Eyes large on rather IOML:. stout stalks ; in several specimens the 

 ri-ht eye is distinctly larger than the left (gee figures). Clieliped< 

 slender; tin- merus is nearly as long as the chela : the lim_rers gape 

 at base. ;:t least in the male, the thumb being enrve.l downward at 

 base rather abruptly ; outer edge of thumb linely -lent ieulate 

 beynd t he curve, e. Ige and tips..!' tinker fringed \vitli short hairs.

 but Mr. r>enedict, who has examined t he specimens, considers them 

 distinct. In the latter there are two pairs of spines behind the cer- 

 vical suture : tin- rostrum is longer and more slender : the ehelipeds 

 are longer, and the cliche hm-cr in proportion to meriis. Possibly 

 these ditl'erences may be due in part or wholly to immaturity .
