THE FEATHERFOOT SPIDER, ULOBORUS PLUMIPES. 173 Hentz observed the species on limestone rocks on the banks of Cyi»rus Creek, and in moist places in North Alabama. Its congener, U. mamme- atus, he found dwelling most frequently in cavities, among large logs, and in hollow trunks of trees.^ Emerton found Plumipes between loose stones or low buslies in New England. Mrs. Peckham almost invariably found this species building in dead branches, six out of seven being thus located.^ She gives an apt abstract of its habits. In form and color it resembles a scrap of bark; its body is truncated and diversified with small humps, Avhile its first legs are very uneven, bearing heavy fringes of hair on the tibia, and having the terminal joints slender. Its color is a soft wood

It has the habit of hanging motion- less in the web for hours at a time, swaying in the wind like an inani- mate object. The strands of its web are rough and inelastic, so that they are frequently broken, and this gives it the appearance of one of those dilapidated and deserted webs in which bits of windblown rubbish are fre((uently (Mitangled. Baron W'alckenaer says that the closely related European s))ecies, Ulo- borus Walckenacrius Duges, generally spins its horizontal snare between the stems of rushes in dry and warm places, which resembles that of Epeira in form, but of looser tissue.^ Ilahn found the species in the ' rhillyi-a iiiainineata.
