Differential characters : 



Colour of the palps lighter. 



Carapace considerably shorter than the first two caudal segments 

 taken together, the granulation of the sides less coarse, and the area 

 round the eye -tubercle rougher than in the female. 



Tcrya not shiny, densely covered with an exceedingly minute 

 granulation, the last segment only with coarse granulation towards 

 the sides. 



Sterna. Segments 1-4 minutely granular at the extreme lateral 

 borders, fifth segment scarcely roughened in the lateral part, smooth 

 in the middle. 



Gaud a long, 4f times the length of the carapace, rather slender, 

 scarcely stouter than in the female ; width of first caudal segment 

 slightly less than its length along the upper median line ; length of 

 fifth segment considerably exceeding the length of carapace. 



Palps. All the segments longer ; under side of humerus less 

 granular. Hands very pilose, much slenderer than in the female, 

 the fingers very long ; inner part of upper surface nearly flat, con- 

 cave distally, nearly smooth, the numerous elevations being scarcely 

 perceptibly raised, the secondary keels absent, except quite distally ; 

 inner edge of upper surface denticulate ; outer part of upper surface 

 of hand with some granules along the middle and alongside of lower 

 edge, otherwise nearly smooth ; breadth of hand equal to the length 

 of hand-back. 



Operculum transverse, much broader than long, completely cleft 

 longitudinally. 



Pectines with 1H teeth (17-18 in the young male), the scape 

 rectangular at base behind and therefore toothed along its whole 

 length.
