of its base a small cusp projects outwards, as in H. suillus. The 

 first premolar is scarcely equal to half the canine in vertical ex- 

 tent, hut is nearly equal to the second premolar ; the second molar 

 is equal to the first : but the third is very narrow, forming a simple 

 bony lamina as wide as the preceding molar, but less than half its 

 antero-posterior diameter. In the lower jaw the last molar is 

 smaller than the preceding one, but possesses the same number of 

 cusps ; the other molars and premolars present about the same rela- 

 tive proportions as in the upper jaw. 



On the whole the teeth are similar to those in H. harpia, agree- 

 ing in this respect with H. griseus and H. leucogaster, but differing 

 remarkably from H. suillus and H. auratus, in which the first upper 

 premolar is much smaller than the second, which equals the canine 

 in vertical extent.

(1876). 



Head, muzzle, and nostrils as in H. cyclotis ; ears also very similar 

 but larger, and near the base of the inner side of the ear-conch, 

 opposite the posterior angle of the eye, a small but distinct spur- 

 like process projects abruptly forwards from the convex margin 

 (Plate XVII. fig. 4, head, enlarged). 



Fur long and dense. Above brown, greyish at the base ; beneath, 

 the throat° chest, and abdomen are whitish, the sides of the body 

 light brown. Distribution of the fur as in H. cyclotis. 



Outer upper incisors longer than the inner ones ; first upper pre- 

 molar about three fourths the size of the second premolar, and ni a 

 plane slightly internal to the canine and second premolar; other 

 teeth as in H. cyclotis. . . ^, , . . 



This species resembles H. cyclotis m size, m the general form of 

 the ears, and in the distribution of the fur. It is easily distinguished, 

 however by the presence of the small projecting tooth on the inner 

 maro'in of the ear-conch, near its base, by the relatively small size 

 of the first upper premolar, and by the colour of the fur, which,
