 dactylus. Postero-distal margin of merus of swimming leg unarmed. 



Color. — Male, (61208) surface of carapace mottled and speckled or 

 spotted with cream buff, olive buff, bice green or oil green + olive; upper 

 surface of hands and carpus same, upper surface of merus more tawny 

 olive, with tinge of gallatine yellow. Upper margin of hand in spots- 

 and middle third of carpal spine, and basal half of meral spines on 

 inner margin maroon + crimson. Teeth of fingers and distal half of 

 cutting edges and distal half of hairs on upper margin of movable 

 finger rich dahlia purple; inside of tip of upper finger and inside of 

 distal third of lower finger magenta shading into antwerp blue, on 

 proximal third of finger and inside of hand shading into primrose 

 yellow with tinging of olive buff. Hairs on proximal half of upper 

 margin of movable finger ochraceous. Hairs on upper anterior mar-
