Abstract

THE study of the newly discovered recent member of the Cambro-Silurian mollusc group Monoplacophora has caused me to extend investigations also to animals other than molluscs of the early Cambrian fauna. Then, I was struck by the appearance of some Olenellid Trilobites figured by Walcott1, showing additional segments behind what usually forms the long spine of the last segment (Fig. 1).
