The genera are included in the family Tegenariidae (q.v.). (2) Sedentary Annelids, Tubicolous Annelids; a sub-order of Annelid a. They fabricate tubes either by gluing together particles of sand and shells, or by secreting a chitinous or calcified shelly substance, into which they can withdraw themselves by means of tufts or bristles in the sides of the body. Some live in mud or in holes in rocks, and others drag their tubes after them. Head indistinct, proboscis short, jaws not present; branches either absent or limited to three segments behind the head, except in the Lug-worm, where they are placed on the median segments. They are widely distributed, and are said to feed on vegetable matter. 2. Palæont .: The Tubicolous Annelids [1. (2)] are known from the Silurian onward.
