the anterior spinnerets. The calamistrum consists of seven or eight 
pairs of hairs about the diameter of the leg in length, Fig. 2c. The 
coxe of the fourth legs are more than their diameter apart, and the 
end of the sternum extends backward beyond them in a blunt point, 
Fig. 2d. The epigynum shows externally two round spermathece, 
each crossed by an opaque spot, and in some specimens spiral tubes 
can he seen connecting with them. The male palpi resemble those 
of Dictyna. The tube of the palpal organ coils around the edge 
of the tarsus, where it is supported by a wide thin appendage; it 
curves around the base of the tarsus to the upper end, where it is 
twisted and rests against a blunt process of the tibia. 
These little spiders live under leaves and are found by sifting in 
company with various Erigonez. They have been fond in various 
places around New Haven Connecticut and at Three mile Island, 
Lake Winnipesaukee, and Fitzwilliam, N. H. 
Amaurobius borealis, new. (Plate VIII, figures 3 to 3d.) 
Female 5 mm. and male 4 mm. long. The cephalothorax and 
legs are yellow brown, the legs darker toward the tips and the 
cephalothorax darker around the edges, but little toward the head. 
The abdomen is reddish brown with an indistinct pattern. The 
cribellum is small, not wider than the length of the first spinnerets 
and is indistinctly divided in the middle. It is on a slight elevation 
just back of the spiracle. The calamistrum occupies half the length 
of the metatarsus. The epigynum has a wide middle lobe, covered 
at the ends by the lateral lobes. The male palpus has the patella 
as wide as long, with one stout spine projecting over the tibia. The 
tibia is curved and has the usual complications shown in the figures. 
Fitzwilliam, N. H., abundant near the Rhododendrons. Portland, 
Me., under leaves on the ground. Mature in May; females with 
eggs in July.

Micaria laticeps, new. (Plate X, figures 4 to 4c.) 
One male of this species was found under a stone at New Haven, 
Conn. The length is 3 mm. The cephalothorax is a little higher 
than in the other species, and the head nearly as wide as the widest 
part of the thorax. The eyes of the upper row are at equal dis-
