• Surface relaxation and contraction waves were examined in still pictures of eggs of the newt, Cynops pyrrhogaster. The waves were clearly observed during changes in surface pigmentation and in egg contour, induced by changing the egg shape into a cylindrical form within a narrow trough of agar. On the surface of the animal half which contained abundant pigment granules, the pigmentation became dark at the animal pole region and slightly brighter around the dark area, shortly before the first cleavage. The cleavage furrow always appeared at about the center of the dark area, ordinarily in the direction of the short axis in the cylindrically elongated egg. Simultaneously with furrowing, the bright and dark regions were cut apart by the furrow, resulting in separation into two sets of the bright and dark bands, on the sides of the furrow. With progression of the cleavage, each set of the two bands shifted horizontally in the direction away from the furrow plane. The bright and dark regions were observed as a slightly swollen ring and a constricted ring, respectively. On the pale surface of the vegetal half containing no pigments, both waves could be also detected as a bright-swollen band and a slightly dark-constricted band.
