BRACHYTHELE KEITHI, sp. nov. 
Plate 7, fig. 11. 
Integument of cephalothorax and legs light chestnut-brown; that 
of the chelicerae dark chestnut; integument of abdomen and spin- 
nerets clear brown. Pubescence of carapace brown of golden lustre; 
that of abdomen dense, of similar golden brown color or of more 
coppery lustre. 
Eye-tubercle strongly convexly elevated between the posterior 
median eyes. Eye-area twice as wide as long (45:22); anterior row 
a little shorter than the posterior (45:42). Anterior row a little 
procurved. Anterior median eyes a little more than their radius 
apart, closer to the lateral eyes; diameter but little more than two 
thirds the longer diameter of the lateral eyes (ratio near 23:31). 
Posterior lateral eyes slightly longer than the anterior (33:31). Pos- 
terior median eyes elongate, narrowed caudad, length to width 
about as 3:5 — smaller than lateral eyes (lengths as 25:33), nearer to 
these than to anterior medians. A line tangent to caudal edges of 
posterior eyes on each side in type passing through anterior third of 
opposite anterior median eye, (Plate 7, fig. 11). 
Labium clearly wider than long; distal margin mesally incurved. 
Spinules none. 
Spinules on proximal corner of endites short and stout, constricted 
near or a little above base, distally expanded and rounded. 
Thoracic fovea recurved. 
Sternum longer than wide; gently convex. The sigillae at level 
between second and third legs most distinct, marginal. Sternum 
with numerous fine tubercles from each of which arises a hair. 
Paired claws with teeth in two rows; teeth of each row mostly 
seven or eight in number. Unpaired claw smooth. ‘Tarsal scopulae 
dense, extending to base; none divided by a setose line or band. 
Spines long and moderately stout, black. 
Posterior spinnerets more than two thirds as long as the abdomen 
ventrally; the three joints subequal in length, decreasing in diameter 
distad, the second being more slender than the first and the third 
than the second. Anterior spinnerets twice or more their diameter 
apart at base. 
Female. Length, 30 mm. Length of cephalothorax, 14 mm.; 
width, 12 mm.
