Description
Original description of Woodward, 1889 [2593]:
Type. Teeth shown in PI. V. figs. 4-6. Teeth very similar to those of P. polygyrus, but having the transverse ridges upon the crown relatively much more delicate and numerous.
Form. & Loc. Turonian and Senonian: S.E. England.
P. 8881. Group of ten naturally associated teeth of the lower jaw, forming the type-specimen. PI. V. fig. 4 represent a median tooth inadvertently placed with the anterior border upwards; fig. 5 a first lateral; and fig. 6 an outer series; Kent.
