PILUMNIDAE. 40 



Chlorodopsis venusta, sp. nov. 

 PL 1, Fig. 5. 



Carapace with a few, rather long, scattered hairs; legs with similar 

 but more numerous hairs, not concealing the sculpture ; chelipeds almost 

 naked. 



Posterior third of carapace not areolated. Anterior § divided by smooth 

 grooves into regions and sub-regions, which are covered with very numer- 

 ous sharp granules ; these granules become much finer on the posterior 

 third. 



Front cut into two rounded denticulate lobes, and outside of each a 

 narrow acute tooth. The two upper fissures of the orbit are faintly 

 marked. 



The antero-lateral margin has besides the small orbital angle, four teeth, 

 the last three of which are similar, curved, spiniforin. Tooth E of Dana 

 is thick, acute, and fused with the adjacent area 1 L ; tooth N bears a few 

 denticles on its sides. 2 L, 3 L, and 4 L are distinct ; 5 L and 6 L are only 

 partially separated from each other. 1 L, 3 L, 4 L, and 1 R, the submarginal 

 areas, are high and rough with granules, but not spined. There is a 

 sharp subhepatic denticle. While the outer angle of the basal antennal 

 joint is prolonged into the orbital hiatus, the movable part of the antenna 

 is not excluded from the orbit. 



Chelipeds unequal. Arm irregularly spined on anterior margin, sharply 

 rough above, finely granulate outside. Wrist coarsely and sharply granulate, 

 two spines at inner angle. Hands covered with crowded granules, which are 

 finer below and on the inside. Fingers gaping, three teeth on prehensile 

 edge of each, dactyl us with denticles outside towards the base. 



Legs spinulous above. 



Color in spirit mottled, variable, the dark part sometimes forming a vari- 

 able but bisymmetrical band from front to back. Legs with a few transverse 

 dark stripes. Fingers brown or black with light tips.
