1		-The species is founded on a single lateral tooth from the upper jaw.
2		-The length is about 13 mm., the height from the lower margin of the root
3		-to the tip of the principal cone is about 7 mm.., and the height of the princi-
4		-pal cone above the root is about 4 mm.
5		-\\The principal cone is preceded by a group of 3 or 4 denticles, the first
6		-of Which is comparativcly large, but. all decrease rapidly in size as they ap-
7		-proach the root, giving somewhat the effect of a miniature cockscom'b.
8		-\\The principal cone is followed by four accessory cones which are all the
9		-same size, and a fifth accessory cone which is very small. There is an in-
10		-dication of a denticle at the extreme posterior end.
11		-\\The cutting edges of the tooth are entire, and are so thin as to be almost translucent.
12		-\\The tooth is similarly convex on both the inner and outer sides, and is
13		-well compressed.
14		-\\The root is straight on the outer side, convcx on the inner, with the base
15		-tapering to a thickness about equal to that at. the base of the crown, so
16		-that in profile the root is roughly the shape of a half circle.
17		-\\The tooth as a whole is very slightly twisted, but the concs and dcnticles
18		-are set straight on the root, and are not at all sigmoid.
