 spine ; telson little shorter than the 6th somite. Endopodite shorter 

 than the telson, rounded apically, a little more than half as broad 

 as long. Exopodite a little longer than the telson, truncate api- 

 cally, once and a half as long as broad; additional row of bristles 

 almost reaching to the middle of the apical border, diverging 

 very little from it.

 spines, the upper one near the base. Carpus a little shorter than 

 merus. Palm once and a half as long as the carpus and once

 to that of the larger; carpus slender, somewhat longer than the 

 merus, 4-times as long as broad ; chela a little longer than the
