finger and tip overlapping on the inner side of that of the lower 

 finger. The proximal area on the base of the upper finger is 

 dorsally flattened, and with a distinctive circular spot that fits 

 against an opposed circular area on the distal margin of the palm, 

 when the finger is wide open. The lateral surfaces of both fingers 

 are beset with numerous long bristles, the surfaces of the palms 

 being more sparsely setose. 



The second right leg measures: ischium, 2 mm. long; merus, 

 4 mm. long; carpus : first joint, 2 mm. ; second joint, 1 mm. ; third 

 joint, 0.6 mm.; fourth joint, 0.7 mm.; fifth joint, 1.5 mm. long; 

 propodus, 1.4 mm., the palm being 0.75 mm. and finger 0.65 mm. 

 long. The upper and lower lateral margins of both fingers are 

 bristling with long setae and there are a few short setae on the 

 cutting edges of both fingers. 



The second left leg, on the same side as the largest first cheli- 

 ped, measures: ischium, 2 mm. long; merus, 4 mm. long; carpus, 

 first joint, 2 mm. long; second joint, 1 mm.; third joint, 1 mm.; 

 fourth joint, 1 mm. ; fifth joint, 1.45 mm. long ; propodus, 1.5 mm., 

 the palm being 0.75 mm. and the finger 0.65 mm. long, with the 

 distal and lateral margins of these fingers carrying a much heavier 

 brush of setae than occur on the opposite second hand. 



The third leg has the ischium short, obliquely produced dis- 

 tally, supporting the merus; the merus is 1.8 mm. wide in the 

 median region and 5 mm. long ; the carpus is slenderer, laterally 

 compressed, 2.5 mm. long ; the propodus is 3 mm. long, more com- 

 pressed laterally, 1 mm. median width, armed on the inferior lat- 

 eral margin with a series of six strong, articulated spines sub- 

 equally spaced, plus a seventh similar spine beside the distal sixth 

 spine ; the dactyl is 1.5 mm. long, stout, with blunted, weakly bifid 

 tip caused by the termination of the longitudinal sulcus of the 

 outer lateral face; the ventral-lateral surface is slightly swollen 

 and has the external surface microscopically corrugated. 



The fourth pair of legs is similar to the third pair, but is 

 shorter and extend only to about midway the propodal joint of the 

 preceding pair. 



The fifth pair of legs is quite slender and extend only to the 

 base of the propodus of the third pair. The dactyli of the fourth 

 and fifth pairs of legs are less conspicuously bifid at the tips, but the 

 ventral-lateral surface is similarly channelled.
