This paper deals with a morphological and histological description of the following teratic abnormities found in Acheilognathine species and hybrids.
1. Tetrophthalmia in a larval hybrid between Rhodeus spinalis ?? from Taiwan and Rhodeus ocellatus ?? from Japan. It represents a case of duplicitas anterior.
2. Duplication of dorsal fin in a hybrid between Acheilognathus rhombea ?? and Acheilognathus tabira ??, both from Japan, representing a case of duplicitas media asymmetrica.
3. Lordosis in a hybrid between A. rhombea ?? and A. tabira ??, accompanied by edema in the hind brain region.
4. Scoliosis in a larval hybrid between A. rhombea ?? and A. tabira ?? .
5. Suppression of organ differentiation and larval development as a result of an excessive bulk of yolk in a larval hybrid between A. rhombea ?? from Japan and R. ocellatus ?? from Korea.
