Teeth slender, those anteriorly placed being much curved and 
attaining a total height of about 0-025 ; branches of the root short. 
Outer coronal face prominently convex ; inner face smooth ; lateral 
denticles long, slender, and pointed, in two or more pairs, the inner

Type. Detached teeth. 
Teeth robust, attaining a maximum total height of about 0'04 ; 
apex of crown only slightly bent inwards, except in the most ante- 
rior pair; outer coronal face gently convex; inner coronal face 
strongly convex, flattened in the middle, smooth. Branches of the 
root of moderate length, coni[iressed ; considerably divergent in the 
most anterior teeth. 
As remarked by Agassiz, the detachefl crowns of the teeth of this 
species can scarcely be distinguished from those of Oxyrhinadesorii.
