Notes on the systematics, morphology and biostratigraphy of fossil holoplanktonic Mollusca, 1. Holoplanktonic molluscs from the Miocene of Wadi Gharandel, Western Sinai (Egypt), revised

Two pteropod and one alleged heteropod species preserved in a limestone slab from the Miocene of Wadi Gharandel, western Sinai, Egypt, are revised and shown to represent three pteropod species, viz. Limacina sp. [either L. inflata (d’Orbigny, 1836) or L. tertiaria (Tate, 1887)], Vaginella austriaca Kittl, 1886, and V. lapugyensis Kittl, 1886. The probable age of the so-called ‘Miocene Grits’ from which the slab was collected, as based on the pteropods, is Langhian to Early Serravallian (Middle Miocene).
