Note 39 — Chapter V

Letter from Prof. Zittel to Capt. Lyons, dated May 19th, 1894. It was afterwards suggested (Beadnell, op. cit. Int. Geol. Congress, p. 10) that these specimens were possibly not E. Overwegi at all, and Mr. Bullen Newton, of the British Museum, who has undertaken the determination of the Baharia collection, confirms this, stating that the so-called specimens of Exogyra Overwegi, referred to in Capt. Lyons’ paper, are in reality examples of E. mermeti.
