518 Bemarhs on the different species of Orang-utan. [No. 6. 



The short vowel, on the other hand, is already fully subjected to 

 the modified mode of expression in the Buddha Grupta inscription. 



The Gujrat copper-plates of later days do not however, accept 

 these new forms, but adhere to the general outline of the ancient 

 superposed vowel.* 



Further remarks on the different species of Orang-utan. — By

Our museum having received from Sir James Brooke of Sarawak 

 the superb donation of seven skeletons of large adult Orang-utans, 

 I hasten to communicate the results of my examination of them, 

 as a sequel to my former memoir on the genus published in the 

 22nd volume of the Society's Journal. 



Of these seven skeletons, five are referable to the Mias Bambi 

 of Sir J. Brooke ; although oue of them (a small but full grown 

 female) is marked by himself M. Bappan ; and another is sent by 

 the new name M. Chapin, which is also that of an old female animal, 

 remarkable for its extraordinarily large and vertically elongated 

 orbits. It is probable that this alleged Chapin merely represents 

 an individual variation ; and Sir J. Brooke states, in his letter an- 

 nouncing the presentation, that some of these skeletons had been 

 labelled by him with the names specified by natives, who, according- 

 ly (as may be supposed in such a case), are not particularly conver- 

 sant with the osteological distinctions of the different species. 



The sixth skeleton is that of an old female of the Mias Bappan, 

 with double-crested skull like that of the male figured in illustra- 

 tion of my former memoir. It even exceeds that male in size, but 

 the skull is smaller ; and the sexual distinctions of the two are 

 unmistakeable. In this female, the epiphyses of the limb-bones, 

 scapulae, ilia, &c. are thoroughly anchylosed, denoting completion 

 of growth ; even the symphisis pubis is united (with much irregular 

 deposition of bone externally), and the saero-iliac symphysis on 

 the right side only. In no other of our Orang skeletons are the
