the whorls become flattened and the ribs weakened in but is has an even more turriculate shell of 8° spiral angle D'ORBIGNY's species. and a smaller adult(?) size. In the slender shell form, the Hierlatz Alpe specimens Distribution — Hallstatt, Hierlatz Alpe, Late are similar also to Katosira carusensis (D'ORBIGNY, 1853), Sinemurian (Oxynotum Zone). Figure 84 — Pseudokatosira? aff. undulata (BENZ, 1832) (A-B, J-K), Pseudokatosira undulata (BENZ, 1832) (C-D) and Katosira periniana (D'ORBIGNY, 1853) (E-I). — 1 a-b: copy of the original "Chemnitiga undulata" figures from STOLICZKA (1861) Tafel I; A-B: peristomal view of Pseudokatosira? aff. undulata (BENZ, 1832) (GBa 2008/69/1/1) from the Hierlatz Alpe in apertural view, A = Xl, B = x2; C-D: Pseudokatosira undulata (BF.NZ, 1832) from the Bakony Mts (refiguration, HGM), xl; E-I: Katosira periniana (D'ORBIGNY, 1853), EF, H: refiguration of a specimen from Lókút, Kericser (Bakony Mts, HGM), V.—Y = xl, H =x3; G, 1: a juvenile specimen from the "originals collection" of STOLICZKA (1861) (GBa 2008/69/1/2/1), its dimensions suggest belonging to K. periniana, G = xl, I = x5.5; J-K: a juvenile specimen with protoconch from the "originals collecfion" K = xl, J = x7; the outline of the last whorls of this cyrtoconoidal shell(part) coiled in 10° spiral angle, which corresponds to that of the adult shell of Pseudokatosira? aff. undulata (BENZ, 1832); in the other characters, this juvenile shell well correlates with the comparable shell parts of Pseudokatosira undulata (BENZ, 1832) figured by NÜTZEL & GRÜNDEL (2007, pl. 1: 5 a—e), even the riblets of the protonch of the same type are obscurely visible.
