One of the specimens figured by De Grossouvre (1894, pi. 12 (fig. 1)), from the Craie de Villedieu of Touraine, lacks the typical broad lateral ornament and may possibly be a transition towards P. (P.) subtricarinatum. P. westphalicum var. italicum Desio (1920: 216, pi. 16 (fig. 4)) lacks the bul- lae of typical P. (P.) westphalicum and has, instead, sharp-crested, narrow, widely spaced lateral ribs. In this respect it bears resemblance to P. stefaninii.
