Colour a tolerably uniform yellow, the legs and chelae clearer 

 than the trunk ; tail with its 5th segment and vesicle pale greenish 

 or brownish black, the dark pigment spreading on to the sides and 

 lower surface of the 4th. Carapace coarsely granular, the area 

 between the anterior and posterior keels smoother than the sides ; 

 anterior keels and superciliary crests granular, posterior keels- 

 running in the same direction as the median keels but not quite 

 meeting them. Ten/a coarsely granular ; lateral keels obsolete on 

 the anterior segments. Sterna weakly granular laterally, the last 

 with four granular crests. Tail powerful, with strongly elevated 

 dorsal keels, increasing in width to the middle of the 3rd segment 

 (which is as wide as long), the 4th either slightly narrower than 

 the 3rd ( 2 ) or equalling it in width ( 6 ) ; normal keels well 

 developed and granular, the superior keels of segments 1-4 ending 

 in a dentiform tubercle ; median lateral keel represented by only 

 a few granules on the 2nd segment ; inferior and lateral inter- 

 carinal spaces finely but not closely granular ; 5th segment with 

 superior keels high and compressed, granules of inferior lateral 

 keels becoming gradually dentiform posteriorly ; vesicle small, 

 granular. Chelae with granular crests and granular intercarpal 

 spaces on humerus and brachium ; hand smooth, its width in adidt 

 equal to length of underhand, which is about half the length of 

 the movable digit ; the latter basally lobate, about as long as the 

 carapace and furnished with 13 rows of teeth. Legs distally 

 hairy ; lower side of tarsi naked or furnished with a single row of 

 bristles. Pectinal teeth ( 2 ) about 23, (j) about 30. Length up

Closely resembling the preceding in colour and structure, but 

 with much more black round the ocular tubercle and in the middle 

 of the depression behind it ; the anterior surface, too, of the 

 brachium is infuscate above, and the superior crest of the anterior 

 surface of the humerus also; the extremity of the femur of the 

 legs and the front of the patella usually lightly infuscate.
