The peduncle of the outer antenna is a little longer than the eye. 

 The lower margin of the ischium of the left cheliped has a row of 3 

 molariform tubercles. Lower inner margin of ischium and merus 

 armed with stout irregular spines, one at the proximal end of merus 

 much the strongest. Outer margin of merus denticulate; from this 

 margin a short row of tubercles extends along lower surface; upper 

 margin squamose, a terminal spine. Carpus spinose; 4: spines on inner 

 margin, ■! smaller on anterior margin; 2 oblique intermediate rows, one 

 of 5 spines terminating at inner distal angle, the other of 3 spines; 

 lower distal margin in part cristiform and denticulate. 



The depth of the palm is greater than its width; lower margin 

 marked by a sinuous line of strong molariform tubercles; lower half 

 of outer surface nearly smooth, densely punctate, and with fine 

 granules near the margins; upper half of surface armed with tubercles 

 arranged for the most part in -1 or 5 longitudinal rows, with some 

 granules interspersed; near the upper margin they become stronger,
