New European fossil hominid material from an Acheulean site near Rome (Castel di Guido).

New fossil hominid material recovered from an Acheulean Italian archeological site is reported. It consists of two portions of femora, an occipital fragment, a fragmentary right maxilla, and a portion of parietal. Each specimen is described in detail and measurements are given. On the basis of the morphology, which includes primitive traits reminiscent of Homo erectus, and of the archeological, paleontological, and stratigraphical association, these new fossils are referred to the early European group.
