The 2nd joint of tlie antenna-peduncle is not produced or acute at the 

 antero-external angle ; the antennal flagellum is much longer than the carapace. 



Chelipeds (in the adult female and young male) short, just reaching beyond 

 the end of the carpus of the first pair of legs : the arm is slenderer than the 

 corresponding joint of the first three pair of legs : the fingers are longer than 

 the hands : none of the joints are spinate. 



The second and third ambulatory legs, which are longer than the first by 

 their dactylus, and longer than the fourth by their merus and dactylus, are 3 

 times the length of the carapace. In the first three pair the anterior border of 

 the meropodite is armed with large spines, but the other joints are unarmed : 

 the dactylus is slender, curved, and of great length, being hardly shorter than 

 the preceding joint. 



In the subchehform, dorsal, fourth (last) pair the anterior border of the 

 merus ends in a spine and the posterior border of the merus is spiny through- 

 out, the propodite is much dilated and toothed at its basal angle posteriorly, so 

 as to be ^shaped, and has one or two spines on the undilated portion of its 

 posterior border, and the dactylus is short and is toothed along the posterior 

 border. 



The carapace of an adult female is 45 millim. long and 43"5 millim. broad. 



The colours in life vary from red to bluish-pink.
