spinule below. Major hand in 



Description. — Carapace suboval, convex in an antero-posterior 

 direction, nearly flat in a transverse direction; anterior half rough 

 with squamose granules; regions distinct. Front convex, having two 

 lobes with granulate margins separated by a V-shaped sinus; outer 

 angle of each lobe subrectangular. Second normal antero-lateral 

 tooth of this genus suppressed, being completely united with the orbital 

 tooth which is not prominent; 

 three remaining teeth sharp- 

 pointed, posterior one smallest. 

 Outer fissure of orbit broad, V- 

 shaped. 



Chelipeds heavy, very unequal, 

 arm spinulous on upper edge; 

 wrist covered with beadlike tuber- 

 cles and with a deep anterior 

 groove and an inner right angle 

 tipped with a spinule; a second 

 male with upper and about two-thirds of outer surface ornamented 

 with bead tubercles; lower third and distal extremity smooth and 

 shining; fingers broad, not gaping, brown with fight tips; dactylus 

 with large basal tooth; color of immovable finger not running

 outer surface of the major as well as the minor palm tuberculate.
