COMPOSITE SNARES AND SECTORAL ORBS.

It is certainly interesting to find these Orbweavers possessing in so 
marked a degree the spinning habit of the tribe most closely related to

that they both possess very de- 
cidedly the Epeiroid character- 
istics. 
In the meantime, there is 
another interesting peculiarity 
of ‘Triaranea’s web which 
needs to be noted, namely, the 
bell shaped den or tent of 
white silk hung amidst the 
maze (Fig. 131), and connect- 
ed with the trapline. A struct- 
ure of this kind, within which 
the spider constantly dwells, is 
not confined to this species. 
Many Orbweavers have a sim- 
ilar tent or some flossy uphol- 
stered crevice, hole, or leafy 
nest, within which they con- 
ceal themselves frequently or 
habitually. Triaranea often 
shows a remarkable addition 
to this ordinary bell shaped 
tent. There is an open and 
quite distinct tube attached to 
the mouth of the 
tent, from which it 
to the centre of the 
free radius is fasten 
runs through or along the floor
