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 spinule. 
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 anda 
sharp point at its antero-external angle. The antennal scale (text- 
fig. 3b) 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. 3c) 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 tootn 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. 3¢) reach beyond the carpus 
of the first pair and are lightly clothed with hair. The merus is
