Third pereiopod possessing a semicircular-shaped posterior capsule on posterior edge both of coxal and basal segments. Fourth pereiopod possessing a projected peg on top of basal segment.The first maxillipeds of three different stages of the larvae in metamorphosis are described. By basing upon the fact shown in the metamorphosis of the first maxilliped of the larval stages, the genus Huargulus seems to be one of the larval stages of the genus Argulus. So the genus Huargulus becomes invalid.This new species was secured from, the lateral line, the surface of abdomen, the gills, and the mucous membrane of the oral cavity of the yellow-barbeled catfish. The last-named location of the parasite is for the first time recorded.

The present paper embodies a comprehensive investigation of all tissues of the tadpole tail of Kaloula borealis and their degeneration during metamorphosis. The following are the important findings.The structural characteristics of the tailThe tadpole tail of Anura is a temporary organ functioning in its embryonic aquatic life. In this ephemeral organ a number of primitive characters are retained. For example, the epidermis consists of only two layers of cells. A cuticula is present on the superficial layer. Its cells can multiply by division. The dermis is extremely thin and consists of fibers only. Muscles exist in the form of myotomes,in which many young myofibers are retained. The connective tissue matrix is not completely differentiated and looks similar to the mesenchyme. These primitive conditions are also present in the trunk portion of the young tadpole, but at a later stage the above mentioned structures gradually assume aspects obtaining in the young frog. The tail however, retains these primitive conditions unaltered to the very end. In the metamorphosis it undergoes regressive degeneration.Maintenance of unity by the tail in degenerationIn the course of degeneration, activities are concerted. An axial gradient is manifest. Degeneration activity is most pronounced at the tip of the tail, less in the middle portion and least at the base. As a result, the tip quickly vanished, the other parts follow in an orderly sequence. Finally the whole organ disappears.The rate of degeneration of various tissues also varies. Epidermis and notochord lag behind. In order to accommondate themselves in the shrinking space the epidermal cells pile on top of each other, and the epidermis thus becomes multilayered and the notochord becomes undulated. The modifications are in accord with the role these tissues play.The general rule of the degeneration of the tail tissueIn a given tissue, elements that are advanced in differentiation also lead in degeneration. E. g. muscle fiber in myqtome, vacuolar cell in notochord, ganglion cell in spinal ganglion. The less differentiated elements lag behind, e. g. endomysium, noto-chordal epithelium and amphicyte.In degeneration, all fibral tissues including connective tissue-, nerve- and muscle fibers, become swollen and losening up, and gradually become dissolved. Cytoplasm of all cells lose their tight and compact nature and takes deeper stain with eosin. Hereafter vacuoles and pigment granules often appear in it. Unless compressed, the nuclei keep their shape but lose their contents. Degenerating epidermal cells of superficial layer undergo keratinization and finally are cast off. Cells of basal layer first fragment and then vanish.The nucleoli show greater persistence. This is especially pronounced in the nucleoli of ganglion cells and muscle fibers.Pigment granules are slow to disintegrate. They frequently collect in masses, and the tail become black during metamorphosis.Mitosis and amitosisAmitosis occurs in both layers of the epidermal cells, in the nuclei of muscle fibers and in the large cells of the connective tissue matrix. In the formative period of muscle fibers, multiplication of nuclei is soly by means of mitosis. At the end of differentiation mitosis ceases. Hereafter multiplication of nuclei is soly by means of amitosis. In their upgrade development, epidermal cells and the large cells of connective tissue matrix too, cells multiply by means of mitosis. But at the completion of differentiation amitosis makes its appearance and goes on side by side until metamorphosis.Before beginning of metamorphosis, all kinds of the cells in the tail tissue cease to multiply. Only the cells of ependyma and wandering cells of the connective tissue matrix mitosis goes on as usual during degeneration.The significance of mitosis and amitosis is discussed.Degeneration and developmentIn the development of the embryo, there is growth and differentiation of cells and tissues, but coupled with it, there is senescence and death. These two phases of life contradict and yet complement each other. This i
