In March of the present year (1909) the Rev. R. Ashington Bullen, who was then travelling in Majorca, wrote to inform me of the existence of a supposed ossiferous breccia situated on the east coast of that island. This caused a long-deferred project of exploring the Balearic Islands in search of Pleistocene cave-deposits to be carried out, and a month was spent in this manner, although a much longer period would be required for an exhaustive examination of Majorca alone, which was the only one of the group visited. A considerable tract of limestone country was investigated, and the result was the discovery of three ossiferous cave-deposits, including the one mentioned above. Similar remains were procured from each of these, and on examination prove to be those of an ungulate which appears to be without parallel. No great quantity of material was obtained, but this fortunately includes a well-preserved skull of an old individual with the associated mandible and atlas vertebra—the typespecimen, see Fig. 1—as well as a number of perfect examples of various limb-bones.
