 deep. Color of immovable fingers not covering proximal end. Legs 

 slender. Tip of male abdomen arcuate. 



Description. — Carapace very high in the middle, convex in both 

 directions. Lateral boundaries of cardiac and metagastric regions 

 deep, of ^rotogastric and mesogastric regions shallow. Surface 

 densely granulate, with a few raised lines of granules, which are not 

 prominent, namely, one long, transverse, on epibranchial region, one 

 transversely oblique, leading inward from the last lateral tooth, a 

 faint irregular, usually broken, protogastric line and a short epigastric 

 one. Front edge sinuous, a well formed, rounded lobule at outer 

 angle; lobes of middle pair with a slight indentation not far from 

 median hne; median notch small, continued by a closed fissure. 

 Inner orbital angle obtuse, margin between superior closed fissures 

 transverse, outer suborbital emargination broad and deep, the lower 

 margin of the orbit being advanced at this point in a small .tooth; 

 inner lower tooth bluntly rounded and set off by a V-shaped cut.
