The first group in-cludes those that habi-tually live attached bythe foot, which is pro-longed into a pedicle;and it includes two fa-milies, the Flosculariansand the Melicertians,both of which bear acertain general resem-blance to the Vorticel-lince (§268) on the onehand, and to Zoophytes(Chap. XI.) on the they are commonlyfound attached to thestems and leaves ofaquatic plants, by a longpedicle or foot-stalk,which bears a somewhatbell-shaped body; and inone of the most beautiful Stephanoceros Mchornii. spCcieS, the StephanO-. KOTIPERA:—FLOSCrLARIA^^S AXD IIELICEETIAXS. 499 ceros Eichornii (Kg. 202), this body has five long tentacles,beset with tufts of short bristly cilia, reniiiiding us of theciliated tentacles of the Bryozoa (Chap, xiii.), T^^hilst thebody seems to be enclosed in a cylindrical cell, resemblingthat of Hydrozoa and Bryozoa. A comparison of this ^vithother forms, however, shows that these tentacles are onlyextensions of the ciliated lobes which are common to all themembers of these families; and the so-called cell is notformed by a thickening and separation of the outer tegument,but by a gelatinous secretion from it; so that, as the rest of theorganisation is essentially confonnable to the Rotiferous type, nosuch passage is really established by this animal towards othergroups, as it is commonly supposed to form. In one respect,Floscularia is still more aberrant; for the long bristly fila-ments with which its lobes are beset, are not capable ofrhythmical v
