 large, even in the female, and nearl}^ one-half longer than the cara- 

 pax ; they are everywhere spinulose above, except on the fingers of 

 the hand, which are smooth, curved, with their inner margins con- 

 tiguous, .inconspicuously denticulated. Ambulatory feet hairy, 

 somewhat irregularly and minutely spinulose above ; terminal joints 

 in the posterior three pairs short, not greatly curved. Dimensions : 

 Length of carapax, 0.36 ; breadth, 0.28 ; length of first pair of ambu-

 stituting more than one-fourth the length of the carapax, and very

 their length, and so closely pressed against each other that one is 

 usually crowded up over the other, as if twisted. External antennae
