as wide as the cephalothorax. The falces are not quite, verti¬ 
cal. They are weak and rather long, with two teeth on the 
upper, and a hidentate ridge on the lower margin. The ster¬ 
num is oval, not truncated. The coxae are separated by less 
than the width of the labium which is longer than wide. The 
spines of the anterior legs are 3-3 on the tibia and 2-2, very 
long, on the metatarsus, besides laterals. The patellae are all 
spined on both sides. The posterior legs have numerous small 
spines and three circles on the metatarsi. The spinnerets are 
not visible from above, being short, with their insertion on the 
under surface. 
Our example is rubbed nearly hare. The eyes are on black 
spots. The cephalic part shows a few white hairs on a dark 
background. The thoracic part is brown, and seems to have 
had wide white bands on the sides. The abdomen is of a dull 
gray color with a few white hairs. The legs and falces are 
pale yellowish-brown.

fringed. 
The cephalothorax is high, vith the cephalic part very 
slightly inclined and the thoracic falling steeply in a rounded 
slope. It is nearly vertical and parallel in front, but grows 
narrower toward the end of the thoracic part. The eyes are 
on tubercles with depressions between. The quadrangle is a 
little wider behind than in front, is one-third wider than long 
and occupies nearly half of the cephalothorax. The front 
eyes are large and sub-touching and form a row which is 
curved downward. The middle are less than twice as large as 
the lateral. The second row is halfway between the others. 
The third row is as wide as the cephalothorax. The falces are 
stout, vertical, and convex in front. The upper margin has 
two teeth, one larger than the other, and the ridge on the lower 
margin is hidentate. The sternum is oval, very slightly trun¬ 
cated. The front coxae are separated by the width of the 
labium which is longer than wide. The tibia and metatarsus
