and lower edge sharp ; they are almost horizontal in their 
direction, being hut slightly curved upwards. Next follows, 
on each side, a series of four small premolars, the hindermost 
of which has two fangs, whilst the others appear to have hut 
one. The true molars nearly resemble those of the upper 
jaw, though they are narrower and larger. The first lias a 
large irregular anterior lobe, which is more elevated than any 
other part of the tooth, and is divided into two tubercles: 
the three posterior molars have each four tubercles. The 
space occupied by the true molars is relatively much less in 
B elide us than in Petaurista.
