arms to wrists like back; outer and inner sides of legs gray, dark and 
light hairs being equally mixed; hands and feet grayish brown; tail 
grayish white; ear tufts white; face dark, lips white. _ 
Measurements. Total length, 1,389; tail, 824; foot, 177; ear, 30.

Although Mr. Thomas says this example is “obviously not an 
albino,” yet the coloring is so entirely abnormal both of the fur and 
face, and also of the hands and feet, that it is most probable it will 
eventually prove to be an albinistic individual of a dark-colored species, 
just as the PITHECUS PHILIPPINENSIS Geoff., proved to be an albino of 
the dark animal the same writer called afterward palpebrosus.
