This species is distinguished by its six-lobed front and by its very minute fourth 

 antero-lateral spine. The chelipedes are crossed by strigose lines, which are specially 

 noticeable on the upper and distal surface of the merits, tbe under surface of the 

 propodus, and which are even seen on the inner surface of the latter joint ; similar 

 pubescent lines are also met with running longitudinally on the ambulatory legs. The 

 sternal region, anteriorly and at the sides, is seen with a lens to be very finely 

 granulated. In Miers's figure the last antero-lateral spine is more prominent than in my 

 specimen, the fingers are longer in relation to the palm, and of the two spines on the 

 upper margin of the palm the posterior one is much larger than the anterior, while 

 in the Tuticorin example it is only slightly larger. These differences are, however, 

 probably not of much importance. 



The carapace is 8 mm. long and 10"5 mm. broad.
