Taxonomy
Original description: Translated from Italian: "Shell of scaphoid shape, early chambers coiled trochospiral and later become planispiral, peripheral margin wide and rounded, chambers regularly increasing in size, wide, low and a little convex, radial sutures, straight, weakly depressed; Last chamber somewhat convex, aperture semilunar and wide opening in front of the last chamber. Biumbilicate, coiling moderately involute with the external chambers that cover part of the internal ones. Shell with particularly coarse pores, so that the appearance is very rough. Number of final whorl chambers 9-10."
