Dr. Daniel Russouw Kannemeyer sent me a photograph of a dental plate in April, 1897, to which was appended the remark—“I conclude it to be Ceratodus, and its bones are said to be lying at Kraai Fontein. I have sent the man who found it to search for and fix the locality.” The search was not successful; and since then the rinderpest has prevented any attempt to reach, the locality, which is geologically at the top of the Karoo beds above the Coal of the Indwe district of Cape Colony, in strata which yield Zanclodont reptiles in other localities.
