merus and considerably shorter than the palm, there are a few spinules on 

 its inner border and sometimes on its distal border also, and there may be 

 a few inconspicuous granules scattered on its outer surface : the palm much 

 increases in breadth distally, but its greatest breadth is less than its length ; 

 its upper border is not well defined, but the lower border is sharply defined, 

 subcristiform, curved and finely beaded ; its outer surface is more or less 

 studded with inconspicuous granules, especially in its lower half; its inner 

 surface is crossed diagonally by a strong ridge : the fingers are com- 

 pressed, the dactylus, which is slightly longer than the fixed finger, is nearly 

 as long as the upper border of the palm. 



Left cheliped very slender, not reaching base of dactylus of right ; 

 lower border of merus and upper border of carpus spinose : carpus as long 

 as or longer than hand (fingers included) ; palm longer than fingers. 



and and 3rd legs slender, smooth, reaching or slightly surpassing the 

 tip of the larger cheliped : the dactyli are about twice as long as the two 

 preceding joints combined, and the distal half of their concave border has 

 some long capillary spinelets. 



Colours in spirit : yellow, with fine blood-red longitudinal stripes : 

 the stripes extend along the whole length of both surfaces of the 2nd and 

 3rd legs and left cheliped, but are found only on the inner and upper surface 

 of the merus and inner surface of the carpus of the right cheliped : they 

 occur also on the upper surface of the antennal peduncle and acicle, and 

 on the anterior part of the carapace : the antennal flagellum is finely cross- 

 banded with dark red, and sometimes the outer surface of the wrist and 

 hand are finely spotted with red. Henderson regards this colouration as 

 protective, since it resembles the ramuli of a Hydroid. 



Length of carapace nearly 8 millim., but an egg-laden female is smaller.

A variety from the Andamans is characterized by having the whole outer 

 surface of the right carpus and hand finely granular, and the upper surface 

 of the left wrist and palm ornamented with granules or spinules that tend 

 to form longitudinal series.
