Remarks: V . manuelensis n. sp., differs from V . multicamerata de Klasz in its abruptly flaring, sub circular test and smaller number of chambers in the multiserial portion. V . manuelensis differs from other species of Ventilabrella in its abruptly flaring, sub-circular test, diminished biserial portion, larger number of chambers, and heavy vermicular ornamentation.
Range: G . fornicata-stuartiformis Assemblage Zone, G. elevata Subzone (G. calcarata Zonule) to R. subcircumnodifer Subzone (R. subpennyi Zonule) possibly higher.
Occurrence: In Mexico, V. manuelensis is abundant in the late Campanian and early Maestrichtian portions of the Mendez Shale (MX 13, MX 15 of Pessagno, see appendix).
V. manuelensis occurs in late Campanian sediments of the Blake Bahama Basin, Joides Leg 1 (1/4A/1/2, see appendix); in late Campanian sediments of the Rio Grande Rise, Joides Leg 111 (3/21/5/5, see appendix); and in late Campanian and early Maestrichtian sediments of Orphan Knoll, Joides Leg XII (12/11IA/11/6 to 1211IlAIll/5, see appendix).
V. manuelensis was found in one late Maestrichtian sample from the Mendez Shale ( M X 80 of Pessagno, see appendix), and in late Maestrichtian samples from Joides Leg XI1 (12/111A/11/1, see appendix), both of which contain reworked late Campanian and early Maestrichtian species.
