their position ; infero-median keels quite obsolete in segments 1-4 ; 

 the position of the two ventral pairs of keels on the first four seg- 

 ments is usually indicated by black lines or spots, which extend on 

 to the posterior sternite ; the whole ventral surface of the fourth 

 caudal segment is densely covered with fine rounded granules, slightly 

 larger than those on the anterior segments ; fifth caudal segment 

 three times as long as broad, sparsely granular at the sides and 

 below, the median keel weaker than the infero-lateral ones ; vesicle 

 smooth or minutely granular at the base below, sometimes with 

 longitudinal infuscate bands. 



Palps. All the crests of the humerus together with its upper, 

 anterior, and lower surfaces coarsely granular; upper crest of 

 brachium coarsely granular, the posterior surface sparsely so ; hands 

 hairy, slightly convex and coarsely granular above, the granules 

 conical and connected by a network of black pigment ; finger-keel 

 strong and granular, in its distal portion sometimes only crenulated ; 

 the secondary keels weak, granular, indicated by black lines ; inner 

 edge of hand denticulate ; width of hand exceeding length of hand- 

 back. 



Legs with the lower edge of femora coarsely granular, the anterior 

 surface of posterior femora finely granular ; tarsi of fourth pair of 

 legs with no external and 4-5 internal spines below, those of the 

 third pair of legs with 1-2 external and 4-5 internal spines below, in 

 addition to the 4 external and 5 internal spines on the terminal lobes ; 

 the superior process much shorter than the lateral lobes. 



Operculum transversely oval, much broader than long, completely 

 cleft longitudinally. 



Pectines with 11-15 teeth ; scape rounded at the base behind and 

 free of teeth for one-third of its length. 



Measurements in Millimetres. Total length 82 ; greatest length of 

 carapace 12 ; width of carapace 11 ; distance of eyes from anterior 

 median edge 8 ; width of hand 8 ; length of hand-back 6^, of movable 

 finger 10, of tail 49 ; width of first caudal segment 5^-, of fifth caudal 

 segment 4. 



Female (recently killed, in alcohol). 



Darker. 



Carapace, as long as the first and second caudal segment and one- 

 third of the third. 



Terga. Segments 1-6 smooth in the middle, finely granular at 

 the sides; segments 2-6 with smooth longitudinal keels. 



Sterna. All the segments smooth and polished. 



Can da slenderer, with the ventral surface of segment 1 smooth, of
