374 Savage and Wyman 



No. III. Young. The skeleton to which this cranium be- 

 longs, was prepared by Dr. Winslow Lewis, Jr., and deposited 

 in the Society's cabinet. Its entire length is twenty-seven 

 inches, and it is supposed to be about twenty-two months old, 

 and was born on shipboard while the mother was on her passage 

 from Borneo to the United States. The mother was reported 

 to have been born in Borneo, but I have learned from the 

 officers of the vessel, that she was carried there from Africa. 

 The skin which is now^ in the Boston Museum, has all the 

 characteristics of the African Ourang, and the skeleton also 

 conforms w^ith it. 



The frontal bone consists of a single piece, the suture be- 

 tween the two lateral portions having entirely disappeared. 

 The superciliary ridges though less strongly marked than in 

 the adult, contrast strongly with the same parts in two crania 

 of the young satyrus, with which I have compared them. 

 The squamous suture and its ad dit amentum form a nearly con- 

 tinuous horizontal line, and the two extremities are nearly 

 equidistant from the auditory foramen. A small os triqueirum 

 exists at the union of the occiput with the parietals. Occipital 

 bone approaches the quadrumanous type in having its lateral 

 edges nearly parallel, so that the suture by which it is united 

 w^ith the surrounding bones has no longer the lambdoidal 

 shape, and its inferior portion which is posterior to the foramen 

 magnum is nearly quadrangular. Temporal bone reaches the 

 frontal, separating the sphenoidal from the parietal. 



Only one infra-orbitar foramen on each side ; no supra- 

 orbitar foramen existed. Ossa nasi were disunited, but there 

 existed no trace of the intermaxillary sutures. 



Dental formula, incisors | canines = molars | total 18. The 

 two central incisors of the lower jaw, if they had ever appear- 

 ed, had fallen ; no alveolus, however, was detected. 



Vertebral column. In its general conformation the verte- 

 bral column does not differ materially from that of man, 

 excepting in the length of the spinous processes of the cervi- 

 cal, and the comparative size of the lumbar and dorsal verte- 

 bra?. With regard to the vertebrie of the neck, Prof. Owen
