width. Behind the nasals, the skuD is concave from before backwards, and the 

 frontals are rather swollen. 



The upper margin of the orbit is directed inwards as far as the supra-orbital 

 foramen, from whence it passes outwards and downwards. The lachrymal notch 

 is well marked, and the malar perforation large.

The most particular feature in the dentition of this species is the close prox- 

 imity of the canine to the 1st premolar, the two teeth being placed side by side 

 without any appreciable interval. The 1st premolar is little more than one-half the 

 size of the canine. The 2nd premolar has no internal cusp, but has an anterior one 

 feebly developed. The 3rd premolar is as in the other species. The posterior internal 

 cusp of the molars is only indicated by a faint swelling on the first molar, the 

 others showing no trace of it. The canine of the mandible is not so procumbent as 

 in the other species, and is much higher than any of the surrounding teeth, T. 

 belcmgeri resembles it somewhat in this character. 



The two specimens from which the foregoing description is taken were procured 

 at Malacca and referred by Blyth to T. javanica, but it is imjDossible to reconcile 

 their short, round skulls with Horsfield's figm'es of the head, nor with the drawing 

 of the skull of that species given by Miiller and Schlegel. 



The figure given by P. Cuvier of the Cerp or Banxring as T. javanica agrees so 

 closely with the specimens before me in its coloration, short muzzle, and long tail, 

 that I am disposed to refer it to the present species, as it is apparently not T. fer- 

 ruginea.
