POLAND<br />

monographed by Neumayr (1871), has a 'mixed' aspect. Teisseyre<br />

(1887), who first described the genus Proplanulites from the Balin Oolite,<br />

handled over 10,000 arnmonites from it, but saw only two specimens of<br />

Lytoceras and none of Phylloceras. The following is a list of the ammonites<br />

figured in Neumayr's classic monograph, embodying numerous subsequent<br />

changes of nomenclature.<br />

Hecticoceras laubei (Neum.), pi. ix, fig. 4<br />

Hecticoceras krakoviensis (Neum.), fig. 5<br />

Hecticoceras balinense Bonarelli, fig. 6<br />

Hecticoceras taeniolatum Bonarelli, fig. 7<br />

Hecticoceras metomphalum Bonarelli, fig. 8<br />

Torricellites uhligi (Parona & Bonarelli), fig. 9<br />

Procerites sp., pi. x, fig. 1, pi. xi, fig. 1<br />

? Orionoides sp., pi. x, figs. 2, 3<br />

Proplanulites majesticus Buckman, pi. xi, fig. 2<br />

Proplanulites sp., fig. 3<br />

Proplanulites cf. spirorbis (Neum.), fig. 4<br />

Subgrossouvria euryptycha (Neum.), pi. xii, fig. 1<br />

Grossouvria anomala Loczy, fig. 2<br />

Siemiradzkia de mariae (Parona & Bonarelli), fig. 4<br />

Choffatia evoluta (Neum.), fig. 2<br />

Grossouvria subtilis (Neum.), fig. 3<br />

Choffatia furcula (Neum.), pi. xv, fig. 1<br />

Choffatia balinensis (Neum.), fig. 2<br />

Parapatoceras calloviense (Morris), p. 46<br />

In the Cracow area conglomerates in the Callovian contain pebbles<br />

derived from Palaeozoic rocks and in at least one locality a 0-4 m. marl<br />

belonging to the Lamberti Zone rests directly on Upper Carboniferous<br />

porphyry (Dzulynski, 1952, p. 168). In the hills SW. of the Lysa<br />

Gora, however, the Callovian reaches a thickness of about 33 m. It<br />

consists of sandy marls with subordinate bands of limestone, partly<br />

silicified, and chert, and yields Macrocephalites, Reineckeia and Erymnoceras<br />

(Swidzinski, 1931, p. 851).<br />

Very different is the facies to the north-east, where at Lukow, 65<br />

miles ESE. of Warsaw, a brickfield is worked in an erratic mass of<br />

unstratified clay 4 m. thick, containing nodules with splendidly preserved<br />

ammonites mainly of the Upper Callovian (Makowski, 1952). A few<br />

nodules found in a separate part of the workings yield only Cadoceras<br />

tschefkini (d'Orb.), gen. nov. (aff. Longaeviceras) sp. nov. (Makowski,<br />

pi. vi, figs. 1-3), and schumarovi (Nik.) (pi. v, 10); the age of these is<br />

probably Athleta Zone or Middle Callovian. All the other ammonites<br />
