. The animal kingdom, arranged after its organization, forming a natural history of animals, and an introduction to comparative anatomy. Zoology. Fitf. 203.—Eujilirosinc laureate. Eunice, Cuv.— Is likewise furnished with tuft-like gills, but the trunk is formidably armed with three pairs of differently-formed horny jaws; each of their feet has two cirrhi and a bundle of bristles; and there are five tentacles upon the head above the mouth and two on the neck. Some species only exhibit two small eyes. M. Savigny's family of Eunices is constituted by this division, and the particular genus is termed by him Leodice. A species, from one to four feet in length, inhabits the sea around the Antilles (, Cuv.), which is the largest Annelide known. Some upon our coasts are much smaller. M. Savigny distinguishes by the name of Marphisia certain species, otherwise very similar, which have no nuchal tentacles, and the upper cirrhus of which is very short, as Xereis sanguinea, Montagu. An allied species (N. tubicola, Mullur), inhabits a horny tube. After these genera with complex branchiae, are placed those in which the organs adverted to are reduced to simple lamina?, or even to slight tubercles, or which, lastly, are represented only by the cirrhi. Some of them resemble Eunice by the powerful armature of the trunk, and by their antenna; of unequal number. Such are Lycidice, Sav.,— Which, together with the jaws of Eunice, or even a greater number than in that genus, and often un- equal on the two sides, have but three tentacles, and cirrhi to perform the office of branchiae. Aglaura, Sav.— Have likewise numerous jaws, of an unequal number, seven, nine, &c.; but no tentacles, or which are entirely hidden ; and the gills are similarly reduced to cirrhi. Under this name 1 unite the Aglaura and CEnone of Savigny, and even certain species without tentacles, which MM. Audouin and Edwards leave in Lycidice, as and CE. lucida. The Nereids, properly so cal
