to the middle ; and the basal portion overlies, to some extent, 

 the upper part. When perfect this tusk could not be less than 

 two inches long, and is about an inch wide at the base. 



Four teeth, upwards of half an inch long, lie upon the base of 

 this large tusk, and another, about the same size, lies pressed 

 down a little in front of it ; these have their bases attached to 

 the maxilla, and are the only maxillary teeth of this side, a 

 very small portion of the maxilla being present. In front of 

 these teeth a short space intervenes between them and the base 

 of a large tooth, which stands erect, and is f ths of an inch in 

 diameter ; the crown lies pressed in contact with the basal por- 

 tion, and with it measures nearly an inch in length. A large 

 depression is immediately in advance of this tooth, separating it 

 from two other teeth equally large, or, perhaps, a little larger, 

 which are crushed down confusedly, one over the other, at the 

 anterior extremity of the specimen. These three large teeth 

 would seem to belong to the prsemaxilla. The teeth of the 

 maxilla of the right side are well displayed ; they stand up, 

 for the most part arranged along the alveolar ridge with their 

 crowns (some of which are perfect) inclined backward and in- 

 ward. There are thirteen of these teeth ; they vary somewhat 

 in size, and commence in front in a line with the base of the 

 vomerine tusk. The first seven are placed close together ; the 

 first and seventh are larger than the rest, and are Jth of an inch 

 wide at the base ; two or three of the smaller have the crown 

 complete ; when perfect, the large ones must have been upwards 

 of half an inch long. A short space now intervenes in the 

 series, and then there is a cluster of four more teeth, three of 

 which are rather large and one small, the latter being placed 

 between the first and second of the three ; all their crowns are 

 broken ofi"; the bases of the three larger measure :^th of an inch 

 in diameter. Behind these is a large depression ; and then the 

 series is terminated by the two last teeth, the twelfth and thir- 

 teenth, which are placed near to each other. All that remains 

 of the former is a very short stump, almost ;^th of an inch in 

 diameter ; the latter is apparently quite small, and is represented
