Abstract
Retinofugal pathways of P. senegalus were examined by radioautography. The retina projects contralaterally to the hypothalamus, thalamus, pretectum and tectum. An important ipsilateral component was observed. No retinal projection to the mesencephalic tegmentum was identified. Comparing the primary optic system of Polypterus with other bony fish, revealed this species possesses a combination of characteristics which are actinopterygian and sarcopterygian. The significance of this mozaic arrangement is discussed.
