Note préliminaire sur les restes de siréniens recueillis en Belgique.
Zool. Anz. 12(304): 197-200. Apr. 1, 1889.
–Recognizes two forms from the Belgian Rupelian (Oligocene): Metaxytherium Guettardi and Halitherium Schinzi. States that one (presumably the former) is ancestral to Halicore, the other to Manatus. Crassitherium is also present and, if a valid taxon, would constitute a third member of the fauna, ancestral to Rhytina. Manatherium is considered of doubtful validity and more probably equivalent to M. Guettardi. The two Rupelian species definitely recognized are said to have complete epiphyses on the centra of all vertebrae.
