[Apr. 21, process is not so long as in Meles, and the zygomata are not so arched outwards; the skull has no such produced sagittal ridge, but is more flattened and much more broadened out posteriorly, like that of some aquatic forms. The muzzle is also shorter. The malar develops a distinct postorbital process, and that of the frontal is at least as marked. The infraorbital process is still very large. There is no subangular process. Molar formula, P. |» M . \. The upper incisors stand almost on a straight line, so slight is the curvature of their range. The first upper premolar seems to be always absent very early, and the first lower are generally so. The first upper molar, instead of greatly preponderating over the fourth upper premolar, is of about the same size. Compared with the teeth of Meles, the third upper premolar is larger, and the first molar smaller. The fourth upper premolar is, like that of Metes, more quadrate and developed, with the anterior and posterior external cusps larger, the antero-internal cusp much more developed, but no internal cingulum. The first true molar has its posteroexternal angle atrophied (compared with that of Meles), while it develops inwards somewhat posteriorly. It has the same essential pattern on its grinding surface, but the cusps are reduced so as to form as it were only a crumpled superficial irregularity, something like that of the third upper true molar of Ailuropus, with its postero-external angle obliquely cut away. There is really both a small external and a large internal cingulum, and also two minute external cusps (within the external cingulum), an internal cusp (enclosed by the internal cingulum), and the median prominence of Meles, here subdivided into two prominences, one in front of the other. Iu the lower jaw, the second and third premolars are as in Meles. The fourth is peculiar, and consists of three cusps, whereof the first and second are very light, and form a sectorial blade to fit against the front part of the fourth upper premolar. Behind these is a small, low cusp. The first molar is very like the corresponding tooth of the Civet, but the antero-external cusp is higher, and the talon larger, supporting five minute tubercles. The anterior sectorial part bites against the hinder part of the fourth upper premolar. The second molar is small, rounded, and quadricuspidate. The bone of the penis is four inches long ; one end of it has the form of a club, the other is bent at right angles to the shaft of the bone, and is flattened and grooved. Mydaus1.-The Teledu, a small burrowing Badger, of Java and Sumatra, is found at an elevation of 7000 feet or more, and is but about one third of the size of the Common Badger. There is but one true species of the genus. It has an elongated movable snout, 1 See Horsfield, Zool. Research, n. 2; F.
