«SPEC. CHAR. Suborbicular, wider than long, ornamented with thirteen broad flat elevated rays, concentrically striated; one valve nearly flat, concave near the beak; ears equal, square.
SIMILAR in size and shape to P. maximus, but distinct, the rays being flat, with nearly perpendicular sides; the two lateral rays are blended with many striae upon the sides of the valve. The two valves have not, that I know of, been discovered in contact: we are therefore unacquainted with its particular characters; the flatter one is less convex than that of either P. grandis or P. maximus. Our intelligent friend Mrs. Murchison has obtained several valves of this species from the Crag at Aldborough, and near Ipswich. It is also in the cabinet of the Rev. Mr. Leathes; but it is by no means so common as the grandis. Besides the two species just described, there are found in the Crag, P. maximus and P. Jacobaeus: but I have only seen fragments; and these are so identical with the recent species, that there is hardly any necessity for figuring them.» JAMES DE CARLE SOWERBY, 1828
