Animal Colour Changes and their Neurohumours

Abstract

THIS is a very valuable compilation of literature A on chromatic function which, together with previous reviews by Fuchs (1910) and Hogben (1924), makes readily accessible all references on the subject from antiquity to recent times. The introductory chapter deals with distribution and types of chromato-phores, with their activities and methods of measuring them. This is followed by a systematic survey of chromatic response in cephalopods, Crustacea and cold-blooded vertebrates ; seasonal coat changes in birds and mammals are not discussed. The final chapters consider development, genetics and ‘special activities' of vertebrate chromatophores. The bibliography of more than 1,200 titles is conveniently arranged under three heads, namely, surveys, publications (chiefly historical) before 1910, and a complete list from 1910 to 1943 inclusive. As we have learned to expect from Prof. Parker, the script is lucidly and persuasively written.
