To thesebelong all the various kinds of Toads, Water-frogs, Tree-froofs, etc. In the course of transformation these lose notonly the gills, but also the tail, which drops off in sometases earlier, in others later. In this respect the variousspecies differ somewhat from one another. In most FrogBatrachians the larv?e drop the tail very earl}^, and thetail-less frog-like form subsequently grows considerablylarger. Other species, on the contrary, as, for instance, thePseudesparadoxus of Brazil, as also an European Toad (Pelo-hatesfuscus) remain for a very long time in the fish form,and retain a lengthy tail till thoy have almost attainedtheir full size; hence, after their metamorphosis is com-pleted, they appear much
