13'2 CRUSTACKANS OF THE 



Umdisch Ost-Indien, T. Il, 1892, p. 290) the cephalothorax 

 of this species appears also somewhat longer in pro- 

 portion to its breadth than that of Pot. hicristatum., the 

 upper surface is somewhat granular near the antero- 

 lateral margin and probably not ornamented with the 

 ridge-like traces of the post-frontal crest that are charac- 

 teristic of the species of Mount Liang-Koeboeng : no doubt 

 still many other differences exist.
