then suddenly contracting and again expanding on the first two 
abdominal segments ; suddenly contracting on the third and running 
as a broad stripe to posterior extremity. Scattered over the dorsum 
of the cephalothorax are numerous tubercles, having whitish bases 
and black tips, and generally having also a black spinose hair arising 
on one side of the tubercle near the apex of the white portion, and 
extending beyond the tip of the tubercle; a transverse row of similar 
tubercles on each abdominal segment. Dorsum of abdomen covered 
with numerous small black granules. Eye eminence gray, well devel- 
oped, canaliculate, each carina surmounted by a well-marked series 
of tubercles, whitish with black tips. Chelicerz large, light brown, 
with tips of claws black; first joint long, cylindrical, convex, fur- 
nished above with black spinose tubercles ; second joint very large, 
smooth, except for some black spinose hairs, articulated at a right 
angle with the first, prolonged above in the form of a large conical 
horn, curved forward. Palpi slender, very long (three times as long 
as body), smooth, except for rows of stiff black hairs ; light brown, 
except middle portion of femur, which is black. Ventrum, including 
cox, grayish white, with numerous black hairs. Trochanters light 
brown, almost whitish, with a few tubercles. Rest of legs brown, 
with femora darker; proximal joints with rows of spinose tubercles. 
Female.—Body 7.5 mm. long; 4.5 mm. wide. Palpi 6.5 mm. long. 
Legs: I. 21 mm.; II. 36 mm. ; III. 23 mm. ; IV. 32 mm. 
Dorsum light mottled gray, with a rather distinct darker central 
marking beginning at anterior border of abdomen, and expanding 
rapidly on the first two segments; suddenly contracting on the third 
segment and running as a stripe to the posterior extremity. Scat- 
tered over the dorsum of the cephalothorax are numerous tubercles, 
having whitish bases and black tips, and generally having also a black 
spinose hair arising on one side of the tubercle near the apex of the 
white portion, and extending beyond the tip of the tubercle. A trans- 
verse row of similar tubercles on each abdominal segment. Dorsum 
of abdomen having numerous small black granules. Eye eminence 
well developed, gray, canaliculate, each carina surmounted by a well- 
marked series of tubercles like those on the dorsum. Chelicerz light 
brown, dorsal proximal portion of first joint mottled with chocolate 
brown ; tips of claws and a blunt tubercle at base of outer claw, black ; 
both joints furnished with scattered black, spinose hairs. Palpi rather 
long (but very much shorter than in male), slender; very light brown, 
almost whitish, with middle of femur black; all the joints furnishee 
with well-developed spinose hairs, those on the tarsus being more
