The 2nd and 3rd legs barely reach the end of the right cheliped ; the 

 anterior border of the merus, carpus and propodite is distantly but distinctly 

 serrulate, and there are some spinules at the distal end of the posterior 

 border of the merus of the 2nd pair.

Differs from the type only in the form of the right cheliped, which is 

 shorter in all its joints and especially in the palm. 



In the right cheliped of the male the carpus is only as long as the com- 

 bined merus and ischium, and only a little longer than the palm ; the 

 dactylus is as long as the palm, and the palm is as broad (distally) as long. 



Consequently the left cheliped reaches beyond the middle of the palm 

 of the right, and the 2nd and 3rd legs surpass the large cheliped.

This genus, as Milne Edwards and Bouvier have remarked (Mem. Mus. 

 Comp, Zool., Harvard, I. c), might be united with Parapagurus, from which 

 it only differs in having the filaments of the gill-plumes either biserial, or 

 quadriserial with the outer row on either side of the shaft rudimentary. 



The species inhabit, not the abysses, but, for the most part, the moder- 

 ate depths (150-750 fathoms) of the sublittoral slopes, and have, at those
