The thoracic legs are slender, smooth or very faintly squamous and very 

 slightly hairy. The chelipeds vary in length in the male (in which sex they are 

 not quite equal) from one and a half times to twice the length of the fully 

 extended body : in the female they are between one and a third and one and a 

 half times the length of the body : the merus and carpus, and the propodite in 

 its palmar portion are covered with large thorns ; the fingers, which do not quite 

 equal the palm in length, are evenly and finely toothed, and the fixed finger 

 has also several distant spines along its outer margin, and at the base of 

 the terminal claw a pair of small teeth, between which the tip of the dactylus 

 closes. 



Of the second, third, and fourth thoracic legs the merus has both its margins 

 and the carpus its front margin thorny, the posterior margin of the carpus having 

 only a long terminal spine, while the propodite and dactylus have their posterior 

 edge serrated for a series of minute articulating spinules. 



The first pair of abdominal legs in the male have the usual development. 



Colour in life milky pink. 



In the largest male the length of the body is 45 millim., and that of the 

 longer cheliped 87 millim.

Differs from M. microps only in the structure of the chelipeds, which (in the 

 male) are markedly unequal, one (the right in one individual, the left in the other) 

 exceeding its fellow by nearly the whole length of the dactylus, both being much 

 longer than in typical M. microps. 



The chelipeds are very densely furred, except on the short ischium, and are 

 from nearly twice to two and a half times the length of the fully extended body 

 measured with the rostrum ; they are thorny, much as in M. microps, except that 

 the thorns are relatively smaller, especially on the propodite, and most of all on 

 the propodite of the larger cheliped, where they are almost entirely hidden in the 

 thick fur. The fingers are not much more than half the length of the palm ; 

 and while in the smaller claw they are straight, closely apposed, and otherwise 

 the same as in M. microps, in the larger claw they are separated throughout, but 

 especially at the base, where there is found on the dactylus a large truncated
