submedian tooth. The succeeding sinus is longitudinal. Outer 

 orbital tooth bifid, the inner branch very short, dentiform, the outer 

 branch long, slender, and curved, tip directed inward but not quite 

 reaching level of intermediate tooth. Hepatic spine slender, slightly 

 curved. The spines of the cheliped are as follows: A small sharp 

 spine near distal inner end of ischium; a curved spine at upper ex- 

 tremity of merus; two unequal spines placed obliquely-transversely 

 on distal half of carpus, the outer spine much the larger; a similar 

 spine near distal end of outer margin of manus and four irregular 

 spines on inner margin; about 13 small spines on prehensile edge of 

 immovable finger; a very small spine at proximal end of outer margin 

 of dactyl. Distal end of dactyls of first and second ambulatories 

 slender; inner edge of third dactyl very arcuate, outer edge distinctly 

 hollowed.
