RESUMO
The morphology of the ophthalmic cornea in the blenniid fish Coryphoblennius galerita (Teleostei) shows adaptation to the amphibious life. Amphibious vision is provided by a flattened area within the cornea. Eyes of other, non-amphibious blenniids are compared with those of C. galerita.

In the course of a general investigation of the optic system in some trigger-fishes, a hypothalamic, ventricular channel-system with pores, leading to the outside of the brain, has been discovered in the inferior lobes of Rhinecanthus aculeatus (Balistidae). A description of the morphological relations of the channel-system to the blood-vessel-supply and the cranium suggests that the organ-systems involved form a functional unit. The possibility of a hormone-producing system is discussed in the light of physiological and ecological aspects.
