anterior, and lower surface coarsely granular; upper crest of brachium 

 coarsely granular, the posterior surface with a few granules and some 

 semicircular elevations round the bases of the hairs along the middle ; 

 hands pilose, slightly convex above and covered with lo\v rounded 

 elevations ; finger-keel strong and nearly smooth ; the secondary 

 keels weak, granular, marked with black lines ; inner edge of hand 

 denticulate ; width of hand equal to the length of hand-back. 



Legs with lower edge of femora coarsely granular, anterior surface 

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

 with no external and 5-6 internal spines below, in addition to the 

 3 external and 4 internal spines on the terminal lobes ; tarsi of the 

 third pair with a minute or no external and 4-5 internal spines below, 

 in addition to the 4 external and 5 internal spines on the terminal 

 lobes ; the superior process as long as the lateral lobes. 



Operculum transversely oval, much broader than long, completely 

 cleft longitudinally. 



Pectincs with 13-15 teeth, scape rounded at the base behind and 

 free of teeth for one-third of its length. 



Measurements in Millimetres. Total length 97 ; greatest length of 

 carapace 14 ; width of carapace 12 ; distance of eyes from anterior 

 median edge 9i ; width of hand 7i ; length of hand-back 7i, of 

 movable finger 13, of tail 56 ; width of first caudal segment 5^-, of 

 fifth caudal segment 4. 



Female (recently killed, in alcohol). 



Differs from the male in the following characters : 



Colour. The humerus and brachium in some specimens more or 

 less blackened. 



Carapace as long as the first and second caudal segment and half 

 the third. 



Terfja. Segments 1-6 shiny, smooth or roughened in the middle, 

 finely granular at the sides, the granulated area increasing in the 

 posterior segments ; median keel smooth. 



Sterna. Segments 1-4 smooth and polished ; segment 5 weakly 

 and evenly granular, smooth only along the anterior border, the 

 granules more numerous than in the female of 0. granifrons, Pocock. 



Cauda rather weak ; infero-lateral crests sometimes weakly 

 developed in segment 1 ; under surface of segments 1 and 2 

 weakly granular, like the last segment of the sterna. 



PaZps. Hands broad, robust, cordate at base, strongly convex 

 above ; the inner part of the upper surface thickly covered with low 

 rounded granules ; secondary keels weak, composed of a row of
