In a collection of Cretaceous fossils from Sinai obtained by Mr. T. Barron, F.G.S., which has been entrusted to me for determination by the Geological Survey of Egypt, I found several specimens of Linthia oblonga, a form of Echinoid which appears to have escaped the attention of modern writers on the palæontology of the Sinai Peninsula. In tracing the history of this species it is ascertained that d'Orbigny first figured and described it under the genus periaster during the year 1856 in the Pal. Française Terr. Crétacés Échinodermes, pl. 900, pp. 275, 276, where it is referred to as having been collected by M. Lefébvre at Mount Garèbe, near Suez, from rocks regarded as of Turonian age, in association with Radiolites.
