1903.] A NEW SPIDER FROM CEYLON. 49 
with dirty yellow below, whitish with a black spot above ; femora 
jet-black variegated with paler patches above, in front, and 
behind, with a narrow whitish line between the tubercles below, 
the distal end yellowish white; patelle yellowish white, with 
two palely fuscous patches above and some behind; tibie and 
protarsi mostly jet-black, with a pale median inferior longitudinal 
stripe between the spines; tarsi pale above, black below; third leg 
with coxa and trochanter blackish below, the femur amber-yellow 
in its basal two-thirds, yellowish white with a black patch, much 
broader behind than in front, in its distal third; tibia black and 
whitish, the black predominating posteriorly; protarsus and tarsus 
mostly yellowish; fourth leg, with exception of its coxa, mostly 
yellowish white, lightly spotted above. Almost the whole of the 
upperside of the abdomen jet-black from its anterior margin 
backwards to the spinners, with the postero-lateral tubercles and 
the sides yellow; the under surface (i.e. the area between the 
lung-sacs on the epigastric region and behind the genital fold 
nearly back to the spinners) black, this black field showing a trans- 
versely oblong pale patch behind the genital aperture (Plate X. 
figs. 3 & 4). 
Carapace not strongly tubercular, flattish longitudinally along 
the middle line, with a shallow transverse depression behind the 
ocular area of the head; area between the ocular tubercles 
depressed ; eyes of posterior line (fig. 5) subequally spaced, the 
medians about 5 diameters apart, lying about their own diameter 
in front of a tangent joming the anterior borders of the laterals, 
which are distinctly larger than the medians; eyes of anterior line 
(fig. 6) strongly recurved, the inferior edges of the laterals as high 
as the superior edges of the medians, the latter considerably smaller 
than the laterals, about 24 diameters from each other and about 
2 diameters from the laterals'; distance between the medians 
about equal to the height of either above the edge of the clypeus, 
which is weakly tubercular and furnished with prominent angles, 
Mandibles prominent basally, scarcely tubercular ; margins of 
fang-groove thickly fringed, the posterior armed with one fang, the 
anterior with teeth, remote from base of fang; the posterior fringe 
continuous with a scanty band of hair passing up the inner side 
of the posterior surface of the mandible. 
Legs. Femur of Ist leg thickly covered in front with small 
tubercles, with a few large tubercles above and two rows of about 
five tubercles each below, the posterior surface smooth; tibia 
bowed, armed beneath with two rows of about 4-5 spines, the 
anterior and dorsal surface also spined ; protarsus a little longer 
than tibia, armed beneath on each side of the middle line with a 
band of longer and shorter irregularly arranged spines, those on 
1 Owing to a want of definition of the border of the corneal lens, the precise size 
of the eyes of the anterior line, and consequently of the width of the interspace 
between them, is hard to ascertain, varying apparently in different lights and with 
lenses of different power. In the above-given description the eyes are described as 
seen under a 4-inch objective and a platyscopie lens.
