Cephalothorax blackish, pretty generally covered with short 
white hairs. The abdomen in this specimen has the hairs almost 
entirely rubbed off, only a few white ones remaining at the 
base. The integument is blackish, with pale chevrons and 
mottlings. Clypeus thickly covered with white hairs. Fakes 
brown. Legs and palpi, light brown, the first legs being a little 
darken than the others, with some light-colored and white hairs. 
Habitat : Arizona. 
Distinguished from nemoralis by the eyes of the first row, 
which in this species are all subtouching, and form a straight 
row, while in nemoralis they are separated and form a curved 
row.

Small spiders. The cephalothorax is rather high, not much 
longer than wide. Sides nearly parallel and vertical, highest at 
dorsal eyes from which point it slants in both directions. 
The cjuadrangle of eyes is one-fifth wider than long and is 
wider in front. The first row of eyes is a little curved, and the 
cephalic slant is so great that these eyes look down ; the middle 
are subtouching, the lateral are a little separated. All the eyes 
of this row are large, the lateral being four-fifths as large as 
the middle, the eyes of the second row are about halfway. The 
dorsal eyes are as large as the lateral, are as wide as the ceph- 
alothorax at that place, and stand out distinctly. The quadrangle 
occupies one-half of the cephalothorax. The thoracic plate slants 
slightly in its first half and thereafter abruptly. The abdomen 
is small ; the upper spinnerets are very long, almost equalling in 
length the abdomen. Legs, 4312, all slender. 
This genus is founded on a spider from South America, P. 
caiidata, and is named for our friend. Prof. E. B. Poulton of

Small spiders with spinnerets nearly as long as the abdomen.

The cephalothorax has the cephalic part covered with fawn- 
colored, and the thoracic with grayish-brown hairs. The abdo- 
men has grayish-brown hairs, which show reddish metallic reflec- 
tions when thoroughly dried. It is probable that the cephalo- 
thorax also had metallic coloring, in life. The upper spinnerets 
are covered with grayish-brown hairs except at the end, where 
they are enlarged and black. The legs are all yellow. The femur
