368 DR. ST. G. MIVART ON THE ARCTOIDEA. [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 Meles, 

 more quadrate and developed, with the anterior and posterior ex- 

 ternal cusps larger, the antero-internal cusp much more developed, 

 but no internal cingulum. The first true molar has its postero- 

 external 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 iuto two prominences, one in front of the 

 other. 



In 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 auteio-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 pre- 

 molar. 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 

 boue, and is flattened and grooved. 



Mydaus^. — 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,
