ABSTRACT
From the form of the pelvis, and from the inferior longitudinal extent of the molar series as compared with that of the lower jaw of Dr. Clarke Abel’s Sumatran male Pappan, also from the inferior size of the hand and foot as compared with these members in Dr. Abel’s specimen, I have considered the skeleton of a Pappan now presented by Mr. Nicholls to be that of a female animal; but not without considerable hesitation.* We have no male pelvis of an adult Orang for comparison; but two of undoubted females of the small species, and one of these (that of the animal which passed its life in close captivity) is singularly narrow, and probably differs little from a male pelvis. The skeletons of adult Mias Rambi and of adult of the small Chimpanzee figured by Prof. Owen in the first volume of the “ Transactions of the Zoological Society,” are also those of females ; and Mr. Owen gives 5 in. 5 1. as the antero-posterior diameter, and 4 in. as the transverse diameter of the pelvic aperture of his adult female Mias Rambi, the corresponding diameters of the pelvic aperture of our Mias Pappa?i being 5 in. and 4 in., in our aged female Mias Kassar 4 ^ and 3J in., and in our adolescent female with the comparatively short fore-arms 4 ^and 2\ in. (!); which last are probably the permanent male proportions, to which I suppose Dr. Kneeland refers when he mentions “ the narrow elongated shape of the Orang’s pelvis.” f
