There are two types of cell wall formation, They are: 1. centripetal constriction of the old cell wall, and 2. diflerentiation of a new cell wall from cytoplasm of each new cell.4, As amitosis needs less energy and takes less time than mitosis, it, therefore, facilitates not only the continuous differentiation of both epidermal and hypodermalscells, but also the development of secondary epidermis.

The general histological structure is fundamentally similar to that of the skin of frog (Pl. Ⅰ, Fig. 1). In the superficial layer of the dermis there are large and conspicuous round masses, which are akin to the sieve layer (Siebschicht of Kastschenko) both in appearance and in staining reaction (Pl. Ⅰ, Fig. 1; Pl. Ⅳ, Fig. 6). To our knowledge, the origin and function of these masses as well as the sieve layer are still obscure.According to the living habit, the life of the toad during the year can be divided into three seasons: namely, the hibernating, the breeding and the post-breeding season.In the hibernating season the epidermis reaches its maximal thickness due to increase in cell layer as well as in cell size. Cell division is rare in this season. The superficial layer is evenly cornified and the intensity of comification is intermediate, being stronger than that in the breeding season but less than that in the post-breeding season. This horny layer is connected intimately with the layer below and shows no sign of moulting (Pl.Ⅰ, Fig. 1; Pl. Ⅱ, Fig. 1). The flask-cells of Pfitzner (nucous cells of Legdig or goblet cells of Schultze) are very rare and when present, they are not fully differentiated from the ordinary epidermal cells. Melanophores are greatly expanded both in the epidermis and in the dermis (Pl.Ⅳ, Figs. 4, 3). Dermal papillae are tall and prominent (Pl. Ⅱ, Fig. 1).In the breeding season the epidermis is much thinner than that in the hibernating season. Moulting of skin goes on continuously. In association with moulting the flask-cells increase in number and show vigorous activity in secretion (Pl. Ⅱ, Fig, 2). Numerous amitoses are present in the middle and lower layer of the epidermis. At the initiation of the amitotic division a furrow appears at one side of the nucleus, which deepens and finally cuts the nucleus into two. Sometimes two furrows are formed, causing one nucleus to break up into three. A furrow may start at one end of the long diameter of the elliptical nucleus, causing it to split longitudinally into two daughter nuclei (Pl. Ⅰ, Fig, 2). We call this mode of amitosis furrowing amitosis. The usual mode of amitosis in which the nucleus divides by a central constriction could be found also, but cases are very rare. Mitotic figures are very rare. Melanophores are more or less contracted in the epidermis as well as in the dermis (Pl. Ⅱ, Fig. 2).In the post-breeding season the epidermis is intermediate in thickness between those of hibernating and breeding seasons. Due to the dryness on land the certification of the superficial layer is intense. Sometimes there are three layers of highly cornified cells, while in the other seasons this layer is always simple (Pl. Ⅱ, Figs. 3, 4, 5). Both mitosis and amitosis are present (Pl. Ⅱ, Figs. 6, 7). The former is much more in number than the latter. Wandering cells in the dermis penetrate into the epidermis and become epidermal cells (Pl. Ⅲ, Figs. 1, 2, 3). Flask-cells are fewer in number and less in activity than in the breeding season, hence the moulting of skin goes on slowly. All the melanophores are contracted in the form of a black spot (Pl. Ⅱ, Figs. 3, 4, 5). The blood vessels in the epidermis are greatly expanded, and are therefore easily seen (Pl.Ⅳ, Fig. 6).The nuclei of certain epidermal cells send out processes, which penetrate through the cell membrane and move along the intercellular spaces (Pl. Ⅲ, Figs. 4, 6). Sometimes these processes get into the neighboring cells (Pl. Ⅲ, Figs. 7, 8). In still other cases nuclei sued out coarse processes which come into contact with identical processes sent out by nuclei of neighboring cells (Pl. Ⅲ, Fig. 5). So far as we know, such intercellular activity of nuclei of the epidermal cells has not been heretofore repoifted. Its significance probably lies in the transportation of certain substances such as DNA. Nuclei showing this activity stain more intensively with Feulgen.The above description applies to the typical structures in each season. It is found that at the time between two se
