The taxonomic history of the recent forms of Sumatran Rhinoceros (Dicerorhinus sumatrensis).

Journal of the Malayan Branch of the Royal Asiatic Society 57 (1): 12-25, figs. 1-6.

Abstract:

William Bell gave the first description of a double-horned rhinoceros shot in Sumatra. Based on this report, the animal was named by G. Fischer in 1814. The arrival in the  London Zoo of a specimen from Chittagong and another from Malaya in 1872 caused the first interest in the taxonomy of this group resulting in the description of three new species. At present, one species with three  recent subspecies is recognised.
