is formed the extremity of which is produced into an angle; the point of the angle is directed backwards The 
portion of the tail which is thus protected beneath, is well clothed with fur above, but the hairs arc not long, 
and the apical portion (which is cylindrical) is much less bushy thau in the large flying squirrels constituting 
the genus Pteron,y* The hinder feet have the heel clothed with fur, but the outer margin beneath is naked, 
and not densely clothed, as in Ptervmys. The lateral flying membrane extends from the wnst to the ankle, 
and is supported moreover by a long cartilage in front, as in Flora,,,,,* ; but this cartilage has its origin at the 
elbow-joint and not at the wrist, as in the genus just mentioned. The mterfemoral membrane extends to the 
heel and is moreover attached to the sides of the tail, and when expanded forms almost a straight line. 
’ “ In the structure of the skull Anomaluru* differs considerably from the known species of Sctunda. All 
the species of the family, the skulls of which I have had an opportunity of examining (and they are numerous, 
embracing all the known genera and subgenera), are distinguishable by the possession of a distinct post-orbital 
process to the cranium; they have the palate broad, and terminating in a line with the posterior molars, or 
behind that line; the molars of opposite sides of the jaw are parallel, and the ant-orbital opening is small, 
in the form of a tube, and serves only for the transmission of the infra-orbital nerve. These characters are not 
found in Anomaluru* • the post-orbital process is here reduced to a mere rudiment, being represented by an 
indistinct projection forming an obtuse angle: the ant-orbital opening is large, and evidently affords a passage 
for a portion of the masseter muscle as well as the nerve; it moreover opens directly m the bony plate which 
constitutes the anterior root of the zygomatic arch, and is not produced as it were into a tube as in the typical 
Sauirrels The palate is narrow, and has a deep triangular cmargination behind, the apex of the triangle being 
on a line with the hinder margin of the penultimate molar. The molar teeth converge in front, so that the 
space between the two foremost is scarcely equal in width to one of these teeth; the crowns ot the molars of 
opposite sides of the upper jaw, instead of being on the same plane, or very nearly so, are directed obliquely 
outwards; and the masticating surface of those of the lower jaw, to meet them incline m an opposite direction. 
The incisive foramina are longer than is usual in the Sctunda, and encroach in a slight degree upon the 
maxillary bones. The nasal portion of the skull is narrower, and the nasal bones are remarkable for a deep 
cmargination in front. 
The apparatus of scales was used by the animal to support itself when resting on the trees, 
which it ascends with great agility. I have observed this animal dart from the top ot a lofty tree 
to another at a considerable distance. Descending at an angle, it aimed with great meet) at the 
trunk of the tree on which it intended to alight, and, settling near the base, it would again ascend 
to travel to a third tree in the same manner; occasionally, when high up on the trunk, it wouk 
rest itself, making use of the singular apparatus of scales on the under side of the tail. I he 
unarmed portion of the tail was then turned backwards and upwards.
