Eight cranial and five postcranial fossil specimens are described and identified as remains of Odobenidae. Two of these (one, from Rhenen, certainly, and the other tentatively) are ascribed to the fossil, Early Pleistocene Odobenus huxleyi (Lankester, 1865), the others to the recent form, O. rosmarus (L.), while it appears possible to ascribe two of these even to the Adantic subspecies rosmarus. Some critical remarks are made regarding the systematic value of the genera Trichecodon and Alachtherium and the species antverpiensis (Rutten, 1907). The latter may eventually prove to be identical with huxleyi.
