The skuU is much narrower than in either T. ferruginea, T. belangeri, or T. cUnensis, and is slightly smaller than the skull of the last-mentioned species. Its most striking peculiarities are the depressed character of the snout, which arches downwards, and the regularly tapering form of the same part, the absence of a constriction between the orbits or concavity in the upper margin of the orbit, which is straight and continuous with the lateral margin of the snout. The nasals are proportionately broader than in the foregoing species, and very little expanded pos- teriorly. The supra-orbital foramen is distinctly removed from the orbital ma
