Summary

A rich collection of Ceratoserolis trilobitoides from the Antarctic Peninsula and the western and southern Weddell Sea is evaluated to describe the polymorphism and variations of the pigmentation. The species is very variable, though local populations show a relatively homogenous morphology. Transitional forms connect different morphotypes. Presumably the relative immobility of these animals, together with low fecundity and geographical or hydrographical barriers are responsible for the evolution of local races. C. cornuta and the “colour-spcies” of Cals (1977) are synonymized with C. trilobitoides.
