THERIDIIDÆ.
The largest family of spiders. Most of them are small, with large rounded abdomens and slender legs. They live usually upside down, holding by their feet under their webs. They make large cobwebs of different shapes for different species, and depend for food on what is caught in them. To this group belongs the genus Erigone, containing a great number of the smallest spiders known. [Fig. 13] is the common house Theridion enlarged.
