380 DE. W. T. CALMAN ON NEW OE EAEE 



The third and fourth pairs of legs have minute exopods, each of two segments. 

 The coxa of the third pair is broadened in an antero-posterior direction, its distal edge 

 is serrated, and the basis is attached near its posterior end ; the basis has a small 

 tooth on the anterior side at its distal end. The fifth pair of legs are much shorter 

 than the fourth. 



The peduncle of the uropods is a little more than half as long again as the telson, 

 and has about seven spines on the distal part of its inner edge ; the subequal rami are 

 a little longer than two-thirds of the peduncle. The endopod is distinctly divided into 

 three segments, the first longer than the other two together ; there are numerous 

 short spines on the inner edge, and the apical spine is short. The exopod bears setae 

 terminally and on the outer edge. 



Adult Male. — Total length 9 mm. 



The dorsal edge of the carapace is nearly straight and the pseudorostrum is hori- 

 zontal. The ocular lobe is slightly prominent on the dorsal surface as seen from the 

 side, but has no terminal tooth. The third and fourth leg-bearing somites are less 

 strongly produced backwards than in the female, and there is no marked interval 

 between the second and third pairs of legs. The last thoracic somite has the postero- 

 lateral corners produced as short spines. The ventral spine of the first abdominal 

 somite is bifid. The telson, which has the usual dorsal prominence, is about as long 

 as the last somite. 



The peduncle of theantennules has the terminal segment stouter than in the female, 

 and carrying a tuft of sensory filaments ; the outer flagellum has five and the inner 

 three segments, apart from a doubtful terminal segment in each case. 



The antennae have the usual structure ; the sensory filaments on the anterior surface 

 of the peduncle are very short ; the flagellum, broken in the specimen figured, appears 

 to be as long as the body. 



The second leg-s have the distal segments more elongated than in the female, to2;ether 

 hardly shorter than the basis ; the carpus is nearly twice as long as the merus ; the 

 propodus is stouter and longer than the dactylus, and the latter bears terminally 

 two small curved claws, which are absent in the female. In the third and fourth pairs 

 of legs the basis is produced into a strong tooth at its distal end anteriorly. In the 

 fourth and fifth pairs (but not in the third) the ischium is produced posteriorly in a 

 tooth-like process. 



Both pairs of pleopods are biramous, with the exopod of two segments. 



The exopod of the uropods is slightly shorter than the endopod ; there are numerous 

 spinules on the inner edge of the latter and of the peduncle.
