The cephalothorax is high, and is dilated behind the dorsal 
eyes. The cephalic part is separated from the thoracic, and 
occupies of the cephalothorax; it is nearly plane, slightly 
inclined forward, and is widely rounded on the sides. The 
thoracic part is convex, and a little contracted behind. It falls 
from the dorsal eyes. 
The quadrangle of the eyes is wider than long, and is a 
very little wider behind than in front. The anterior eyes are in 
a curved row; they are all small, the middle being a little less 
than twice as large as the lateral, and are placed on a ridge; the 
middle eyes are a little separated, and the lateral are separated 
from them by }/± their own diameter, and are much further 
back. The eyes of the second row are a little nearer the lateral 
than the dorsal eyes. The dorsal are a little smaller than the 
lateral eyes; they arc on the margin of the cephalothorax, and 
are further from each other than from the lateral borders. The 
clypeus is a little less than *3^ as high as the anterior middle 
eyes, and is vertical. 
The falces are as wide as the first row of eyes, and are as 
wide at the base as long, bulging out in front, tw^ce as long as 
face, diverging a little at the extremity, and inclined forward. 
There is a short tooth on the inner anterior edge of each falx. 
The fang is about as long as the falx. 
The maxillae are long; they are rounded, and a little enlarged 
at the extremity. The labium is a little more than 3 / 2 as long 
as the maxillae, )/> longer than wide, a little contracted, and 
blunt at the tip. 
The sternum is narrow, truncated in front and rounded be¬ 
hind. It projects between the anterior coxae, which are sepa¬ 
rated by the width of the labium, and are stout and long. 
The relative length of the legs is 1, 4, 2, 3; the first pair is 
much the stoutest. There are femoral, patellary, tibial and 
metatarsal spines on the four pairs, those on the metatarsi of the 
fourth extending to the base. 
Coloration. The cephalothorax is dark brown with a few 
white hairs on the middle portion, and a wide white band on 
each upper side, which includes the small median and the dor-
