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

This specimen, USNM 142238 (, is a female Bornean slow loris (Nycticebus menagensis) from Indonesia. This individual was collected by William Abbott in 1905 near Sanggau on the island of Borneo. This specimen had a total length of 286 mm, a tail length of 13 mm, a hind tarsus length of 60 mm, and a head to body length of 273 mm.

This is a CT scan of the mandible of USNM 142238. 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.
