lower finger ; there is also a rounded, laminate, sub-basal crest on the 

 upper margin of this finger, beyond which the margin is coarsely 

 beaded. There is a distinct crescentic gape between these fingers, the 

 upper of which has its cutting edge smooth ; the lower finger has three 

 or four teeth, the tips interlock. The fingers of the left cheliped do 

 not gape and lack the huge node projections ; the upper finger is slen- 

 derer and has eight teeth, the lower finger has seven, in addition to 

 the tip. 



The ambulatories are slender, laterally compressed, the meral joint 

 dilated, much wider than the succeeding joints ; the dactyli are taper- 

 ing, acuminate, with several longitudinal grooves on the lateral faces. 

 When folded, the legs fit beneath the box-like cavity formed by the 

 wing-like expansion of the carapace and cheliped.
