other joints, covered with short white hairs and having a thin 
uneven fringe of brown hairs on the tibia of the first. 
One male. 
The spine on the falx distinguishes the males of protervus, 
curtus, dentichelis and born&ensis from fasciatus. 
Pancorius animosus sp. nov. 
This species has the cephalic plate red with a white centra] 
band. 
?. Length 8.5 mm. Legs 3412, first and second pairs a little 
the stoutest. 
The cephalothorax is rather high with the cephalic part 
plainly inclined forward. The thoracic part has a horse-shoe 
shaped part which falls a little from the dorsal eyes, and be¬ 
yond this the descent is steeper. The sides are parallel and 
nearly vertical, widening very slightly below the eyes and then 
curving inward, so that the lower margin of the cephalic and 
of the anterior thoracic part is not visible from above. The 
quadrangle of the eyes occupies two-fifths of the cephalothorax, 
is one-fourth wider than long and is very slightly wider in 
front than behind. The front eyes are rather large, close to¬ 
gether, in a row that is bent downward, the middle being less 
than twice as large as the lateral. The eyes of the second row 
are a little nearer the lateral than the dorsal eyes and are 
placed behind large black tubercles which rise between them 
and the lateral eyes. The third row is nearljy as wide as the 
cephalothorax. The sternum is longer than wide and is trun¬ 
cated in front. The front coxse are separated by the width 
of the labium, which is a very little longer than wide. The 
falces are vertical and stout with a single tooth on the lower 
margin, and two opposite, one larger than the other, on the 
upper margin. 
In the first and second legs the tibiae have 3-3 spines, and 
the metatarsi 2-2. Lateral spines are found on the tibiae but 
are lacking on the metatarsi. 
Our specimen is damaged. The cephalothorax is reddish- 
brown with a black band around the lower margin and black 
tubercles on the eye-region. The cephalic plate is covered with
