animals, and are indeed reported to be nore carnivorously inclined than any of the 
other members of the family. They frequent only forests containing large trees, 
and pass from the boughs of one tree to another after the manner of squirrels, 
sometimes swinging themselves by the tail in order to reach a branch which would 
otherwise be inaccessible. There are four teats in the pouch of the female, which 
usually contains from two to four young; and it is said that a female is never 
killed without at least one being in the pouch. So tightly do the young adhere 
to the nipples, that they cannot be torn away without causing blood to flow. 
The True The true phalangers (Z’richosurus), of which there are two 
Phalangers. species, from Australia and Tasmania, where, in common with the 
members of the next genus, they are called opossums, are reacily distinguished from 
the cuscuses by the character of their tails. Thus, instead of being tapering and 
naked for about half its length, this appendage is thickly covered with bushy hair 
up to its very tip, which, together with a narrow line on the lower surface extending 
about a third of the length, is alone naked. The ears are more or less hairy behind ; 
and there is also hair on the hind-feet behind the heel. The relative lengths 
of the toes of the fore-feet are somewhat different from those obtaining in the 
cuscuses; and there is also a gland on the chest not found in the latter. The 
common phalanger (Z’richoswrus vulpecula) is one of the most abundant animals 
in Australia, where it is found everywhere in forest-regions, with the excep- 
tion of the Cape York peninsula; it is represented by a variety in Tasmania. 
Deriving its specific name from its general resemblance in size and form to a 
small fox, it is especially characterised by its comparatively long and narrow 
ears, in which the length considerably exceeds the width. In the ordinary form 
the general colour of the soft and close fur is grey above and yellowish white 
beneath; the ears being white, and the tail black. In the larger and stouter-built 
Tasmanian variety the fur is longer, and of a more decided brown or rufous colour, 
with little or no white on the ears. The short-eared phalanger (7. caninus), of 
Queensland and New South Wales, comes very close to the latter variety, from 
which it differs by its short and rounded ears. 
While the common phalanger inhabits forests, the short-eared species 
frequents scrub-jungle; but in other respects the habits of the two are prob- 
ably very similar, both being purely nocturnal creatures. During the daytime 
the common species lies securely curled up in some hole in a giant gum-tree, but 
soon after sundown issues forth to prowl in search of food, and remains abroad 
until the laughing jackass commences its morning notes. Leaves—especially 
those of the peppermint-gum—constitute their chief food; but their diet is 
occasionally varied with the flesh of a bird. In their movements among the 
forest trees they are very nimble; and they are much aided in their evolutions 
by their highly prehensile tails. They utter, especially during the pairing- 
season, a loud, chattering ery, which echoes far through the forest. stillness. 
The female phalanger gives birth to one or two young, which are retained for a 
long period in the pouch, but afterwards cling to the back of their parent till able
