Bornean White-Bearded Gibbon, Indonesia (USNM 145327)

USNM 145327

Gibbons are apes and one of our closest living relatives. The Smithsonian Institution’s Division of Mammals ( houses many gibbons in its scientific collections.

This type specimen, USNM 145327 (, is a male Bornean white-bearded gibbon (Hylobates albibarbis) from Indonesia. This specimen was collected by William Abbott  in 1907 near the Matan River on the island of Borneo. This individual weighed 25.75 lbs, had a hind tarsus length of 144 mm, and a head to body length of 464 mm. In 1911, M. W. Lyon designated this individual the type specimen Hylobates mulleri albibarbis.

This is a CT scan of the cranium of USNM 145327. 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.
