It is commonly asserted that the ligamentum teres is absent in. the Orang,
as also the pit for its reception on the head of the femur (1). I find no trace
of the latter in either femur of any specimen, with one exception (2); but in that.
exceptional specimen each femur (Pl. XL. fig. 7 i) exhibits a small but distinct
depression on its head in the place occupied in other forms by the pit for the round
ligament. This absence has not, as far as I am aware, been noticed in Man or the
Chimpanzee; but. in the Gorilla I have sometimes been unable to detect any trace
of such a fossa on the head of the femur (3). It may therefore be the case that
this ligament is occasionally absent in the Gorilla, and occasionally present in
the Orang.

Quote p. 214
The Orang differs from every other Primate without exception in: — the great
absolute length of the pectoral limb minus the manus, of the manus itself, of its
third digit both with and without its metacarpal, and of the metacarpal of the pollex;
the great difference between the length of the pollex and that of the index; the
large diameter of the acetabulum compared with the length of the spine; the small
proportion borne by the femur to the humerus; the very obtuse angle formed by
the neck of the femur with its shaft; the all but constant absence of the pit for
the ligamentum teres on the head of the femur; the shortness of the tibia compared
with the humerus; the length of the pes compared with that of the rest of the pelvic
limb; the length of the pes compared with that of the tibia; the absolute length
of the three middle metatarsals; the absolute length of the longest digit with its
metatarsal; the very small proportion borne by the length of the hallux to that
of the longest digit of the pes; the occasional absence of the second digit of the
hallux; the great length of the index, with its metatarsal, compared with the length
of the spine; the small length of the hallux (both with and without its metatarsal)
compared with that of the whole pes; the great length of the index, without its
metatarsal, compared with that of the whole pes; the nearly equal length of the
indices of the pes and manus, both with and without the metatarsal and metacarpal;
the shortness of the tarsus compared with the length of the pes. Thus the Orang
is one of the most peculiar and aberrant forms to be found in the order Primates.
