One of the problems dealing with the migration of Quaternary Bovid stocks from Eurasia to North America via the Bering Straits, is the extreme fragmentary nature of the fossil record. A number of the dozen or so genera now recognized have been established on the basis of single fragmentary specimens. Many times these consist of isolated bone fragments such as horncores, partial crania, dentitions and even less diagnostic elements of the axial skeleton. As recently as 193 7 species of two genera mw to the North American continent were identified from Alaskan deposits on the basis of similar fragmentary remains ( l) . It is with considerable interest, therefore, that the occurrence of a member of the goat group (genus Capra), previously unknown to the American scene, is described from the Quaternary of Iowa. The specimen in question, represented by a partial cranium with horncores, appears to be that of a fossil Ibex.
