Peckham—The Aitidae of Borneo. Oil 
of the first leg are fringed. With the exception of the tarsi, 
all the joints of all the legs are spined. In the first and second 
the tibiae have 3-3 and the metatarsi 2-2 besides laterals. In 
the third and fourth the metatarsi have two circles. 
The cephalothorax is of a dark reddish-brown color, while the 
abdomen is much lighter and yellowish. The cephalic part is 
covered with golden hairs, the color deepening to red around the 
eyes. The sides have wide white bands which pass around the 
lower thoracic part. The abdomen, judging from the marks 
that are left on our specimens, is covered to the ends of the 
spinnerets with a mixture of white and reddish-golden hairs, 
and has two impressed white dots. The falces are dark brown 
with some long white hairs. The clypeus is very low. The 
palpus is reddish-brown with two longitudinal white lines run¬ 
ning as far as the tarsus. The first leg is brown, the patella 
being light-colored, while the tibia and metatarsus are darkened 
and have a heavy, stiff, black fringe. There are some short red 
and white hairs on the upper surface, and the under side of 
the femur has a dark streak. The other legs are light brown. 
The mouth parts are dark brown tipped with white. The 
sternum is yellow with a few white hairs, while the coxse are 
much darker and are marked by a sooty black streak which 
extends, in some cases, on to the trochanters and femora. 
Three males, from Sarawak. 
Malleus gen. nov. 
The cephalothorax slants steeply in both directions from the 
dorsal eyes, the thoracic part falling still more abruptly after 
the first half. It rounds out widely at the posterior part, the 
sides being vertical and parallel in front. The quadrangle oc¬ 
cupies two-fifths of the cephalothorax, is a little wider in front 
than behind, and is nearly one-fourth wider than long. 
The front eyes are close together in a straight row, the lat¬ 
eral being more than half as large as the middle. These eyes 
bulge out on the sides so that the first row is wider than the 
cephalothorax at that place. The second row is halfway be¬ 
tween the others, and the third is as wide as the cephalothorax.
