28106. The greater portion of the right ramus of a somewhat 

 smaller but otherwise indistinguishable mandible, con- 

 taining all the cheek-teeth except pm. 2, in a well-worn 

 condition. Presented by Colonel Colvin. 



16387. Part of the right ramus of the mandible, containing the 

 four last cheek-teeth, in an early condition of wear. 



16260. Fragment of the right ramus of the mandible of a very 

 large individual. This specimen shows the second and 

 third lobes of m. 3, and is remarkable for the extraordinarily 

 large size of the external accessory columns. 



16309. Fragment of the right ramus of the mandible of a large 

 specimen, containing m. 1 and m72, in a slightly worn 

 condition. 



16258. Fragment of the left ramus of the mandible containing pm. 4 



and m. 1. 

 16385. Part of the right ramus of the mandible, containing pm. 4 



and m. 1, in a very much worn condition. 



16168. Fragment of the right ramus of the mandible with pm73. 



16306. Part of the left ramus of the mandible, with the three true 

 molars (3rd imperfect), in a much worn condition. 



16243. The much worn second right lower true molar. 



16398. The third right lower true molar. ^Neither this nor either 

 of the three following specimens shows any trace of an 

 external accessory column. 



16262. The third right lower true molar, in an unworn condition. 



16249. The third left lower true molar, in an early stage of wear. 



16245. The third right lower molar, in a similar condition of wear. 



15288. The nearly complete mandible of a young individual, showing 

 the three milk-molars of both sides and the right canine. 

 The teeth of this specimen agree very closely with those 

 of the somewhat older jaw figured by the present writer 

 in the ' Palseontologia Indica,' ser. 10, vol. ii. pi. xxi. fig. 3 : 

 there are large outer accessory columns in mm. 3. There 

 is a very similar specimen in the Dubliu Museum of 

 Science and Art (vide Journ. E. Dublin Soc. ser. 2, vol. iii. 

 p. 79 1 ). 



1 The writer was unaware of the existence of this specimen when noticing 

 the Dublin jaw.
