and considerably longer, extending almost to the posterior margin 

 of the carapace. The branchiostegal angle is sharp and reaches 

 the level of the rostral apex. On the margin immediately beneath 

 it is a small spinnle. 



The basal segment of the antennular peduncle (text-fig. 3a) is 

 broad, its outer distal angle is bluntly produced. The lateral pro- 

 cess is transversely oval with a straight posterior margin and a 

 sharp point at its antero-external angle. The antennal scale (text- 

 fig. 3^) is broad, not more than two and a third times as long as 

 wide; the outer margin is a trifle sinuous and terminates in a sharp 

 spine which does not reach nearly as far forwards as the distal end 

 of the lamella. 



The third maxillipedes reach a little beyond the end of the

antennal scale ; the ultimate segment is decidedly longer than the 

 antepenultimate. 



The first peraeopods (text-fig. ^c) reach a little beyond the 

 third maxillipede and do not possess an exopod. The outer edge 

 of the merus terminates in a single stout tooth and the margin 

 between this tooth and the carpal articulation is entire. The 

 carpus bears two spines on its outer distal margin. The subchela 

 is little more than two and a half times as long as wide ; the cut- 

 ting margin is strongly oblique and the spine which forms the 

 ' thumb' is extremely long and slender and is remarkable in that 

 it is articulated and movable. The first legs are not separated at 

 their base by the forwardly directed sternal tooth found in some 

 other species of the genus. 



The second peraeopods (text -fig. -^d) reach beyond the carpus 

 of the first pair and are lightly clothed with hair. The merus is
