2871. The sacrum. 



It includes five vertebrae, but only the first two afford articular surfaces for the ilium. The 

 anterior vertebra shows the supplementary articular surfaces at the fore part of the trans- 

 verse processes. 



2872. The right scapula. 



2873. The right humerus. 



The intercondyloid space is perforated. 



2874. The right radius and ulna. 



They are partially anchylosed at their distal ends. 



2875. The ossa innominata. 



They are partially anchylosed at the pubic symphysis. The ilia are oblong quadrate plates, 

 with the upper and hinder angles developed to form the articulations with the sacrum. 



2876. The right femur. 



The medullary artery enters the shaft below the small trochanter, and runs obliquely down- 

 wards. 



2877. The right tibia. 2878. The right fibula. 



2879. The skull of an American Tapir (Tapirus americanus}. 



The superoccipital is narrower and more deeply excavated than in the Malayan Tapir : a 

 smaller proportion of the petromastoid is visible between the exoccipital and squamosal : the 

 frontals are less expanded and less elevated above the nasals. In this skull the last molars 

 are still concealed in their formative sockets. 



Hunterian. 



2880. The skull of an American Tapir (Tapirus americanus). 



The outer alveolar wall has been removed from the right side of both upper and lower jaws. 

 The last molar tooth is protruded, but not fully developed. The last premolar is in place.
