522 Remarks on the different species of Orang-utan. [No. 6. 



the shoulder-blades and rest of the pelvis; the epiphyses being 

 completely soldered. The limb-bones are even rather longer than 

 in the great female JPappan, and in fact exceed in length those of 

 any other of our full-grown specimens : the humerus measuring 15 

 in. ; the ulna (to tip of styloid process) 15f in. ; femur 11| in. ; and 

 tibia 10£ in. : circumference of middle of trunk of humerus 3i in. ; 

 and of femur 2-f- in. The few digital bones seem to accord in dimen- 

 sions with the corresponding bones of our male JPappan. The ex- 

 treme length of the scapula is 8-f- in. ; and of pelvis lOf in : clavicle 



8 in. This specimen is marked as having been procured in Sadong 

 (in Borneo). 



The next specimen, which was erroneously marked Pappan, we 

 consider to be a small female Rambi, though fully mature and even 

 old, as shewn by the almost complete obliteration of the cranial 

 sutures, the anchylosis of the various epiphyses, and the amount of 

 attrition of all the teeth. The cranial ridges are very small ; and 

 the sagittal crest is hardly at all raised, but nevertheless exhibits a 

 tendency to rise along the median line of the skull, between the 

 frontal ridges which converge from the temples, and to be prolonged 

 in front, anterior to the convergance of the latter, which takes place 

 unusually far back : the nasal bones are united and singularly 

 minute, actually not rising so high as the wide part of the orbital 

 cavities ; and the latter are small and circular, measuring barely If in. 

 every way. The skull considerably resembles that of the female Rambi 

 formerly figured, only that the sagittal crest is so much smaller ; 

 the zygomata being also more raised (in consequence of the greater 

 prolongation of the condyle process of the lower jaw) ; and the 

 orbits are smaller and more circular, and surmounted by much 

 slighter ridges : consequently the face is flatter, and the sockets of 

 the incisors are also less protruded. The skeleton is unfortunately 

 very imperfect, wanting most of the bones of the hands and feet, 

 and one tibia SLn&fbula : a portion of the lower jaw, with the canine, 

 first prse-molar, and part of the second, is also lost : but the other 

 long bones are present, and the pelvis is complete. Length of 

 humerus but 13£ in. ; of ulna 13f in. ; of femur 10f in. ; and of tibia 



9 in.: circumference of middle of humerus 2| in.; and of femur 

 2f in : metacarpal bone of middle finger 3[f in.; metatarsal of
