GRKAT KANGAROO. 
69 
incisor tooth on each side of the upper jaw (PI. 5, tigs. 1 and 2,) 
is longer from front to back in this species than in others 
which I have had an opportunity of examining 1 , and 1ms two 
external vertical grooves, one situated rather in front of the 
middle, and the second placed between this and the anterior 
margin. The size and proportions of the cranium are ex¬ 
pressed in the subjoined dimensions.
