smaller than the anterior lobe of i^, and without a trace ofa central 

 groove. i ^ is divided by a groove into two lobes of about an equal 

 size (in C the groove is but slight). 



The rudimentary socket for the canine is situated (as in H. agilis) 

 further back, than the posterior margin of the foramen incisivum. 



The premolar (p^) is of medium size, rather thick and blunt. 

 Its crown in these two specimens is almost entirely lifted up beyond 

 the level of the first molar, and in the largest specimen it is also 

 strongly directed ontwards. It is probable, that in both specimens it 

 is about to be shed, as in the younger specimen it still retains a 

 normal position. 



The molars increase regularly in size inwards ; m ^ is especially 

 considerably smaller than the other molars. 



In the lower jaw the premolar (p '■') is strongly directed forwards 

 (with obliquely ascending alveolar margin), and is, as that in the upper 

 jaw, somewhat higher than the crown of the nearest molar. Likewise 

 in this is m ^ considerably smaller, than the other molars. 



The young. 



The length of the skull of the young can not be stated. The 

 sutures are quite open ; of the molars, m ^ is just making its appear- 

 ance above the alveolar border ; p ^ and the milk premolar are 

 present. 



In the Upper jaw the margin of i * as yet is nearly even ; P is 

 unusually large, almost twice as large, as that in the mature specimen ; 

 i ^ is not yet fully developed. There is no trace of the canine. The 

 premolar (p^) is in use, rather thick and long, also somewhat smaller, 

 than the milk premolar; the germ of p^ is found above its posterior 

 root. None of the premolars are raised (like ^ ^ in the fullgrown 

 specimens) beyond the level of the molars. In the lower jaw the pre- 

 molar (p^) and the milk premolars are rather smaller, than those in 

 the Upper jaw, and with the first germ of p^ hidden in the jaw just 

 under the space between the two said teeth.
