DENDROMYS TYPICUS 
Teeth, &c. — The incisors of the upper jaw are deeply grooved and their 
cutting edges slightly notched. The anterior portion of the first molar tooth 
is crowned with four robust, obtuse denticuli, the last third of the crown is flat 
and exhibits two small cup-shaped cavities ; the second tooth has the crown 
slightly concave, and marked with some small cup-shaped cavities ; the last 
is very small, somewhat cylindrical, and with the crown is flat. The first 
molar of the lower jaw is crowned with four robust obtuse points, two towards 
its outer and two towards its inner edge, the second has two points near to 
the anterior margin of the crown, the remaining portion of the latter is dis- 
tinctly concave ; the last molar has its crown occupied by two ill-defined points 
standing transversely. For views of the teeth, see Mammalia, Plate 21. Fig.

All the specimens of this little animal which have come under my observation were caught 
upon trees, shrubs, and vines, and many of them were procured in the immediate neighbour- 
hood of Cape Town. It is very active in its movements, and runs from branch to branch 
with great rapidity.
