Various test features in six specimens of Echinocardium cordatum collected from South Africa, Trindade Island (South Atlantic), Australia, Japan and Ireland were compared with previously established data relating to British and New Zealand specimens. Morphological variations between the specimens were interpreted as infra‐specific differences and no evidence was detected that the spatangoid conventionally defined as E. cordatum is more than a single species throughout its extensive geographical range.
