The latter has a similar depressedwhorl section on the phragmocone, and comparable ornament consisting ofradially elongated umbilical tubercles, single, slightly concave ribs and promi-nent clavate ventrolateral tubercles. Through reduction of the umbilical width,crenulation of the keel, separation of the lateral keels into external tuberclesand splitting of the ventrolateral tubercles, Paratexanites australis
