 Crust, p. 89. 



Carapace finely granular on the branchial regions, its length about 

 two- thirds its greatest breadth, its sides slightly convergent posteriorly 

 and cut anteriorly into 3 teeth, the first of which is the anterolateral 

 angle. 



Front only very moderately deflexed, its least breadth (between 

 the eyestalks) is about a fifth the greatest breadth of the carapace, very 

 obscurely bilobed. 



Orbits oblique, sinuous, their borders microscopically beaded. The 

 eyestalks project nearly half their length beyond the antero-lateral angles of 

 the carapace. 



The external maxillipeds, when the nagella are folded, completely 

 occlude the buccal cavern : the suture between the merus and ischium is 

 oblique. 



The legs are darkly variegated or incompletely banded, and are 

 unarmed except for a subterminal spine on the anterior border of the 

 meropodites of the first 3 pairs. 



The chelipeds in the young male are not as long as, though more 

 massive than, the 2nd and 3rd pairs of legs. 



In the Indian Museum are 4 specimens, more or less damaged, 

 from the Andamans and Mergui ("Investigator" collection). The 

 largest male (which wants the chelipeds) has a carapace 9 millim. long 

 and 14 millim. broad.

Carapace studded with large conspicuous pearly granules, its 

 length in the adult male is about six-elevenths of its greatest breadth 

 at the level of the second tooth of the lateral border : the lateral borders 

 are slightly but distinctly convergent posteriorly where they are beaded 

 or denticulate, anteriorly they are cut into three acute teeth the last of 

 "which is minute, the first being the outer orbital angle. 



The front, measured at its narrowest part between the eyestalks, is 

 barely a sixteenth the greatest breadth of the carapace : its free edge is 

 distinctly bilobed. Orbits sinuous, a little oblique ; their upper border
