 has tubercles similar to those on the propodos. 



licft ch(!li})(!do more hairy and nuu;li suiiillnr tlian tho 

 right ; carpos with a few spities on its upper niarf^in ; these 

 become very strong at the distal end ; propodos with a very 

 strongly serrated crest along the outer side, and another much 

 less produced and curved along tlio lower margin ; tho dac- 

 tylos is two-thirds as long as the propodos, is sliglitly curved, 

 and only impinges against the latter at its apex. 



Ambulalory legs long ajid sparingly furnished with hairs, 

 the dactyli of botli pairs fuinislied on their lower edge with a 

 row of pectinate spities. 



CJolour : My spirit specimens are more or less striped and 

 mai-ked with r(;d and white, tlie markings being vcsry promi- 

 nent in longitudinal lines on the amhidalory legs.

Ocular peduncles slender, scarcely dilated at the end,

Chelipedes very unecpuil in si/e. 



Kight chelipede with meros compressed and rounded
