The sternum is rufous; the anterior thighs are separated by only 
the width of the lip at the base. 
The relative length of the legs is 4, 1, 2, 3; the first is much the 
stoutest. They are dark rufous in color, with blackish bars. 
The abdomen is golden yellow, with short hairs of the same color. 
There are four indented dots near the base, and posterior to these two 
indistinct dark bands extend to the apex. The sides are creased. The 
abdomen is distended with eggs in the only specimen which we have 
of this species. 
The venter is yellow, with three indistinct dark bands. 
The epigynmn presents a rounded plate with a large opening at the 
posterior edge. The internal parts are visible through the integument. 
Habitat. The only specimen which we have of this species is 
from the United States, but the exact locality is unknown. 
Observations. We have named this species for the well-known 
naturalist. Rev. Henry C. McCook, of Philadelphia.

The cephalothorax is high, especially so near the middle of the 
thoracic part; in front it inclines toward the face, and behind falls 
abruptly to the base. The thoracic is about one-fourth longer than the 
cephalic part. In color the cephalothorax is black, with the eye region 
covered with shortdark brown hairs, bordered in front and behind by a 
light yellowish edge. There are a very few short white hairs on the 
thorax. The fovea is rather deep, and is convex in front. 
The quadrangle of the eyes is wider than long, and not wider 
behind. The dorsal eye is a little larger than the lateral eye, and in a 
line with it. The small median eye is slightly nearer the dorsal than 
the lateral eye, and is on a line with their upper borders. The anterior 
eves are surrounded by white rings, those around the middle eyes being 
formed by long hairs. They are in an almost straight row, a straight 
line from the top of the middle eyes, cutting the upper borders of the 
lateral eyes. The middle are about twice the diameter of the lateral 
eyes, and are sub-touching. The lateral are separated from the middle 
eyes by nearly their own diameter. The lateral are placed further 
back on the face than the middle eyes. The clypeus is retreating, and
