Two members of the Rhodesia National Parks Department make a preliminary reassessment of the status of the black rhinoceros Diceros bicomis in Rhodesia, and examine the techniques for estimating numbers used by Dr. H. H. Roth in his paper on White and Black Rhinoceros in Rhodesia, in ORYX, December 1967 and which, they believe, led him to overestimate the situation. They call the black rhino the hook-lipped rhino, but the more usual name has been retained in the title as being more widely understood.
