A new species; apparently this is the form quoted by Blanckenhorn and Mayer-Eymar as _T. angulata_. According to Cossmann, however, _T. pharaonica_ differs from _T. angulata_ in several particulars, especially in being more thickset.] [Footnote 56: Blanckenhorn, thinking that the bed capping the island of Geziret el Qorn is identical with that forming the plain around and to the north of Dimê, has, in a section recently published (_Neues zur Geol. u. Palænt. Ægyptens, IV. Das Pliocän_, etc., Zeitschr. d. Deutsch. geol. Gesellsch., Jahrg. 1901, Taf. XIV, fig. 2), inserted a number of faults letting the beds down continually to the south. The beds however are not identical, and no faults occur.] [Footnote 57: This block was far too large to transport by camel, but it may be feasible to effect its removal to Cairo by cart when opportunity offers.] [Footnote 58: SCHWEINFURTH, op. cit. p. 139.] [Footnote 59: A ruin discovered by Schweinfurth in 1886 and hence often spoken of as “Schweinfurth’s Temple.” Nothing certain is known as to its age or former use, but we may infer from its situation just beyond the limits of the high-level lacustrine clays, that it was built and inhabited only while Lake Mœris stood at its highest level.] [Footnote 60: See OPPENHEIM, op. cit. p. 105.]
