Ten years later, T. Harrisson (1949) wrote, `There are now almost certainly no rhinoceros left in Sarawak', although he was able to report observations in 1946 from the upper S. Padas, in Sabah, and in 1945 from S. Raya and from high ground in the upper S. Bahau in Kalimantan. In the Kelabit uplands Harrisson later found (Harrisson, in Davis, 1958) that `the Sumatran rhinoceros, once common in the area in the last century even breaking fences around padi fields - has not been reported anywhere in the area for twenty years. There are living Kelabits who have killed more than ten'.
Harrisson (1961b) later suggested that there were then `probably not more than thirty in the whole island'. J. L. Harrison (pers. comm., 1962) saw tracks on G. Kinabalu.
P. F. Burgess (in litt., 1963) found reliable evidence of animals surviving at S. Bole on the Segama, the Dent Peninsula, upper S. Kalumpang and Ulu Kuamat, Sabah. A less pessimistic estimate of numbers in eastern Sabah was given in 1970 (Anon., 1970), but was not corroborated by detailed evidence. A 5-day search in 1972 of an area in Ulu Karamuak, Sabah, where rhinoceros had been present in 1960, produced no evidence of any surviving animals (Sandilands, 1974). In 1976, tracks were found, and a provisional sighting made, in the area of the proposed Danum reserve, S. Segama, Sabah (D. R. Wells, pers. comm.). The decline and near extermination of the species throughout its world range have been documented by van Strien (1974).

Genus DIDERMOCERUS Brookes, 1828. Application has been made (Boylan & Green, 1974) to the International Commission on Zoological Nomenclature to suppress the generic name Didermocerus in favour of its synonym Dicerorhinus Gloger, 1841. By this action, the valid systematic name of the Sumatran Rhinoceros would become Dicerorhinus sumatrensis, usage already adopted by several authors including Groves (1967) and Groves & Kurt (1972).
