本文研究了日本比目鱼Paralichthys olivaceus（Temmink et Schlegel）的全缘羽状标本在幼鱼发育过程中的鳞化和栉鳞的形成过程，并与正常颜色的鱼进行了比较。具鳞的发育与正常鱼的眼侧和盲侧相似。在正常的鱼，形成的ctenii只发生在眼侧，而不是在盲侧。在完全环彩鱼类中，栉孔肌的形成发生在眼侧和盲侧，但在盲侧上的栉孔肌的形成在方式和图案方面与正常和完全环彩鱼类的在眼侧上的不同。在两栖鱼的盲侧，ctenii的形成不是像正常鱼那样从横轴进行，而是在ctenii的形成到达眼侧边缘后从背侧和腹侧边缘进行，这表明未知因素的扩散通过真皮组织。
The progression of squamation and the formation of ctenii in developing juveniles of completely ambicolorate specimens of the Japanese flounder, Paralichthys olivaceus (Temmink et Schlegel), have been examined and compared with those of normally colored fish. The squamation developed with a similar pattern on both the ocular and blind sides of completely ambicolorate fish and of normal fish. In the normal fish, formation of ctenii occurred only on the ocular side and not on the blind side. In the completely ambicolorate fish, the formation of ctenii occurred on both the ocular and the blind side, but the formation of ctenii on the blind side differed from that on the ocular side in both normal and completely ambicolorate fish in terms of both mode and pattern. On the blind side of ambicolorate fish, the formation of ctenii progressed not from the lateral axis as is the case in the normal fish, but from the dorsal and ventral edges just after the formation of ctenii reached the edges on the ocular side, suggesting the diffusion of an unknown factor(s) through the dermal tissue.
