its length. Tibia of palpus only one-third longer than broad, shorter than 
the tarsus ; tibial spur longer and sinuous; bulb with a long spiraloid 
spine, with two or three convolutions.. Protarsus i. black. Abdomen more

6. Palpi very long, longer than the carapace. Mandibles shorter and stouter, not 
compressed ; without teeth at the apex or on the anterior half or two-thirds ; 
with three teeth on each side of the fang-groove at the base, the anterior 
tooth on the upper margin the largest. Fang long, sinuous, but with a 
stout conical spur beneath at the base of the apical third section. Tibia of 
palpus four or five times longer than broad, twice as long as the tarsus ; 
tibial spur very short, sharp, and slightly curved; bulb globular, with a 
spine curving round its anterior circumference, but without spiraloid 
convolutions, Tarsus i. black. Abdomen very elongated, and constricted — 
in front of the middle ; carapace orange, with black cephalic area . . . championi, sp. n.

of white circular discs, situated within a diameter of each other and within 
a diameter of the genital rima, which is strongly emarginate in the middle. 
Between the two white discs are a pair of brown oval-clongate sacs, 
closely adjacent, dilate anteriorly, narrowed posteriorly, and encircling the

6. Colour as in the male, but much less pronounced. Vulva consisting of four 
brown circular discs; the anterior pair smaller, one-fourth of a diameter 
apart, two-thirds of a diameter from the posterior discs; the latter larger, 
one-half a diameter from the genital rima, which is not emarginate in the 
middle. Between the larger and smaller disc on each side lies a long 
oblique dark line, and behind the anterior discs a pair of dark curving 
lines—all of them indicating loops of the oviducts, which, with the discs, 
lie beneath the integument . . . . 2... 1. we ee ee Champion.

The males of this species are exceedingly variable, both in size and in the dimension 
and structure of the mandibles, no two examples being exactly alike. The tibial spur 
of the palpus also varies in shape.
