T. j. jacksonii The T. j. jacksonii is the nominated subspecies, which is commonly known as the Jackson's chameleon. It has the largest natural range of distribution compared to the other two subspecies. T. j. jacksonii grows up to 8 to 10 inches in size. Both males and females have three horns, but that of the females are smaller. 2 Introduction to the Systematics of Trioceros jacksonii (Boulenger, 1896) The Jackson's Chameleon, Trioceros jacksonii, was described in 1896 under the name Chamaeleo jack- sonii in Ann. Mag. Nat. Hist., London, 17: 376, based on a single male specimen (holotype), collected by Colonel F.J. Jackson and deposited in the British Museum of Natural History in London, under the collection number This taxon is distinguished from the other two subspecies (T. jacksonii jacksonii and T. jacksonii merumontanus) by having a greater snout-vent length (SVL; mean 123.7 mm vs. 104.6 mm and 78.4 mm, respectively), more convex postocular and occipital scales, light parietal and dorsal crest scale pigmentation, a greater number of interorbital Machakos Hills Jackson's Chameleon (Trioceros jacksonii jacksonii). This is a smaller Jackson's than the Yellow-crested. This one is found in the Machakos Hills region in Kenya. The males have the three horns and a bright yellow splash across their flank and blue cheeks. The females have one to three horns.
