MACRO PODI D/E. 
The length of the skull, according to Messrs. Quoy and 
Guimard’s Plate, is 3 inches and 4 lines. 
A skull of the M. hr achy {tr us, in the British Museum col¬ 
lection (see Plate 5, fig. 16), is remarkable for the shortness of 
the muzzle, which, though narrow in front, is broader behind 
than usual; the zygomatic arches are thrown boldly out¬ 
wards, and are very long, ns compared with other Kangaroos: 
the greatest breadth of the sknll is towards the posterior root 
of the zygomatic arches; the frontal bones are narrow; the 
nasal bones short, convex above, but little dilated behind, and 
with the sides very nearly straight. The foremost and hinder- 
most of the upper incisor teeth are about equal in width; the 
second incisor is narrower ; the third has a distinct notch at 
the apex, and situated rather behind the middle of the tooth 
(fig. 16tf of Plate 5); the premolar tooth has a greater 
transverse diameter than usual, and, indeed, is as broad as 
the first true molar, and its length is nearly the same. The 
true molars have the anterior ridge, and the small mesial 
ridge, very little developed.
