1st pair of thoracic legs stout, reaching a little beyond the antennal scale, 

 even when the dactylus is flexed : the merus and the exceedingly short carpus 

 each have a very strong spine at the far end of their ventral border. 



The 2nd pair of legs, in both sexes, reach nearly halfway along the propod- 

 ite of the 1st pair. The 3rd pair reach beyond the antennal scale by nearly 

 their two terminal joints : there is a long acicular spine on the sternum between 

 their bases. The 4th and 5th pair, which end in vertically-compressed, almost 

 palmulate, dactyli, are of good length, the 4th pair reaching nearly to the tip of 

 the antennal scale. 



Colour in life chalky yellow, eyes dark. 



The carapace of the largest female is 20 millim., the abdomen 50 millim.. 

 measured in the middle line.

Differs from Ae. andamanense only in the following particulars, as far as the 

 female is concerned, the male being unknown : — 



The rostrum reaches a good way beyond the eyes, and the three spines on 

 either edge are larger, the one at the base being not decidedly remote from the 

 others : 



the lateral carina? of the carapace are only 3-toothed, and the supra- 

 marginal carinas are only 2 -toothed : 



the median carina of the 2nd abdominal tergum is unispinous ; all the 

 carina? of the 3rd and 4th abdominal terga, except the median one, are very 

 indistinct ; the two middle carina? of the 6th tergum have only one retrorse tooth 

 besides the terminal one. 



An egg-laden female has the carapace 13*5 millim. long, the abdomen 30 - 5 

 millim. long, measured in the middle line.
