Habitat: Sumatra (Medan!, Ramolina!, Serdang! in Deli, 

 Danau Kotta & Danau Baru in Indragiri, Blindahan river, 

 Padang Bedagei, Laut Tador, Gunung Sahilan!, Djambi!); 

 Borneo! (Sadong river in Sarawak!, Muka, Sinkawang, Ponti- 

 anak, Bandjermassin, lake Lamuda, Kapuas river!, Muara Te- 

 beh!). Malay Peninsula. 



Note. The Malay Charial, at first known from Borneo only, 

 was discovered in Sumatra and the Malay Peninsula at about 

 the same time (See Nelly de Rooy, in A. Maass : Durch 

 Zentral Sumatra, Rept. 1912, p. 5). It is a freshwater crocodile, 

 feeding on fish and not rare in the Sumatran rivers. Strauch 

 mentions its occurrence in Java (Synopsis Crocodil. 1866, p. 62), 

 but it has never been recorded from there again. This author 

 did not see a Javanese specimen himself, but he says : "Ferner 

 scheint diese Art auch auf Java einheimisch zu sein, zum 

 Mindesten findet sich im Stuttgarter Museum ein Exemplar 

 von dieser Art."
