of Vetters' figures nearly all the ammonites seem best compared with
Franconian forms from the Neuburg Beds, figured by Schneid. For
instance the ribbing of Vetters' pi. xxi, fig. 2, is identical with that of
Anavirgatites franconicus Schneid sp. (1915, p. xi, 3), and Vetters' pi. xxii,
fig. 5, could well be a worn cast of ? Wheatleyites racemosus Schneid sp.
(1915, pi. ix, fig. 1); and Vetters' pi. xii, fig. 7, assigned by Spath with a
query to Pectinatites, might belong to that genus or still more to Sublithacoceras
cf. penicillatus or callodiscus Schneid spp. (1915, pi. iii, fig. 3,

pi. iv, fig. 2). Perisphinctes reniformis Vetters (pi. xxii, fig. 6) remains
problematic but suggests an early Virgatosphinctes like V. eystettensis
Schneid sp. (1914, pi. iii, fig. 5) from the Lithographicum Zone.
Thus the balance of probability (so far as present knowledge goes)
is in favour of an approximate correlation between the Klentnitz Beds
and the Neuburg Beds of Bavaria and the Pectinatus Zone of England
(see Arkell, 1946, pp. 22-3). It remains, however, an awkward fact that
the index fossil of the Klentnitz Beds, Pseudovirgatites scruposus, has been
found neither at Neuburg nor in the Neuburg fauna at Saint-Concors;
in fact, nowhere else in the world except Stramberg.
The Ernstbrunn Limestone, which in general overlies the Klentnitz
Beds, presents yet another problem. The fauna has been called a mixture
of those of Stramberg and Kelheim (Abel, 1899, p. 376). The ammonites
borrowed from Vienna by Spath (1933, pp. 847-8) consist (besides a few
