Carapace longer than broad, convex, smooth, without distinction of regions. 

 €ervical groove broad and shallow. 



Front cut into 3 teeth, the lateral ones broad and triangular, the middle 

 one so small and deflexed as to be little visible in a dorsal view. 



There is no distinct tooth in the upper border of the orbit, but only an 

 angular bulge, to mark the position of the inner supra-orbital angle. Outer 

 orbital angle and sub-orbital lobe subdentiform. 



The antero-lateral borders of the carapace are smooth and entire, but as 

 they bend sharply inwards towards the orbits their anterior angle forms a 

 forwardly-directed tooth, the space between which and the outer-orbital angle 

 is concave. 



A very small prominence on the postero-lateral border, just behind the 

 branchial or cervical groove. 



The chelipeds and legs have an uneven surface, but are not really nodular, 

 though both the inner and outer angles of the winst are strongly pronounced. 



The last 2 pair of legs are short and slender, the 4th (last) pair being very 

 little longer than the 3rd ; both end in stout claw-like dactyli but are not 

 markedly cheliform. 



The abdomen bends in very sharply from tlie -Itli segment, making the 

 under surface of the body very flat. 



The carapace of the larger of the two Indian Museum specimens is 

 12 millim. long, and nearly 12 milhm. broad. 



Distribution : Persian Gulf, East Indian Archipelago.

Front longitudinally grooved, cut into 3 serrulate teeth, the middle one of 

 which is slender and prominent, while the lateral ones are broadly-triangular 

 and little prominent. 



Upper border of orbit serrulate, very oblique, devoid of any tooth or spine. 

 Outer orbital angle and suborbital lobe not salient.
