Fig. 3: Detail of the head of the adult male holotype of Chamaeleo (Trioceros) conirostratum n. sp. from Lomoriti, Imatong mountains, southern Sudan. are distinct, comprising 4 enlarged tubercles on each side. The canthal ridges are edged in enlarged, but smooth oval scales (5 on the left and 6 on the right). The canthal ridges merge anteriorly to end in the base of an elongated non-annulated thin cone projecting 3 mm off the front of the upper lip. The base of the cone appears to be pliable (In the preserved specimen this appendage is bent downwards and to the left side over the tip of the snout — possibly an artefactual state caused at the time of preservation). There are no traces of any pre-orbital projections. The nares open facing directly posteriorly, from a nasal bulge located 3/8 of the distance from the anterior orbital rim to the tip of the snout. The guiar crest is composed of a continuous series of 24 low cones between the mentum and the angle of the jaw, and continues posteriorly as an even lower series of enlarged midline belly tubercles to the vent. The skin on the sides of the throat are incised by shallow grooves (6 on the left and 5 on the right). The dorsal crest begins at the nape with 3 isolated small cones and is then followed by somewhat triangular laterally flattened tubercles that enlarge successively in groups of 2 to 3 along the dorsal ridge. The crest fades completely by the sacrum and then continues as a low series of angulated tubercles to again fade by the mid tail. Background scalation heterogeneous but not particularly coarse. A single row of slightly enlarged tubercles extends from the shoulder region over the upper third of the flank towards the pelvis. Belly covered with finer almost homogeneous flattened tubercles. The skin of the circular eyeball is covered in roughly homo- geneous
