Outer surface of wrist nodular : a few nodules on upper liorder of palm : 

 fingers short and stout. 



The carpus and propodite of the first 2 pair of legs are nodular. 



Last 2 pair of legs short and slender, not nodular, not much more than half 

 the length of the first 2 pair : the 4th (last) pair very little longer than the 3rd, 

 Both end in a strong claw-like dactylus, but are hardly cheliform, although there 

 is a small spine at the end of the propodite of each.

Body covered with a short tomentum. 



Carapace about as long as broad, convex, smooth, the cervical groove distinct. 

 Front cut into 3 acute rather slender teeth, the middle one of which is on a 

 lower plane and slenderer than the others. An acute spine near the middle of 

 the upper border of the orbit marks the position of the true inner supra- 

 orbital angle. Outer orbital angle spiniform. Suborbital lobe dentiform, faii-ly 

 |)rominent. 



True antero- lateral borders of the carapace cut into 2 teeth, the anterior 

 being much the larger and spine-like. In the gap between the 1st tooth and 

 the onter orbital angle two small smooth subhepatic tubercles are visible, one 

 below the other. 



An elegant pearl-liJce tubercle below fhem(b-orbif 1(1 lolii', a similar but .smnthr 

 tnhcrde in the middle of the ventral surface of the merm of, the external maxillipeds 

 and another in the middle of the ventral surface of the second joint of the antennal 

 peduncle, are characteristic. 



An extremely inconspicuous denticle on the postero-lateral border, ])ehiud
