Process of clypeus large, seen vertically from below covering 

 the whole area between the mandibular palps. 



Antennulse rather similar in both sexes, reaching to the anterior 

 lateral angle of thorax. Peduncle moderately thick, its third 

 joint a little louger than the second. Plagelluiu in the male 

 with the first joint thick, considerably longer than the third 

 joint of the peduncle, scarcely twice as long as the distal joints 

 of flagellum combined and furnished with a large nuinber of 

 rather short sensory hairs ; in the female the first joint of 

 flagellum is shorter and more slender, yet somewhat longer than 

 third joint of the peduncle ; in both sexes the second joint is about 

 as long as thick, longer than the third ; terminal setse very short. 

 Peduncle of antennae with the penultimate joint at most half 

 as long as the terminal one. 



Epimera of second to fifth thoracic segments not produced into 

 processes ; those of sixth segment with a moderately long 

 process ; epimera of seventh segment with rather small processes. 

 Seventh thoracic legs broader than in any other species. 

 Eourth joint only a little longer than broad and somewhat 

 shorter than the fifth ; both these joints on the lower surfact- 

 with some spines rather removed from the inner margin and 

 some spines rather near the outer margin. 



Last abdominal segment has on its upper surface a deep 

 transverse, but yet not broad impression, the anterior margin of 

 which is considerably curved, and besides a pair of sublateral,. 

 conspicuous, irregular impressions not connected with the central 

 one. Posterior margin at most a little more than one-third as 

 long as the breadth of the segment, rather convex, finely serrate^ 

 without any distinct tooth at the ends, but armed with two pairs- 

 of movable spines ; the spines on each half somewhat distant 

 from each other.
