POUCHED MICE. 273 
animal than the last,-with short and coarse fur. The general colour of the upper-parts 
is pale grizzled grey, while the chin is white, and the lower surface of the body 
pale grey or white. The head is characterised by the large size of the ears, and the 
presence of a more or less indistinct black streak down the nose. These pretty little 
animals are arboreal and insectivorous in their habits; and appear to fill the place in 
Australia occupied in the Oriental region by the placental tree-shrews, which they 
much resemble in general habits. All seek their insect-prey by climbing the boughs 
of trees; and at least some make nests in the hollows of the trunks and branches. 
Common The tiny creature, known as the common pouched-mouse (Smin- 
Pouched-Mouse. ¢thopsis murina), constitutes, with three other nearly-allied species, a 
distinct genus, ditfering from the last by the extreme narrowness of the hind-foot, 
and also by the circumstance that the soles of the feet are covered with hair or 
granulated. This species measures 3} inches in length to the root of the tail; the

length of the tail being a little less than 3 inches. The pouched-mice of this genus 
are confined to Australia and Tasmania; and since they are terrestrial and insectiv- 
orous, they may be compared to the shrews among placental mammals. In all 
the pouch is well-developed ; and the number of teats varies from eight to ten. 
Jerboa The last and apparently the rarest of the typical section of the 
Pouched-Mouse. family is the jerboa pouched-mouse (Antechinomys laniger), from 
South Queensland and New South Wales, which constitutes a genus by itself. 
This little creature, which has much the appearance of a sharp-nosed jerboa, with 
very large oval ears, and a long tail, becoming bushy at the end, is distinguished 
from the members of the preceding genus by the great elongation of the hind- 
limbs, and the total absence of the first toe from the hind-foot. Its form is very 
slender and graceful; and the soft and fine fur composed almost entirely of under- 
fur. The general colour is pale grizzled grey, with the chin and feet pure white, 
and the hairs of the under-parts grey at the base and white at the tips. The tail, 
of which the length considerably exceeds that of the head and body, is fawn-
