A. TERAO : 



well-calcified portion in front of the cervical groove is broader than 

 long, its length in the median line being equal to about eight-ninths 

 of the greatest breadth. Rostrum broad but not rounded off, slightly 

 prominent, weakly carinated. Left antero-lateral angle tipped with a 

 small tooth, which is absent on the right. 



Eyestalks slightly setose dorsally, broadened distally and slightly 

 inflated at base, half as long as the front border of carapace, reaching 

 far beyond the first joint of antennular peduncle and the penultimate 

 joint of antennal peduncle. Eyes large ; ophthalmic scales simple, acute. 



Antennular peduncles slightly compressed, as long as the anterior 

 border of carapace, the terminal joint shorter than half their total 

 length ; upper flagellum nearly as long as the terminal joint. 



Antennal peduncles stout, reaching a short way beyond the end 

 of the second' joint of antennular pendimele ; acicles long, reaching to 

 the middle of the terminal joint of antennal peduncle, curved, setose, 

 faintly serrulate along the inner edge ; flagellum wanting. 



Right cheliped much larger than the left, nearly three times as 

 long as carapace, more or less copiously covered all over with long 

 soft hairs, which are densest on merus and upper surface of chela ; 

 chela ovato-lanceolate, all other joints elongate ; carpus as long as 

 palm and longer than merus ; dactylus slightly shorter than palm ; 

 upper and lower borders of palm granulous. 



The slender left cheliped reaches almost to base of dactylus of 

 the right cheliped ; all joints covered with long soft hairs ; merus as 

 long as carpus and longer than palm ; dactylus longer than palm ; 

 with about twenty irregularly disposed granules on the upper border 

 of carpus and a few sparsely set granules on the lower border of 

 palm ; under surface of merus and ischium granulous. 



Second and third pairs of legs compressed, with a tiny spintile at 

 the distal end of the anterior border of carpus. Merus of the second 

 pair of legs has the lower border well-defined ; ischium with a number 

 of granules on the lower border.
