the 

 merus appears to be absent and the carpus is nearly twice as long 

 as wide and rather less than half the length of the merus. The 

 chela is 165 times the length of the merus, with fingers unarmed 

 and slightly less than half the length of the palm. 



The three posterior peraeopods are stout ; the third reach beyond 

 the antennal scale by the length of the dactylus. The merus is 

 about 4 - 5 times as long as broad and is 2 - 3 times the length of the car-
