SIMIA,. 



which appears not to have cheek swellings, but in its squat, 

 powerful build and short fingers it was evidently not that race. 



d. The skin and skull, of an adolescent male. This speci- 

 men is nearly uniformly coloured dark maroon, darkest 

 on the head and ferruginous on the back of the thighs, mou- 

 stache and beard. The hair is long, with the exception of that on 

 the middle of the head, but the direction of the hair on this 

 region and external to it is the same as in the adult animal first 

 described. The moustache and beard are only partially de- 

 veloped. The face is sparsely covered with short red hairs. 

 The cheeks did not present any trace of swellings. 



The milk canines are still present, and there is no trace ex- 

 ternally of the permanent teeth. The front pair of the upper 

 permanent incisors are fully through, and the outer incisor of 

 the right side is also present, but its fellow of the opposite 

 side is only appearing. The penultimate molar had been in 

 full functional activity. The front incisors are very broad and 

 the molars are very large. The palate is long, broad, and 

 deep. The orbits are small and round, but flattened above, 

 and the interorbital area slopes slightly forwards, and 

 the maxillae are much forwardly directed. From the upper 

 margin of the nasals to the anterior border of the foramen 

 magnum is 4''05, and from the latter point to the anterior 

 margin of the premaxillse measures 5'"66. As yet there is no 

 sagittal ridge, the ridges being only feeble raised lines, separ- 

 ated from each other by more than two inches.. This character, 

 however, in a male Orang skull is only an indication of youth, 

 whereas it is a characteristic feature of the more delicately 

 formed female skull. The skull presents a depression near 

 the upper border of the left parietal, and another on the right 

 orbit, but similar depressions of this nature are better illus- 

 trated in one of the succeeding adult skulls. Presented by 

 the Zoological Gardens, Calcutta, 29th April 1880. 



e. A stuffed nearly adult female with its skull and hyoid 

 bone, and the uterus in alcohol. The hair is long and dark 

 maroon, approaching to blackish on the body generally, but on 

 the back of the thighs it is a pallid ferruginous. The hair on 

 the head is long and directed forwards, longest in the temporal 

 region, and the face is sparsely covered with short hairs. The 

 moustache is only very feebly indicated, and also the beard. 

 This animal lived for about one year and a half in the Zoological 

 Gardens,. Calcutta, and. at its death it measured 3 feet 8-50 

 inches from its heel to the vertex, and the stretch of its arms 

 was 6 feet 4 inches. The skull has very much the same form 

 as in the preceding male. The skulls so closely resemble each
