assemblage of the Cordatum Zone in one of the thin limestones at
Monte Inici:—
CALLOVIAN
Calliphylloceras benacense (Gem.)
Phylloceras spp. indet.
Sowerbyceras tortisulcatum (d'Orb.)
Lytoceras sp. indet.
Lissoceras erato (d'Orb.)
Taramelliceras sp. indet.
Euaspidoceras aff. babeanum (d'Orb.)
Peltoceratoides cf. williamsoni (Phillips)
Perisphinctes cf. bernensis de Loriol
Perisphinctes cf. alligatus (Leckenby)
Perisphinctes (Dichotomosphinctes, etc.) spp. indet.
At Rocca che Parra, Calatafimi, Mr Warman found two separate
Callovian horizons. The upper held Indosphinctes cf. patina (Neumayr:
cf. Corroy, 1932, pi. xii, 3), Hecticoceras cf. metomphalum Bonarelli,
Ptychophylloceras cf. euphyllum (Neumayr) and Holcophylloceras sp.,
an assemblage which may belong to the early Middle Callovian, as does
perhaps a Hecticoceras figured by Floridia (1931, pi. v, 2).
A few feet lower at the same place he obtained the following
assemblage:—
Phylloceras cf. kudernatschi (Hauer)
Calliphylloceras disputabile (Zittel)?
Ptychophylloceras euphyllum (Neumayr)
Lytoceras adeloides (Kudernatsch)
Choffatia subbakeriae (d'Orb.)
Choffatia sp. indet.
Reineckeia rehmanni (Oppel)
Reineckeia (Kellawaysites) paronai Petitclerc
Reineckeia sp. indet.
Bullatimorphites aff. bullatus (d'Orb.)
Macrocephalites aff. macrocephalus Zittel
This is evidently a condensed bed representing the Lower Callovian and
also a basal part of the Anceps Zone. The Bullatimorphites is the form
already figured with Macrocephalites by Floridia (1931, pi. iv, fig. 1)
from Monte Inici. It is very like the typical Bathonian bullatus, but
similar forms range up into the Callovian in France. Several other species
of Bullatimorphites were figured from this condensed assemblage at Rocca
che Parra by Gemmellaro (1872-82, pis. i-v), as well as Macrocephalites,
Paralcidia, Choffatia spp. and Reineckeia segestana Gem. sp. (1868-76,
pi. viii, figs. 1-3).
