TUPAIA JAVANICA. 



The particulars which apply to the teeth of the three species hitherto dis- 

 covered, generally, are the following, as to number — 



Uppek Jaw — 2 front teeth, 21 canine teeth, 14 grinders. 

 Lower Jaw — 6 ditto 2 ditto 12 ditto. 



They have in the upper jaw no intermediate, but two large cylindiical, erect, 

 and rounded lateral front teeth, placed at the angle of the jaw; further — one canine 

 tooth on each side, which is smaller than the front tooth, very slightly curved 

 towards the point, and solitary, being placed at an equal distance from the other 

 teeth ; and seven grinders on each side, of which the three first are snaall, having a 

 single point, and the four posterior teeth compound, and marked with several sharp 

 elevated points on the surface. In the lower jaw they have individually six pro- 

 cumbent front teeth, of which the four intermediate teeth are very long, and the 

 outer one on each side very short ; further — one large canine tooth on each side, hav- 

 ing a broad base, and tending obliquely outward ; and six grinders, the two first of 

 which are small, and consist of a single point, while the four posterior teeth are com- 

 pound, having a broad crown, from which several sharp points project. 



For a distinct view of those characters, which are common to all species of 

 Tupaia, I refer to the Plate of Illustrations, in which Letters I, K, & L exhibit the 

 teeth of Tupaia Tana ; Letters M & N, those of Tupaia ferruginea ; and Letters 

 O, P, & Q, those of Tupaia javanica. 



I proceed, after these general remarks, to describe the Tvipaia javanica. The 

 Bangsuing has the appearance of a sprightly animal ; and as far as its manners are 

 known, it perfectly agrees with this character. Its body is graceful, and handsomely 

 formed, and its limbs are slender, and fitted for great agility : its size and exterior 

 habits so nearly resemble the individuals of that family which lUiger has deno- 

 minated animalia agilia, that, on a superficial view, it has been considered to belong 

 to it. Our animal agrees with one of the most numerous sections of this family, 

 the Squirrels, in the form of the body, the proportional length of the extremities, the 

 breadth of the tail, and the faculty of carrying it on the back as a plume ; but the 

 succeeding details wiU shew that its structure and organization are essentially 

 different. 



The head of the Tupaia javanica is oblong, rather depressed, and very gradually 

 attenuated to a conical muzzle, which is somewhat compressed laterally. The nose is 

 obtuse and naked. The nostrils are slightly curved, somewhat broader in the middle, 

 and pierced from the sides. The upper jaw surpasses the lower but little in length. 

 From the upper lip are protruded mustaches, consisting of numerous short, slender
