and has therefore, together with the posterior part of m\ probably 

 been in contact, during the act of mastication, with m ^ in the upper 

 jaw. m ^ in both portions has the ends of the tubercles worn, pro- 

 bably by contact with m ^ in the upper jaw. As regards size, the two 

 back molars are about equal. 



In the raature female the teeth are as follows: 



In the upper jaw the two incisors have only been slightly deve- 

 loped, and are worn at the points, so that no part protrudes beyond 

 the Wide and irregulär alveolar border. 



Of the molars only two are in function, the posterior one con- 

 siderably larger than the anterior. In front there is an empty socket 

 filled up with bone tissue, behind which follows a molar, almost circular 

 in section, and worn quite flat on its upper surface. The innermost 

 molar is long, and divided into a front and back portion. The first 

 is about the size of the preceding molar; the back one is twice as 

 small. Both teeth are greatly worn. In the lower jaw the sockets 

 on the Symphysis are partly filled up with bone tissue, but all are 

 still visible. 



The molars are two, formed on the whole like those in the 

 upper jaw; the first is almost circular, the next oblong and somewhat 

 contracted , but the back part of the tooth is here but slightly sraaller 

 than the fore part. 



Both are much worn. An empty socket is found both before and 

 behind the two functional molars.
