the last subgranular in the middle, more coarsely granular at the 

 sides and furnished with a pair of short granular crests. Sterna 

 smooth and polished ; the last not crested. Tail less than three 

 and a half times as long as carapace, upper surface smooth, lateral 

 surface only weakly granular ; superior and inferior lateral crests 

 denticulate, inferior keels of 4th weakly denticulate, superior lateral 

 crest of 5th rectangular but only subdenticulate ; vesicle smooth or 

 almost smooth at the sides. Chelce with humerus weakly granular 

 in its basal half above ; the upper and anterior surface bounded by 

 strongly denticulate crests, the anterior surface with a few large 

 tubercles ; lower surface lightly reticulated mesially, with long 

 finely granular posterior crest ; brachium shorter than carapace, 

 armed in front at base with siugle long spine, posterior surface 

 smooth ; hand thick, strongly convex above, its inner edge not 

 so compressed as in the Indian species, the width less than length 

 of uuderhand, which is about three-fourths the length of the 

 movable finger ; dorsal surface of hand smooth, punctured and 

 obsoletely reticulated, weakly carinate, the reticulation becoming 

 coarser toward the inner edge, which is itself somewhat thickly 

 and coarsely granular; immovable finger with smooth keel. 

 Penultimate fang of the movable ringer of the mandibles longer 

 than in the foregoing species. Tarsal spine-armature 7 or 6 behind, 

 4 in front. Pectinal teeth about 14-16 ( d , 2 )• 



d . Tail a little and chehe very much longer than in the female ; 

 tail not quite four times as long as carapace, which is shorter

 brachium much longer than carapace ; hand very long and slender, 

 nearly parallel-sided, the width half the length of the uuderhand, 

 which is longer than carapace and almost as long as the movable 

 finger.
