"The black colouring on the front of this species varies in breadth from an almost imperceptible line, through bands of greater breadth, to a suffusion of the whole carapace and limbs with dark coloration, and no purpose would be served by keeping Dana's name nigrifrons. But the colouring of the legs will, I think, be found to fall into definite varieties. The walking legs, in short, may be either: Uniformly yellow. Uniformly dark brown. Yellow banded with dark brown across the middle of each joint. Yellow with a sharp black spot at the end of the meropodites and propodites. Yellow with narrow brown longitudinal stripes. An examination of a long sei-ies of specimens would probably give interesting results."
