Numerous small species inhabit our fresh waters, among which should be distinguishedTrochetia, Dutrochet,—Which differ by having a bulge at the \ species (Geobdetla trochetii, Blainv.), is often seen upon the ground, pursuing the rvclopemcut of Hir 400 ANxN ELIDES. M. Moquin Tandon lias described a subgenus oy tbe name of Aulastoma, the mouth of whicli hasmerely longitudinal folds, several in number. In the suite of Nephelis, should be placed the BranchiobdelUa of M. Odier, remarkable for basingtwo jaws and no eyes. One species only is known, which lives upon the gills of the Crab. All these subdivisions have the anterior sucker a little separated from the body: the two next aredistinguished by a further separation, composing almost a segment, having a transverse aperture.
