Eyestalks stoutish, slightly curved, exactly (sometimes barely) as long 

 as the front border of the carapace, longer than the peduncles of the anten- 

 nules, which latter are longer than those of the antennae : ophthalmic scales 

 acute. 



Antennal acicle stout, nearly reaching the end of the penultimate joint 

 of the peduncle, both its upper borders serrated : flagellum stout, and little 

 longer than the carapace. 



Both chelipeds are smooth and unarmed, with the edges of all the joints 

 entire. The left, which is vastly more massive than the right, is about half 

 again as long as the carapace : there is an oblique groove across the near end 

 of the outer surface of its carpus : its merus is slightly higher than long, its 

 carpus and palm much higher than long, its dactylus about as long as the 

 palm : there are a few small short tufts of bristles on the opposed edges of 

 its fingers, which meet throughout their extent, as well as a few setae on the 

 finders of the smaller hand, but otherwise the chelipeds are quite bare on 

 the extensor surface. Sometimes there are some sm.ooth subsquamiform 

 markings at the lower part of the inner surface of the left (enlarged) 

 hand. 



The 2nd and 3rd legs of both sides are considerably shorter than the 

 larger cheliped : their joints are smooth and unarmed, except for a spinule 

 at the far end of the anterior border of the carpus : the dactyli are much 

 shorter than the propodites. There are a few small tufts of set?e on the dac- 

 tyli and perhaps at the extreme end of the propodites, but nothing like a 

 thick brush. 



Colours in spirit somewhat variable : in general (even in specimens that 

 have been in spirit for 15 years in this climate) the anterior part of the 

 carapace is some shade of stone-blue, and both chelipeds up to the end of 

 the carpus are blue-black : the upper part of the hand and the near corner of 

 the dactylus of the large cheliped, and the whole of the palm of the small 

 cheliped, are of the same blue-black colour, but more or less of the left palm 

 and fingers are white, and the fingers of the right cheliped are reddish or 

 purplish at base and white at tip. The 2nd and 3rd legs have the joints up 

 to and including the propodite, some shade of red or orange, and a median 

 longitudinal band (with more or less of a second band below it) of 

 darker red or brown along the merus and carpus : the dactyli are white, 

 with red spot and cross-band, and black claws. The basal third of the 

 eyestalks is blue, the distal two-thirds orange. The antennae are orange or 

 yellow. 



Length of carapace 19 millim
