«Description: Shell very thin, equilateral, suborbicular. A single strong radial cord extends nearly to the bak anteriorly and another posteriorly; three weaker, equally spaced cords lie between the secondary cords and become obsolete 2 mm. from the margin of the disk. Fine, concentric lines extend straight across the radials. Submargins plain, narrow, steep. Auricles large, probably subequal, with about 7 fine, scabrous radial threads. Internal margin of the shell grooved for about 2 mm. Provinculum; auricular crura. Dimensions: height 14, width 13 mm. This species is named in honor of Dr. W. C. Mansfield of the United States Geological Survey.
Remarks: This species differs from P. leonensis Mansfield very markedly in sculpture. The grater portion of the disk of wendelli has only concentric sculpture of fine lines while the whole disk of leonensis has strong radial sculpture. The concentric lamellae are reflected away from the beak on the summits of the ribs of leonensis, while on wendelli the lines pass directly across the radials. The concentric sculpture of wendelli is much weaker and the shell is more nearly orbicular. Occurrence: Caloosahatchie Pliocene. Ft . Denaud, Fla. Holorype: A left valve. Collection H . I. Tucker.» HELEN lONE TUCKER-ROWLAND, 1934
