about 17 inch long, allowing for the part cut off and left in the skin. 
In an adult, therefore, their length would be rather more than two 
inches.

a, b, c, folds of the nasal cartilage; d, ligament. 
The whiskers are disposed in 5 rows, extending backwards from 
the nose, with a few straggling hairs between the lip and the first 
row. ‘There are 4 bristles in each row, so arranged that a bristle 
in any given row is set opposite to the interval between two bristles 
in the next. Those of the hind rows are much the longest. In the 
adult male the same arrangement obtains, as far as I can make out ; 
but several hairs have fallen out. They are stout, flattened, white 
bristles. The longest measures 8 inches. 
The ears are 13 inch long (fig. 6), slender in form, and recurved 
at the tips. Their great length in proportion to the body will be at 
once observed.

Teeth, in both specimens, I. =a C: — M. =5 =36. In the 
upper jaw, themolars (Plate LX XII. fig. 1) aresmall, conical, sharply 
pointed, with a small anterior cusp, which increases in size progres- 
sively from the first to the fourth. The fifth molar is much re- 
curved, and consists of a large anterior lobe with a very small 
posterior one. The last molar is simple, and recurved like the 
fourth. There is no “cingulum” on the external surface of the 
teeth ; but there is one, not very prominent, on the internal, termi- 
nating anteriorly in the small cusp before mentioned. There is 
rather a wider interval between the last two molars than between
