Diagnosis
ReferenceDiagnosis
W. Blow 1967The small test consists of about 11 chambers arranged in a low trochospire with 4 1/2 chambers comprising the last whorl. The chambers are slightly to moderately inflated, closely appressed but separated by deeply incised ventral intercameral sutures. The intercameral sutures are marked by radial bands of less coarsely perforate wall and are distinctly “U”-shaped. The distinct ventral intercameral sutures are formed by a sharp “in-turning” of the chamber walls and this “in-turning” gives a moderately lobate appearance to the equatorial profile of the test. The umbilicus is small, but deep and open and is surrounded by an imperforate area which grades into the imperforate lip of the final chamber. The aperture of the final chamber is a low arch, somewhat asymmetrically placed with respect to the umbilicus. On the dorsal side the intercameral sutures are less deeply incised, less “U-shaped” than on the ventral side. The spire is low, depressed and the early chambers indistinctly separated one from the other. The wall is relativey densely perforate and the pores open into distinct pits between small rugosities. Wall calcareous, radial hyaline. Maximum diameter of holotype 0.27 mm.
