Abstract Acrochordus dehmi n. sp., an aquatic piscivorous serpent from the Chinji and Nagri formations (upper Miocene) and the Dhok Pathan formation (lower Pliocene) in northern West Pakistan belongs to a family unknown in fossil form, and a genus no longer inhabiting the Indian peninsula. Its nearest living relatives are in the Bangkok region of Thailand, 3,500 kilometers distant. A size of 2.5 meters was attained in the upper Eocene, but the largest found in the lower Pliocene is 2.0 meters. The difference may represent only a smaller sampling from the lower Pliocene. One vertebra of an extinct python was found in the lower part of the Chinji formation, but lack of additional information precludes a description of the species.
