Banded Surili, Indonesia (USNM 144088)

Old World monkeys are primates and are more closely related to humans and apes than any other living nonhuman primate group. The Smithsonian Institution’s Division of Mammals ( houses many Old World monkeys in its scientific collections.

This type specimen, USNM 144088 (, is a female banded surili (Presbytis femoralis percura) from Indonesia. This specimen was collected by William Abbott  in 1907 near Kompei on the island of Sumatra. This individual weighed 15.75 lbs, had a total length of 1,150 mm, a tail length of 660 mm, and a hind tarsus length of 177 mm. In 1908, M. W. Lyon designated this individual the type specimen Presbytis percura.

This is a CT scan of the mandible of USNM 144088. These three-dimensional scans are made publicly available through the generous support of the Smithsonian 2.0 Fund, provided from the annual gifts of the Smithsonian National Board to the Secretary to use at his discretion (, and the Smithsonian Collections Care and Preservation Fund.

The main goal of this joint initiative between the Human Origins Program and the Division of Mammals is to make the NMNH's scientific collections of our closest living relatives, the apes, available in 3D for education and research.
