138 CRUSTACEANS OF THE 



first pair of legs project with two fifth of the wrist beyond 

 the end of the antennal scales. The second pair of legs 

 are almost as long as the body, measuring 215 mm. and 

 they project with the whole wrist beyond the antennal 

 scales. The wrist (45 mm.) has exactly the same length 

 as the palm , the fingers are slightly shorter and the mobile 

 finger is covered with hairs. 



In the specimens from Pontianak, measuring 150 resp. 

 130 mm. from the apex of the rostrum to the tip of the 

 telson , the carpus of the second pair of legs is also still shorter 

 than the whole hand , as could be expected , because the 

 hand is shorter than the carpus only in those individuals 

 the length of which is smaller than about 105 mm., as I 

 have indicated in the paper quoted above. 



The carapace is smooth. In both specimens the rostrum 

 extends a little beyond the antennal scales and is armed 

 with 14 teeth on the upper and with 13 on the lower 

 margin ; in both the first three teeth are placed on the 

 cephalothorax. The second pair of legs have the following 

 measurements :

 Museums, II, p. 697), presenting on each side two minute 

 spiuules that by far do not reach to the apex. In the other 

 the apex of the telson is broken.
