The egg membrane is smooth with a wide perivitelline space. The size is about 3.16 mm, and there are about 39 pieces of oil globules. (B) The pigmentation is absent in the embryo. The yolk is segmented (Mito, 1961). Under scanning electron microscope: (C) The pores are slightly raised on the surface of the egg membrane, and the pore canal is completely closed. Protruding plugs are seen in the center of the canal. The numbers of the pores are about 17pieces/100£g¢T. (D) Many accessory openings are found around the micropyle region, and there are no plugs in the center. The accessory openings are arranged regularly in the radial ridge around the micropyle. (E) The micropyle is in a funnel shaped, and the micropyle canal is smooth. The bottom of the canal has a lip-ring. The size of the micropyle is about 17.5£gm.
