CUUSTACKA — WHITKLK(;GK. 175 



gijuuilos ; inner surfaec finely i^ranulose, and longitiulinally exca- 

 vated in its ui)})er lialf. Fiiij^ers acute, crossed and calcareous at 

 the tips, tlieir inner edges unevenly denticulate and almost in 

 contact throughout wlien closed. The mobile finger is subvert ical 

 and nearly at right angles to the upper border when closed, its 

 length being nearly equal to the truncated extremities of the 

 palm and the ill-defined lower finger. 



Loft chelipede small, slender ; merus joint compressed, smootli ; 

 superior border acute, with a single line of setje ; outer asi>ect of 

 inferior border with a short denticulated crest. Carpus elongate, 

 a little compressed proximally, becoming subtrigonus distally ; 

 inner surface smooth, slightly setose, outer distally granulosa 

 and setose ; lower border rounded, upper angular, with a line of 

 subspiniform granules and a small spine at its distal extremity ; 

 there is also a small spine on the lower half of the distal margin. 



Hand compressed, equal to the carpus in length, breadth and 

 depth ; palm as long as the mobile finger ; the inner surface is 

 smooth and has a ridge-like elevation which is continuous with the 

 inner angular side of the lower finger ; external surface longitu- 

 dinally but indistinctly bisulcate, with three or four rows of 

 granules, of which those situated on the external aspect of the 

 upper surface are the largest. 



Fingers long, acute and corneous at the tips ; external surfaces 

 rounded, punctate and slightly setose, internal surfaces 

 longitudinally excavated to the acute inner edges ; the loyver 

 finger is slightly bent downwards and inclined inwards towards 

 the extremity. 



Ambulatory legs moderatelj^ elongate, subequal, smooth, com- 

 pressed and sparsely hairy ; the hairs are short, and mostly 

 confined to the upper borders of the joints. The merus joint is 

 equal in length to the propodus, and a little longer than the 

 carpus ; the superior border of the latter terminates in a small 

 spinule. 



Tarsus as long as the carpus and propodus combined, curved, 

 compressed and laterally grooved at the base ; upper and lower 

 external borders punctate and shortly setose. 



The fourth pair of legs is subchelate ; the rasp consists of a 

 linear series of fifteen scales, occupying about four-fifths of the 

 distal margin ; all the joints are more or less fringed with long 

 curved hairs. 



The fifth pair of legs is also similarly fringed with long hairs ; 

 the rasp is oblong in shape, and there are about six scales in each 

 row. 



There is only one external genital opening — it is situated on 

 the coxal joint of the third left leg.
