with four ill-defined tubercles; canines small. . 
In the Paris Museum is a specimen of a Chimpanzee marked 
Troglodytes tschego type. All the hair has gone from the head and 
left shoulder, and these parts have been covered by the taxidermist 
with a skin of CoLoBUS VELLEROSUS, but the right shoulder and arm as 
well as the body possess their own natural hair. Of course the hair on 
the head is now long and there is a rather thick whisker, but this 
arrangement must cause a very different appearance from that which 
the animal presented in life. Tschego has always been regarded as an 
entirely black Ape, but this example while it is black on shoulder and 
arm and to the middle of the body, has the remaining portion, together 
with the legs a wood brown; the hands, feet, and face are black. 
Length of head and body 36 inches. 
Measurements. Skull: total length, 190; occipito-nasal length, 
149; intertemporal width, 72; width of braincase, 99; Hensel, 136.9; 
zygomatic width, 129; width of rostrum at canines, 58.8; palatal length, 
67.9; length of upper canines, 27.4; length of upper molar series, 53.5; 
length of mandible, 150.3; length of lower molar series, 49.1. Ex 
type Paris Museum, of T. tschego.
