Family CAMELID^l. 



The nearest living allies of this family are the Tragulidce, and it 

 is therefore placed here and followed by the ancestral Poebrotheriidce, 

 as it is inadvisable to separate the Tragulidce from the allied Dicho- 

 dontidcK. The teeth are selenodont and quadricolumnar, but of 

 somewhat simpler structure than those of the Pecora. The navicular 

 and cuboid are separate, but the metapodials unite into a " cannon- 

 bone."

Dentition. In normal adult specimens of the two existing species 

 the dental formula is I. ^, C. j, Pm. |, M. |, that of the milk-teeth 

 being I. |, C. ~, Mm. |. The penultimate lower milk-molar is 

 usually shed at a very early age. In one adult skull in the Museum 

 (No. 41. 1. 12. 1) there are four upper premolars on the right side, 

 the last three of which are molariform, the small abnormal tooth 

 being probably a persistent milk-molar. In another recent skull 

 in the Museum there are two lanariform upper premolars on 

 either side, the second pair being probably an instance of redupli- 

 cation. In the two Siwalik species the permanent dentition is the 

 same as in the recent forms ; but in at least one of the fossils the
