Maroon Langur, Indonesia (USNM 125157)

USNM 125157

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 125157 (, is a female maroon langur (Presbytis rubicunda carimatae) from Indonesia. This individual was collected in 1904 by William Abbott near Telok Adar on Karimata Island off the west coast of Borneo. This individual weighed 16.75 lbs, had a total length of 1240 mm, a tail length of 710 mm, a hind tarsus length of 169 mm, and a head to body length of 530 mm.  In 1906, G. S. Miller designated this individual the type specimen of Presbytis carimatae.

This is a CT scan of the cranium of USNM 125157. 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 nonhuman primate relatives available in 3D for education and research.
