Original diagnose after Leidy (1877) p. 250: Among the fish teeth occurring in collections of fossils from the Ashley phosphate beds, I have noticed a number which appear to pertain to a species of Ray. Teeth of the kind are 1•epresented in figures 10-1:3, Plate xxxiv., twice the natural size. They may perhaps be symphysial teeth of a Shark. The crown of these teeth is usually wider than high, and the base is extended downward at the middle in a rounded prominence, and backward posteriorly in a similar prominence. The summit rises in a tapering point, and the lateral acute borders exhibit seven or eight denticles successively decreasing towards the base. The teeth of figures 10, 11, have the main point worn off and the lateral denticles more or less abraded. The tooth of figure 12 has the main point partially worn off; and even that of fig. 13 has the extreme point somewhat blunted by abrasion. The root of these teeth is a shallow basis with a trilateral outline, the angles rounded and the lateral ones slightly projecting.
