Length of the female ;2; of an inch; length of the cephalo- 
thorax +, breadth 2,; breadth of the abdomen +. 
The cephalothorax is compressed before, rounded in front and 
on the sides, slightly convex, glossy, with a large indentation in 
the medial line of the posterior region ; it is of a yellowish-brown 
colour, with a red-brown band parallel to each lateral margin, 
and another in the medial line, whose greatly enlarged anterior 
extremity comprises the whole of the cephalic region. The 
falces are powerful, conical, vertical, very convex in front, glossy, 
armed with teeth on the inner surface, and have a red hue tinged 
with brown. The maxillz are straight, enlarged at the extremity, 
which is somewhat angular on the outer side, and of a brownish- 
red colour. The lip is-semicircular and prominent at the apex; 
and the sternum is heart-shaped, with prominences on the sides, 
opposite to the legs. These parts are of a dark-brown colour 
tinged with red, the apex of the former and the lateral margins 
of the latter having a yellowish-red hue. The legs are long, 
slender, provided with hairs, and of a brown colour, the base of 
the femora being the palest ; their relative length could not be 
ascertained, as they were detached and mutilated; but, judging 
from the relative size of the coxe, the first pair should be the 
longest, then the second, and the third pair the shortest. The 
palpi are long, slender, of a brownish-yellow hue, and have a 
slightly curved, minutely pectinated claw at their extremity. 
The eyes are seated on black spots on the anterior part of the 
cephalothorax; the four intermediate ones nearly form a square ; 
the two anterior ones, which are placed on a slight protuberance, 
are rather nearer to each other than the posterior ones, which 
are the largest of the eight; the eyes of each lateral pair are 
seated near to each other on a small tubercle, the posterior one 
being the smallest. The abdomen is subcylindrical, tapering 
somewhat to the extremity, which is obtuse, slightly curved 
upwards, and extends beyond the spimners; and there is an ob- 
tuse protuberance on each side of the anterior extremity, which 
projects over the base of the cephalothorax ; the upper part and 
sides have a silvery lustre, with a slight golden tinge, and on
