Abstract

Retinofugal pathways of Polypterus senegalus C. have been examined by means of the radioautographic method. Contralaterally the retina projects to the hypothalamus, thalamus, pretectum and tectum. An important ipsilateral component has been observed. No retinal projection to the mesencephalic tegmentum has been identified. Comparing the primary optic system of Polypterus with that of other body Fish, indicates that this species possesses a combination of characteristics which are both actinopterygian and sarcopterygian. The significance of this mozaic arrangement is discussed.
