outer side of the tibia, and four on the inner side, and three pairs 
of spines on the metatarsus. In females these spines are long, more 
than half the length of the tibia; in males they are short like the 
spines of the other legs. The abdomen is oval, not much longer 
than wide, resembling in shape as well as in markings that of 
Amaurobius sylvestris. The lower spinnerets are wide apart, and 
there is a wide opening to the trachez between and in front. The 
edge of the tracheal opening is thickened and colored on the inner 
side so that it resembles a small cribellum. 
The colors are translucent white and gray. The legs are marked 
with broken dark rings at the ends and middle of the joints. The 
cephalothorax has a narrow black edge and broken radiating dark 
marks like Ca@lotes medicinalis. The abdomen is marked with a 
series of oblique light spots in pairs like Amaurobius. On the under 
side the abdomen is light in the middle; the cox are light, and 
the sternum is light in the middle and dark at the sides. The light 
color turns yellow by long keeping in alcohol. 
The male palpi have two processes on the tibia—one on the 
upper side turned outward and sharp pointed, the other on the 
outer side about half as long, stout, and directed forward. The 
palpal organ is large, extending backward beyond the base of the 
tarsus. The tube begins at the hinder end, extends around the 
inner side and ends in the groove of a thick process on the 
outer side.

A single female from Clarendon Hills maple swamp is 3 mm. 
long, three-fourths the size of agi/is. The proportions of the body, 
the eye arrangement and the shape of the sternum and maxille are 
the same as in agilis. The opening of the trachea is midway 
between the epigynum and spinnerets, not as far forward as in 
agilis. The spinnerets are in a line, with the lateral pair slightly 
larger than the others as in agz/is, but the spinnerets are closer 
together, the middle pair almost touching. The lateral spinnerets 
are shorter than in agi/is, being a third the length of the abdomen, 
while in agilis they are half as long as the abdomen. The epigy- 
num is shaped much as in agi/is, but on each side there is a brown 
loop under the skin that does not show in agilis. The color is 
light brown, the legs without rings or markings. The cephalo-
