PONGO 203 
4 feet 2 inches in height, measured fairly to the heel, so as to give the 
height of the animal if it stood perfectly erect; the extent of the 
outstretched arms from 7 feet 2 inches to 7 feet 8 inches; and the 
width of the face from 10 inches to 13% inches. * * * On the 
whole, therefore, I think it will be allowed that up to this time we have 
not the least reliable evidence of the existence of Orangs in Borneo 
more than four feet two inches high.” 
Pongo abelii was described by Dr. Clarke (1. c.) as an Ourang- 
utan of remarkable height from the Island of Sumatra. It was stated 
to be from 7 to 8 feet high, which, if the measurements were correct, 
makes it the tallest Ourang of which we have any record. But 
measurements, unless made by an expert, are apt to go astray, and 
during the nearly one hundred years since this animal was captured, a 
very considerable number of these Apes have been procured in Su- 
matra, and none have fairly approximated the dimensions of Clarke’s 
Ourang; and we are led to suspect either the measurements given were 
incorrect, from the skin having become stretched, or the tape had 
been wrongly applied, and that the animal was merely an extra large 
individual of the ordinary Ourang, for there is nothing in the descrip- 
tion, save size, to indicate that it was a different species. And if there 
was a race of gigantic Ourangs in north west Sumatra, it would be 
strange that during the last century another example had not been 
obtained. Until we have more knowledge of a huge Sumatran Ourang, 
it will be wiser to regard P. abelii as the same as the others procured 
in the island.

The above is an upright skull with a much less lateral depth, 203 
to 239. The braincase is fairly large, rounded on top with a low bony 
crest rising from the posterior part of the frontal, and going to the 
occiput where it joins the lateral expansion of the occipital region. 
The facial region is horizontal and the rostrum broad and short, stand- 
ing at a right angle to the face. Orbits large and close together and 
the cheek bones are broad. Another skull of an adult male also
