weak keel and a shallow depression between this and the lateral 

 edge on each side behind. 



Cauda long, its upper surface granular in the anterior segments, 

 smooth or nearly so in the posterior ones ; upper crests granular, the 

 terminal tooth not enlarged nor spiniform ; upper lateral crests well 

 developed, granular, absent from the posterior half of the fifth 

 segment ; infero-lateral and median crests distinct and smooth or 

 nearly so on the anterior segments, granular on the fourth, and 

 serrated on the fifth ; sides of the cauda minutely and sparsely 

 granular in the lower part, somewhat more coarsely so in the upper 

 part ; under surface smooth in segments 1 and 2, with a few minute 

 granules in segments 3 and 4, and rather coarsely granular in 

 segment 5 between the crests ; vesicle with a few minute granules 

 at the base below. Cauda four times the length of the carapace, 

 rather slender ; width of the first segment equal to its length along 

 the upper median line, width of the second segment considerably 

 less than the length along this line ; length of fifth segment con- 

 siderably exceeding the breadth of the hand. 



Palps. Crests of the humerus, its upper, anterior, and lower 

 surfaces coarsely granular, the upper anterior crest strong, com- 

 posed of a row of coarse granules. Upper crest of brachium weakly 

 crenulated, nearly smooth in places ; the posterior surface roughened, 

 with several longitudinal, roughened crests. Hands broad, robust, 

 cordate at base ; inner part of upper surface moderately convex, 

 thickly covered with low, rounded, anastomosing, punctated eleva- 

 tions, and ornamented with a network of black pigment ; the 

 secondary keels represented by two black lines ; outer part of 

 upper surface of hands densely and coarsely granular, without 

 secondary keel ; finger-keel strong and smooth ; inner edge of 

 hand bluntly granular. 



Legs. Anterior surface of femora minutely granular, lower edge 

 of three anterior femora more coarsely granular. Tarsi of the third 

 and fourth 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 ; these lobes scarcely or not much longer than the 

 well-developed superior process. 



Operculum sub-triangular, much broader than long, emarginate 

 posteriorly, but not cleft, longitudinally. 



Pcctines with 12 teeth (14 in the young female), scape rounded at 

 the base behind and free of teeth for about one-third of its length. 



Measurements in Millimetres. Total length 90 ; length of carapace 

 12f ; width of carapace 12i ; distance of eyes from anterior margin 8 ;
