eyff, and h. Its incisors are very much smaller tban those of 

 either e or g, but the incisors of h are so much ground down 

 that their original dimensions can only be guessed atj but they 

 appear to have been about the size of those of this specimen. 

 The muzzle, however, of h is very much larger than the muzzle 

 of this skull and measures 2*'50 across, while this muzzle is 

 only 2*"11 and very much shorter. The muzzle of e is ^'''SO, 

 while that of ^, in which the canines are only partially through, 

 is as much as Z^'^O. The orbits of this specimen resemble those 

 of g, but differ greatly in appearance from the vertically elon- 

 gated orbits of h, which are 1*'85 in vertical height as compared 

 with l"-50 in this individual. These few details suffice to 

 show how great is the individual variation among the skulls of 

 Orangs, the animals of which were apparently identical in life. 



There is a well-marked indentation on the left half of 

 the parietal, and a long rugosity on the temporal ridge of that 

 side. Presented by W. Rutledge, Esq., 3rd March 1879. 



Jc. A stuffed female: general colour as in the previous 

 females ; viz., dark maroon, but with short and somewhat 

 sparse hair, probably due to the effects of confinement. Pre- 

 sented by W. Rutledge, Esq., 12th January 1870. 



I. The flat skin and skeleton of a young male, dark 

 maroon like the preceding animals. Although this Orang had 

 cut only its first molar teeth below and above, its skull is as 

 long as the female skull _/, which conveys some idea of the great 

 difference in size between the sexes. The general appearance 

 of a male skull at this period is that of a female, there being 

 no muscular ridges developed beyond the feeble temporal ridges, 

 which are far apart. The orbits of this skull are large and 

 obliquely placed ovals. Presented by W. Rutledge, Esq., 3rd 

 March 1879. 



m. A young male, in alcohol, with no ti'ace of cheek excres- 

 cences, a rather large head, with abroad and deep muzzle, and 

 with short and rather sparse hair. The hair short on the 

 head, and deep maroon throughout. Presented by W. Rut- 

 ledge, Esq., 20th March 1879. 



n. The skin, skull, and bones of the trunk of a young male. 

 General colour maroon, passing into bright ferruginous on the 

 back, and still lighter on the back of the thighs, and d.arkest 

 on the head and arms. The hair is long and distributed 

 in the same way as in the foregoing animals, from which 

 this individual differs only in its brighter colour, paler face, 

 and fleshy colour around the eyes and about the mouth. This 

 colouration of the face has distinguished, more or less, all the 

 young Orangs that have passed under my observation, — they
