narrow chambers separated by thick septa. Margin slightly thickened. At the centre there is a knob only faintly protruding, a feature different from the form recorded by KAASSCHIETER (1961) having a more accentuated umbilical knob. In Hungary, it is known from the beds taken for Lower Eocene of the Dorog Basin. Lower and Upper Eocene of England, the Cuisian and Lutetian of France, and the entire Eocene of Belgium. Gen.

A few specimens occur in both the Assilina spira and the Nummulites perforatus horizons. Middle-size test. The slightly convex spiral side coarsely, the conical umbilical side finely perforate. Test-wall bearing a longitudinal furrow at the last chamber. Chambers slightly thickened at the periphery. New for Hungary. Cuisian and Lutetian of France, Belgium and the Netherlands. Gen.

XIV, fig. 1\ Relatively thick-walled, flattened test, strongly perforate along the chamber sutures, finely perforate at the other surfaces. Well identifiable with Planulina burlingtonensis var. neelyi, notwithstanding some differences in the pattern of perforation. Fairly common in the lower part of the Assilina spira horizon. A few specimens occur in the JV. perforatus horizon, too. Lower and Middle Eocene of Europe; common in the Lower.
