in zoology, an insect of the order of vermes mollusca. The body of the aphrodita is oval, with many small tentacula or protuberances on each side, which serve as so many feet; the mouth is cylindrical, at one end of the body, and capable of being retracted, with two bristly tentacula. There are four species of this insect, viz. 1. The aculeata, with 22 tentacula, or feet, an inhabitant of the European seas. See Plate XXII, fig. 4. This figure is taken from the life. It was found on the shore of the frith of Forth, about a mile east from Leith, by Dr Letfom, and by him communicated to the proprietors of this work. Johnstone, Seba, and other authors, have given figures of the aphrodita; but they are not so accurate as could be wished. 2. The scabra, of an oblong shape, scabrous on the back, with about 20 tentacula. 3. The squamata, with 24 feet, and scaly on the back. 4. The imbricata, is very like the former, only its scales are more glabrous.
