2665. The skull of a young male Elephant. 



The lower jaw is attached, and the right tusk- in place : it curves inwards. The molar 

 teeth present a peculiarity. The chief part of the one which is in use exhibits the summits 

 of ten plates on the left, and of eleven plates on the right side ; these appear to be the last 

 plates of the third or fourth molar, from the fore part of which some plates have been worn 

 away. On both sides of the jaw this molar is continuous with a larger posterior one, the 

 division being indicated by a slight constriction on each side of the tooth, by a thick mass of 

 cement, and by a process from the outer and inner borders of the alveolus which fits into the 

 base of the lateral constriction. The first four plates of the second confluent tooth have 

 begun to be worn from the left side. The molar teeth hi the under jaw present the same 

 peculiarity, the boundary between the two confluent teeth being indicated on the right side 

 by lateral constrictions, and corresponding growths from the borders of the sockets. The 

 length of this skull is 23 inches.

 tusk has been exposed, and the tusk removed. The malar bones are wanting. The length

 third molar consists of thirteen plates, nine of which have been in use. The length of this 

 skull is 19 inches.
