|---|---|---|
| H. J. Finlay 1939 | Shell very close to P. floridana Cushman from the Micoene of Florida (see for example U.S. Geol. Surv., Prof. Paper 175A, p. 22, pl. 7, fig. 11, 1933) and evidently representing that species in New Zealand. There are the same doubly sigmoid suture lines, high and broken medially, but flattening to almost horizontal at sides. There is the same narrowly elongate shell, oblong in section, with three keels forming each edge. The shape is slightly different, the New Zealand shell having a slightly smaller angle of expansion, especially in the later half where the sides tend to become subparallel. The most striking difference is in the sculpture; in floridana there is a single very short median costa over the first few chambers; in parri, though occasionally the shell is almost smooth, there are normally two costae, a little weaker than the keels and equally dividing the area between them, running more than halfway up the shell, occasionally with traces of a third.
