ABSTRACT Many lower vertebrates exhibit colour change in response to the background. A dual hormonal control of colour change by two antagonistic pituitary melanophorotropic hormones was

first postulated in amphibia by Hogben and Slome1. It is well established that the melanotropins α- and β-MSH are responsible for pigment dispersion in the integumentary melanophore of lower

vertebrates and that these molecules are derived from a common precursor protein, proopiocortin, by specific processing within the intermediate lobe2. No evidence has been found for an

antagonistic hormone in amphibia, although the existence of such a molecule in the pituitary gland of teleost fishes has long been recognized and was termed the melanophore-concentrating

the salmon (_Oncorhynchus keta_) possessing an antagonistic function to MSH, and we describe here its chemical and biological characteristics. Access through your institution Buy or
