IJospiriferina semicircularis (BÖSE, 1898) (Plate VIII: 23-25) — This species was described by BÖSE (1898) from the Schafberg fauna. Our specimens (2) represent a transversally less elongate variant showing the characteristic, almost straight, asymmetrically gently deflected anterior commissure. Unguithyris aspasia (ZlTTEL, 1869) (Plate VIII: 30-34) — This most characteristic Mediterranean species is copiously represented in our collected material (12 specimens). Many authors cited L, aspasia with MENEGHINI as author. However, MENEGHINI (1853) mentioned this species name only in a faunal list, therefore his record must be taken as nomen nudum. The first author to describe L, aspasia was ZlTTEL (1869). Securithyris adnethensis (SUESS, 1855) (Plate VIII: 38-42) — This species was collected in an outstanding number (116) and it seems to be a consequently dominant species of the Schafberg fauna: BÖSE (1898) found several hundred specimens. The large variation range gave a sound basis to BÖSE (1898) to synonymize the species adnethensis with adnethica SUESS, 1861. This was followed by RENZ (1932) with the inclusion of the widely used synonym erbaensis SUESS in PlCTET, 1867. The senior synonym adnethensis is the type species of the genus Securithyris VÖRÖS, 1983. Viallithyris gozzanensis (PARONA, 1880) (Plate VIII: 35-37) — The eight, mostly incomplete specimens show the characteristic, wide, well demarcated, straight sinus of the anterior commissure. This diagnostic Mediterranean species is the type of the genus Viallithyris VÖRÖS, 1978. Bakonyithyris ovimontana (BÖSE, 1898) (Plate VIII: 43-45) — This species is the second most frequent in our collected material (31 specimens). It stands close to B. pedemontana (PARONA, 1893) the type species of Bakonyithyris VÖRÖS, 1983, but differs in its usually larger size, the wider and fiat sinus of the anterior commissure, and the presence of a narrow, elongate sulcus on the umbonal part of the brachial valve. Zeilleria mutabilis (OPPEL, 1861) (Plate VIII: 46-48) — This very common and widespread Mediterranean Lower Jurassic species was found in eight specimens in the Pliensbachian red limestones of the Schafberg area. It is more frequent in the Sinemurian Hierlatz limestones; further comments on this species were given in the respective part of this paper.
