00 MACEOPODID^. 



Shull and teeth very muoli as in L. leporoides, but the nasals are 

 as a rule slightly less expanded behind, and i.^, the canine, and 

 p.* all somewhat smaller. These points are, however, neither suffi- 

 cient in themselves nor constant enough to supply definite and 

 invariable means of distinguishing the skulls of the two species.

Incisors small. I.' shorter, rounder, and less prominent than 

 in Macropus. I." and i.^ about equal in size, each with an in- 

 conspicuous notch near the centre of its outer edge. Canines 

 present, fairly well'-developed, apparently more or less functional. 

 Premolars large and heavy, p." enormously long antero-posteriorly, 

 generally exceeding in length the combined m.' and m.'", a well- 

 defined internal ledge running its whole length, and both its outer 

 and inner sides prominently grooved. Molars low, rounded, the 

 central antero-postcrior bridge almost or quite obsolete, and the
