that, while two correspond with my type, the third (obviously 
the female), a rather darker specimen, differs in having the 
two claws of the foot more equal (a difference found also 
between the sexes of Adorodocia strigata), while the larger 
claw is very slightly and equally divided at the tip. The 
front claws are lost, but I think it may be assumed that in 
claw-structure the female P. enigma is exactly similar to the 
female A. strigata.
