sentences:  The New Guinea crocodile was first described by the American herpetologist Karl Patterson Schmidt in 1928 as "Crocodylus novaeguineae".At one time it was thought that there were two subspecies, "C. n. novaeguineae", the New Guinea crocodile native to Papua New Guinea and Western New Guinea, and "C. n. mindorensis", the Philippine crocodile, native to several islands including Busuanga, Luzon, Masbate, Mindoro, Negros, Samar and Mindanao.Most authorities now consider that the Philippine crocodile is an entirely separate species.
