 shorter spines on the branchial region, a tubercular eminence 

 towards its posterior boundary. Rostral cornua slender, acute, 

 divergent from their base, two-thirds of the length of the 

 carapace. Spine at the antero-external angle of the base of the

 situated below the orbit, arising from the base of the antennas ; 

 another much shorter immediately on the outer side of the orifice 

 of the green gland. Anterior legs as long as the carapace, slender, 

 sub-cylindrical ; third joint with a small spine' at the distal end 

 of its upper surface ; hand very slightly dilated in the male.
