 Anselme Gaëtan Desmarest described the Malayan tapir in 1819; the Sunda stink badger and "Paradoxurus hermaphroditus bondar", a subspecies of the Asian palm civet in 1820; the Sunda pangolin, the Malayan weasel and the genus of "Semnopithecus" in 1822.In 1821, Raffles published descriptions of the species jointly collected by Duvaucel and Diard in Sumatra, including first descriptions of the sun bear, the binturong, the crab-eating macaque, the Sumatran surili, the siamang gibbon, the silvery lutung, the large bamboo rat, the large treeshrew and the cream-coloured giant squirrel.The many drawings, skeletons, skins and other animal parts that Duvaucel sent to the Paris Museum of Natural History included head, skin and paws of a species "from the mountains north of India" that his stepfather's brother Frédéric Cuvier described as "Ailurus fulgens" in 1825.
