joins the frontal (u), answers to the tubercle. The indications of a lacrymal canal are 

 minute in all Wombats. The lacrymal of Phase. Mitchelli (Plate L. fig. 3, 73) shows 

 the well-developed tubercle (t) in the same relative position to the fronto-maxillary suture 

 as in Phascolomys vombatus and Phase, platyrhinus : the bone anterior to the tubercle 

 is flatter, less excavated in Phase. Mitchelli than in those existing Wombats, and herein 

 more resembles the lacrymal in Phascolomys latifrons. 



The alveoli of the five upper molars of each side (Plate L. fig. 5, p 3, 4, m 1, 2, 3) with 

 the intervening part of the bony palate (ib. 20, 21) are preserved in the present fossil. 

 The form of the latter adheres to the type of that of Phascolomys vombatus and Phase, 

 platyrhinus (Woodcut, fig. 7) ; in Phase, latifrons (Woodcut, fig. 8) the palate (20, 21) is less

 does not reach that of the hindmost socket (m 3) in the fossil, which also in this respect
