SIMIA. 7 



SO broad J these differences being probably due to the effects of 

 confinement, as the previous specimen d was only a few months 

 in captivity before it died, whereas this animal was nearly three 

 years in confinement and at a period when its teeth would have 

 doubtless attained a greater development had it been in a state 

 of nature.' The brain case, although not so high as in it, is 

 fuller and broader. The last molar is not visible, and the outer 

 upper incisors and the canines, above and below, are only 

 coming through. The parietal ridges are mere lines, far apart. 

 From the upper margin of the nasal to the anterior border of 

 the foramen magnum measures 3''"55, and the length from the 

 incisor border of the premaxillaries to the foramen magnum is 

 5'-10.

g. The skin and skull of an adolescent female. Dark 

 maroon, darkest on the head and arms, ferruginous on the 

 back of the thighs. The hair is long, and directed forwards 

 on the head, as in the previous examples, which it closely 

 resembles. 



The skull is like that of e, but the muzzle is not so 

 forwardly projected. FrOm the upper end of the nasal to the 

 foramen magnum is 3*" 70, and from the latter to the front of 

 the premaxillary measures 5*'40. The temporal ridges are 

 far apart. The incisors are large, but not quite so large as in 

 that skull. The permanent upper incisors are appearing, and 

 the last molar is visible through a small opening in the alveolus. 

 The molars are not quite so large as in e. 



The atlas is firmly anchylosed to the skull at the condyles 

 on both sides, and on the left side the bone is amalgamated 

 with the skull at the condyle and along nearly one-half of the 



' This animal, after living in the Zoological Gardens, Calcutta, for about 

 18 months, was suddenly deprived, hy death, of the female (e), who had 

 been his constant but distant companion during that period. Her death 

 afEected him much, as it did also the young female who had been reared by her, 

 and who was believed to be her child. The male appeared to pine and used to 

 sit outside, on the top of the large house in which they were kept, looking ill the 

 direction in which the dead body of bis companion had be,en carried away. 

 During the day he could not be induced to go into his house for shelter from 

 the blazing sun. The result was, that one very hot day, in the end of April, he 

 came down from his look-out in a dazed condition, apparently blind and 

 staggering. He never rallied, and at last he became paralysed and died 7 

 months afterwards. 



The young female, when her supposed parent, hut if not so, tender foster- 

 mother, was carried away dead, exhibited all the signsof deep grief, emitting a 

 wailing sound, but no tears, attempting to follow the body, and, when driven 

 back, crying and rolling on the ground in a paroxysm of grief.
