COMPOSITE SNARES AND SECTORAL ORBS. 143 
spirals were carried around in loops, quite as represented; the hub was 
meshed and surrounded by a notched zone. A bit of cotton cord that 
clung to the handle had been utilized as a support for the foundation lines 
on one side (on the right of the cut), and within a scant series of cross- 
lines at the top a slight nest had been woven in which the little Zilla 
rested. Her feet clasped a trapline attached to the hub by a deltated

orbs made. 
My first opportunity to study Zilla in a natural site (uncolonized) hap- 
pened to be upon the grounds of Mr, F. M. Campbell, at Hoddesdon, Hartz, 
England. Later I noted the snares of great numbers of the genus in the 
highlands of Scotland, particularly in the neighborhood of Loch Achray 
and Loch Katrine. One especially interesting colony was_lo- 
cated at the sluices which regulate the flow of water from Loch 
Katrine. A footwalk crosses the stream, along which are short 
iron posts and an iron rail. Vast numbers of Zilla had settled along the 
cornices and panels of these posts, and from their nesting places had
