rather long, hut adpressed, and the hidden portion is almost hlack, narrowly tipped
with the reddishrbrown, the sides of the hair being blackish-brown. On the parachute,
only a few hairs have the reddish band, and these are most numerous towards
the margin. The tail is rather bushy and but slightly distichous, and the hidden
portion of its fur is pale fawn at the base, passing into pale chestnut-brown, washed
with duskydjrown on the sides and upper surface. The margins of the eyelids are
dark brown, and the sides of the face are pale rufous. The ears are moderately large
and rounded, rathe? dark brown towards the tips, and pencilled at the base, anteriorly
and posteriorly, with long delicate hairs. There are no true cheekdnistles, but the
moustachial hairs are very long. The under surface is pale ferruginous, palest
on the mesial line, and most rufeseent on the outer half of the membrane, the margin
of which inferiorly is pale-yellowish. The hairs on the membrane have dark slaty,
almost black bases, the ferruginous being confined to the tips. The fur of the under
parts is very soft and dense. The feet are well clad, more especially those of the
hind limbs. The tail is half the length of the body which attains to about 8 inches.
I t is distinguished from P. alboniger by its more rufeseent colouring and by the
pencilling of its ears.
I t oecurs in Sikkim and Upper Assam, from whence Blyth first obtained it.
Mr. Bonynage, who presented the typical specimens to the Asiatic Society of Bengal,
also gave one to Mr. Walker, who referred it to P. sagitta. As already stated, I
obtained two specimens of this species at Teng-yue-chow.
The type of P. kaleensis, Swinhoe, from Eormosa is in the British Museum, and
it agrees exactly in its colour and in the pencilling of its ears with this species, of
which I believe it to be an example.
Dr. Gray described this flying squirrel as about one-third smaller in length and
breadth than P . caniceps, of which he was at first inclined to regard it as the young,
but he afterwards states that the bones of the typical specimen show no indication
of youth. The type was procured at Darjeeling. Tenuninck also lays stress on the
fine silky tufts at the base of the ears, by which he states it is distinguished from
its congeners. He procured it in the Island of Sumatra.
I have examined the type of P. setosus, which agrees with P . pectrsonn in the
absence of eheek-bristles and in its general characters, but the specimen is not fully
grown, measuring only, along the back to the root of the tail, A 75,-and the tail S'75.
I t is less rufeseent than the adult, and the under parts are whiter, as are also
the cheeks.

This is a medium-sized squirrel, about the dimensions of P. jmbriatw . I t
has a long pencil of blackish hairs at the base of the posterior margin of the ear
and at the external surface of the upper angle. The cheek-bristles are well
developed. The eats are moderately large, but not broad, and With their posterior
borders slightly concave and the tip rounded. Around the eyes is blackish, and
before the ears y ello wish- grey, and the cheeks, are white, washed with yellowish.
The fur generally is very soft and dense, and two-thirds of its base is dusky ashy,
the remainder being reddish-brown with a black tip. On the vertex, the sub-apical
brown is paler than on the rest of the body, and the parachute is dark brown
above, washed with pale brown and having a pale yellowish edge. The under
surface of the membrane is very sparsely covered with fine, white hairs, and the
lower parts of the animal and inside of the limbs are white, washed with yellowish.
The feet are pale yellowish-brown. The tail is very bushy, and not distichous
in the adult, but Blyth mentions that it is so in the young, but not markedly so.
I t is sometimes yellowish-brown, passing in others into dusky brown, especially
on its latter half, the mesial line being dark brown. Its under surface at the
basé is pale brown, passing into blackish-brówn beyond.
This species was originally described by Biyth from a half-grown specimen in
rather abraded pelage, and the condition of the type led him to apply to it a not
very appropriate name.
The skull reveals the species tó be allied tó P. phoeôiïielaèi ànd this not Only in
size and form, but in the character of its teeth, which present tó á slight extent
the ridging which distinguishes the teeth of that species. I t differs, however,
from it in many important characters, and the two forms constitute two well-defined
species. On the other hand, it is more nearly related in its external characters to
P . fmbriatus, from which, however, it is recognised by its pencilling of the ears
at their bases; while from P . villoms, which also presents this latter Character
and is a closely affined species, it is distinguished by its larger size, bushy tañ, and
much less vivid colouring.

This is a squirrel about the size of P. fmbriaius, and, like P . fuscocapillus
and P. pearsonii, it has a long pencil of fine hairs before and below the ears, and
its tarsus is clad as in P . meîanopierus.
In colour it is rufous, almost orange-brown, which is most intense on the limbs,
on the middle of the back, on the front of the face, and on the cheeks. The hairs
of the back and occiput are terminated more or less by yellow points which rest
on a basal ground of slaty. The area around thé eyes and the muzzle is brown,
