Genus TAUROTRAGUS V^agner 1855 Type species. Taurotragus oryx (Pallas 1766). Generic diagnosis. Large tragelaphines. Compared with Tragelaphus the horn cores are tightly twisted and less openly spiralled, inserted wider apart, and with a strong anterior keel and some- times a posterolateral one. Large supraorbital pits; pronounced lateral flanges at the front of the nasals; median indentation at the back of the palate passing far forwards of the lateral ones; tooth rows set more anteriorly than in Tragelaphus; P4S with fused paraconid and metaconid (unfused in only 2 out of 27 Taurotragus oryx). Taurotragus arkelli L. S. B. Leakey 1965 1965 Taurotragus arkelli Leakey : 43, pis 43 and 44. Diagnosis. A species of Taurotragus differing from living T. oryx in having horn cores inserted less obliquely in side view, braincase top longer, cranium high and narrower, and the braincase top not depressed to produce a transverse crest across the top of the occipital. HoLOTYPE. Cranium with complete left and basal half of the right horn core, found in 1941. At present in the Nairobi collections. Horizon. The holotype was found on the surface of Bed IV, between LK and RK. Apart from this the eland is poorly represented at Olduvai. Remarks. The single cranium of T. arkelli is a little smaller than crania of the living eland and the horn cores are inserted less obliquely and perhaps clos
