between the large middle eyes, as far as the dorsal eyes. 
In some specimens a white line comes off at a right angle on 
either side and goes to the dorsal eye, in others the upper surface 
is uniform in color. On the lower margin of the thorax, white 
bands pass back and are continued up over the back to the dorsal 
eyes, and more or less distinctly to the anterior lateral eyes. 
The sides of the head and the high clypeus are covered with 
short yellowish-white hairs; just below the front row of eyes a 
snow-white line runs across the clypeus giving the effect of a 
grin. The falces are pale, the palpi brown, with white hairs 
on the patella and a stripe of snow-white short hairs around 
the outside of the tarsus. Under parts pale, somtimes with 
some black spots. 
Abdomen black or brown, two white dots above spinnerets, 
two or three white chevrons in front of these and then two bands, 
which unite at the base; sides white. Legs, pale yellowish; first 
have fringes of yellowish-white hair; there is a dark stripe above 
on the femur, patella and tibia; tarsus, jet black. Some of the 
other legs have, in some specimens, dark bars or spots.

dotted with black,; patella and tibia with very long, white, and 
shorter dark fringe below, some of the white hairs being pedi¬ 
cellate. Metatarsus with white fringe, and both metatarsus and 
tarsus with black bands on a pale ground. Spines, tib. I 2-2; 
tib. II underneath, 2 serially behind and 2 anterior lateral, pat. 
II 1 anterior lateral and 1 posterior lateral, met. I 2-2, met. 
II 2-2 and 1 anterior lateral. It is unusual for Pellenes to 
have only two pairs under tib. I, and it may be that the third 
pair is broken off. The spinal armature varies somewhat in the 
individuals of a species. 
Our only specimen of tranquillus is so much rubbed that we
