Teeth very acute, subulate, more or less compressed, cutting 
edges towards the tip. The teeth of the upper jaw are arranged 
in three rows, one row on each side and one short one on the palate. 
The posterior nasal and adjoining palatine tooth are longest of the 
series ; these with some neighbouring ones, also a few on the lower 
jaw, have an acute notch on the posterior edge, with a slight nasal 
lobe beneath it. Nasal teeth, and anterior mandibular teeth, con- 
siderably rounded towards the base. The teeth arranged along 
the sides of the upper jaw are in two rows of thirteen each, the 
first six on each side are equidistant and of equal size; then 
follow three pairs, and lastly a single one. The pairs and the 
single one are slightly more delicate in structure than those in 
front; all about an eighth of an inch in length. Nasal teeth about 
twelve, exclusive of about twelve very short ones alternating with 
them, but rather exterior to their bases, so that the mingled nasal 
teeth may be considered as making an approach to the biserial 
arrangement. Three teeth on the mesial line of the nasal disk 
long, slender, and very acute, the posterior pair being the longest in
