nged, and the feet well developed and
broad_. The first group has also a division or bare area on the
vertex; the second has not.

FAMILY HYLOMIDAE (_Anderson_).

The following little animal has affinities to both _Erinaceidae_ and
_Tupaiidae_, and therefore it may appropriately be placed here. Dr.
Anderson on the above ground has placed it in a separate family,
otherwise it is generally classed with the _Erinaceidae_. Its skull
has the general form of the skull of _Tupaia_, but in its imperfect
orbit, in the rudiment of a post-orbital process, and in the absence
of any imperfections of the zygomatic arch and in the position of
the lachrymal foramen it resembles the skull of _Erinaceus_. The
teeth are 44 in number: Inc., 3--3/3--3; can., 1--1/1--1; premolars,
4--4/4--4; molars, 3--3/3--3, and partake of the character of both
_Tupaia_ and _Erinaceus_. The shank-bones being united and the
rudimentary tail create an affinity to the latter, whilst its
arboreal habits are those of the former.

_GENUS HYLOMYS_.

Head elongate; ears round; feet arboreal, naked below; tail
semi-nude; pelage not spiny.

NO. 157. HYLOMYS PEGUENSIS.
_The Short-tailed Tree-Shrew_.

HABITAT.--Burmah, Pegu, Ponsee in the Kakhyen hills.

Appears to be identical with the species from Borneo (_H. suillus_).

FAMILY TUPAIIDAE.

These interesting little animals were first accurately described
about the year 1820, though, as I have before stated, it was noticed
in the papers connected with Captain Cook's voyages, but was then
supposed to be a squirrel. Sir T. Stamford Raffles writes: "This
singular little animal was first observed tame in the house of a
gentleman at Penang, and afterwards found wild at Singapore in the
woods near Bencoolen, where it lives on the fruit of the kayogadis,
&c." Another species, _T. Javanica_, had, however, been discovered
in Java fourteen years before, but not published till 1821. They are
sprightly little creatures, easily tamed, and, not being purely
insectivorous, are not difficult to feed in captivity. Sir T. S.
Raffles describes one that roamed freely all over the house,
presenting himself regularly at meal-times for milk and fruit. Dr.
Sal. Muller describes the other species (_T. Javanica_) as a
confiding, simple little animal, always in motion, seeking its food
at one time amongst dry leaves and moss on the ground, and again on
the stems and branches of trees, poking its nose into every crevice.
