 Chela of large male, external view. 



except for a small portion at the base of the stalk, is entirely con« 

 cealed from view. 



The chelipedes are greatly swollen in both sexes ; the chelae 

 of the male are much larger than those of the female. The outer 

 border of the merus 

 bears a conspicuous 

 tooth in front of its 

 middle point. On the 

 inner side of the carpus 

 there is a longitudinal 

 vtdge which is furnished 

 with a fringe of long 

 hairs. The chela of the 

 male (text-fig. 18) is 

 less than one and a 

 half times as long as 

 high. There are sharp 

 keels on both upper 

 and lower borders of the palm, the latter being continued to the 

 tip of the immobile finger. These keels like that on the carpus 

 are fringed with long hairs. The inner surface of the palm is con- 

 vex and the outer face bears a huge protuberance (text- fig. 19), 

 only well developed in very large males, which culminates in a 



short crest not far 

 form the finger cleft. 

 The fingers are stout 

 and in large individuals 

 meet only at the tips. 

 The dactylus bears two 

 large blunt teeth in its 

 basal half and the fixed 

 finger two smaller ones 

 placed just behind 

 them; nearer the tip 

 each finger bears four 

 or five teeth. The dactylus is fully one and a half times the length 

 of the upper border of the palm and is obscurely ridged dorsally. 

 The chela of the female is similar to that of the male, but is more 

 slender and shows practically no 

 trace of the large protuberance 

 on the palm. Except for the 

 fringes of hair already mentioned 

 the chelipede bears only a few fine 

 and scattered setae. 



The second walking legs are a 

 little longer than the first and 

 third and are about three times 



the length of the carapace; the last pair is only two-thirds the 

 length of the second. The anterior border of the merus in all four 

 l-)airs terminates in a hhint tooth. The dactyli are slender and
