These originate in the immediate vicinity of the parietal crest and run rostrolaterally towards the orbit. Lateral crests com- posed of 4 enlarged, prominent pointed scales, extending to the supraorbital crest (11 pointed scales) and to canthi rostrales (5 scales). Body rather stout. Dorsal crest well developed, composed of scales in groups of three anteriorly and four posterior- ly. Increasing posteriorly in size within the group, giving the back a serrate appearance. Dorsal crest extends to the tail and becomes indistinct within its terminal third. The first scales of the series of three just behind the head are longest, reaching mm length. Ventral crest moder- ate to weak, best developed on the throat; posteriorly scales are shorter but still visible up to posterior belly. Scalation heterogeneous. Sides of body, tail and upper sur- faces of limbs covered with irregularly sized, convex, small scales interspersed with larger convex scales. Lar- gest of these form a narrow row running from neck just behind temporal crests to tail. A second row of slightly smaller scales runs from shoulder to hind leg. This row is much less distinct and more irregular. Vent, inner side. Fig. 4. Trioceros hanangensis n. sp. (subadult male, ZFMK Fig. 5. Trioceros stemfeldi (male) Ngorongoro Crater. 82368) from Mt.
