Abstract
Eye extracts of Palaemonetes, Crangon, and other crustaceans were effective chromatophore contractors when injected into crustaceans and into certain fishes. Extracts from the eye stalks of Callinectes and of Palaemonetes were injected into the dorsal lymph sinuses of white-adapted and black-adapted tadpoles of Rana clamitans. In the case of white-adapted tadpoles there followed within 5 min. an expansion of melano-phores in the dorsal region of the trunk which reached a maximum in 13 min. Black-adapted tadpoles showed no melanophore response to the injection. This is additional evidence of the effect of an invertebrate hormone on a vertebrate system.
