The vertebra are—cervical, 7 ; dorsal, 13 ; lumbar, 6 ; sacral, 1*; 
caudal, 23. 
With regard to the dentition I need only remark, that the hinder- 
most incisor, on either side of the upper jaw, is separated 
from the preceding one by a very narrow space only (a space 
about equal to its own diameter) ; the canine teeth are larger 
than usual, sometimes being nearly half an inch in length ; 
the molar teeth have the transverse diameter greater than in 
other species of Perameles , and these teeth are not expanded 
on the outer side : the last molar is of the same form as the 
others, but of smaller size. 
Section 2. Perameles proper. 
Feet, tail, and ears, proportionately short; the hind foot with a 
rudimentary inner toe, naked beneath in front, and at the 
heel. Fur distinctly composed of hairs of two kinds, the 
one forming a soft under fur, the other hairs coarse, flattened, 
and longitudinally grooved. Tail clothed with very short 
adpressed hairs only. Pouch opening backwards. 
* But one vertebra joins the os innominatum, and none of the vertebra in 
the sacral region are anchylosed.
