104 " ENDEAVOUR SCIENTIFIC RESULTS. 



Legs granulous, the three principal segments short and 

 broad ; dactyli hairy between the granules. 



Remarks. This is not a typical Xantho in all respects, 

 it is too convex at its middle, and the front too deflexed, 

 and uncommonly narrow. On the other hand, the orbits 

 and antennae are typical, the flagellum not excluded from 

 the orbit.

A series of eight specimens, the three largest of which 

 are 140 mm. wide or a little smaller, and the remainder 

 graduated down to one 12.3 mm. wide. In small specimens 

 the carapace is roughly granular except in the furrows; 

 the granules on the inner and outer surfaces of the hand 

 tend to form more or less distinct rows. All the spines on 

 the carapace and legs are much more acute than in larger 

 examples; in carapaces under 40 mm. wide, four of the 

 lateral spines are much more developed than the inter- 

 mediate ones, and the third and fourth large spines, or 

 those near the widest part of the carapace are longest. The 

 teeth on both fingers are proportionately larger. The 

 chelipeds are subequal in size though the right is the larger.
