The small superior canines have much the same form as in 

 Auchenia, hut are relatively thicker transversely. 



As in Auchenia, small papillae which may be present behind 

 the canines indicate the existence of rudiments of the anterior 

 premolars.

P 3 as shown in no. 20040 (fig. 2) has a narrow, almost blade- 

 like crown with a very small cusp, or a prominent ridge of the 

 eingulum high up on the postero-internal wall. It shows approxi- 

 mately the same size compared with P 4 that is noted in Auchenia. 



P 4 has a relatively greater transverse diameter than in 

 Auchenia and a more distinctly quadrate form. In this respect, 

 it more closely approaches the form seen in Camelus.
