| 内容記述 | 1. The early development of Tethya serica Lebwohl was described. 2. This species belongs to the dioecious type and the fertilization takes place ectosomatic. 3. Eggs, usually spherical in shape, have a diameter of 0.17-0.18mm. They are densely laden with yolk and are covered by a clear vitelline membrane, through which are radiated a number of fine processes, rather stiff and not movable. Their length is measured with an ordinary microscope as the same as that of the egg-diameter, but their tip can be traced until about twice the length of the egg-diameter when observed with a phase contrast microscope. 4. When fertilized, the fertilization membrane is elevated and the egg comes to adhere to the substratum. Almost simultaneously with this, each process gradually begins to bend over the surface of the egg and is finally enclosed within the perivitelline space, making layers around the egg. 5. Eggs segment totally and adequally. But there are many variations in cleavage patterns, which probably owes to the degree to which the egg comes to adhere to the substratum. | |||||
