the center is drawn tight by them, giving the appearance of a 
funnel-shaped opening to a tube. There is, however, no hole in the 
center of the web, and the cluster of threads may be flat or slightly 
depressed in the form of a gutter. 
Zilla montana. (Plate V, figure 4b.) 
This is a common house spider at Deer Island and at northern 
end of Moosehead Lake, Maine, making its nests like Z. atrica under 
the edges of clapboards. In North Carolina it lives on houses and 
in bushes at the summit of Roan Mountain, and in houses and barns 
at the base of the mountain, near the railroad.

In size and color this resembles the other species. The markings 
of the back of the abdomen resemble closely those of «-notata, but 
the middle of the back is usually lighter, and the two diverging 
dark marks near the anterior end are longer and narrower than in 
x-notata. The cephalothorax has a more distinct dark middle stripe 
than in the other species. In the males the palpi (fig. 4a) are twice 
as long as the cephalothorax, and about twice as long as those of 
x-notata. The front legs of the male are, however, one-eighth shorter 
than those of «-vofata, the front tibia and patella measuring a little 
less than twice the length of the cephalothorax. The form of the 
epigynum is shown in fig. 4b in comparison with those of «-/otata 
and montana. 
The webs are like those of other species with a large central 
spiral from which a strong thread extends to the nest. A large 
segment opposite this thread is usually left open, but is often partly 
or entirely closed. Adults are found from August until winter. 
First noticed by McCook at Annisquam, Mass., about 1885, and 
now found abundantly at Ipswich, Gloucester, Salem, and Lynn, 
where it lives in hedges and on the outside of houses, making 
tubular nests open at both ends under the edges of the clapboards. 
At Ipswich, I| first noticed them on a new cottage near the shore 
far from any other house, in 1900. At that time there were none 
of them on other cottages in the neighborhood or on the old farm- 
house at Lakeman’s beach. In 1904 they were on all the neigh- 
boring houses and barns and in the liliac bushes around them.
