is superolateral, pierced in a large semidivided nasal scale. The eye is moderate in size, with a vertical pupil. The body is slightly laterally compressed. The tail is short. About 41 to 45 rows of dorsal scales cross the snake's back, and 257 to 287 ventral scales are seen along the lower surface. A single undivided anal scale is found immediately in front of the anus, and 38 to 53 subcaudal scales are on the lower surface between the anus and the tip of the tail, all or mostly in two rows. The polymorphic variant known as the Stimson's python has much stronger and more variable colors; often being adorned with reddish-brown to chocolate blotches against lighter tan. The rostral is broader than high, barely visible from above. The internasals are slightly longer than broad and are shorter than the anterior prefrontals. The second pair of prefrontals is in contact at the midline, or is separated by a small shield. These posterior prefrontals are sometimes broken into several shields. The frontal is one and a half times as long as broad, slightly shorter than its distance from the end of the snout, longer than the small parietals. Three to 10 small loreal shields are present, some almost granular, with 11 to 13 upper labials. Three or four of the posterior lower labials have deep pits. The anterior maxillary teeth and anterior mandibular teeth are very long, gradually decreasing in size posteriorly. The premaxillary bone also has teeth. Geographic range A. childreni is found in Australia in the extreme north of Western Australia, the northern third of the Northern Territory, and northern Queensland, and also on the islands of the Torres Strait. The Stimson's python variant is found throughout an even greater range; it occupies much of the interior of Australia, from Queensland to Perth. The type locality is given by Gray (1842) as "—?", is listed as "N.W. Australia" by Boulenger (1893) in his Catalogue of the Snakes in the British Museum (Natural History). Volume I., and is listed as "unknown" in Stimson (1969). A. childreni occurs specifically in the region spanning the coast between the Kimberleys in Western Australia to Mount Isa in northwestern Queensland. Habitat Children's python is found in a variety of natural habitats, including forest, savanna, shrubland, desert, grassland, and freshwater wetlands. In Alice Springs the cosmopolitan tick Amblyomma limbatum has been collected from a Children's
