C. 10205. Itostral tooth, prohahly of tliis species. 
i*’rom tlie Birket-el- Qunin series of the Zeuglodon Valley, to the south-west of the lake, a 
<'onsi(leral)le nuniher of large rostral teeth were collected by Mr. Beadnell, and are in the Geological 
.Museuin, Cairo. These probably belong to Stromer’s species Pristis ingens (tom. cit. p. 47). 
Genus PROPRISTIS, Dames. 
[Sitzungsh. k. preuss. Akad. Wiss. Berlin, math.-j»hys. Cl. 1883, ]). 13().] 
Ill this genus the alveoli of the rostral teeth are not ossified, and their position is 
only marked by shallow indentations in the rostral margin.

Remains of this species are not uncommon in the same beds as those from which 
rostra of Pristis fajumensis are obtained. 
Form. & Loc. — Qasr-el-Sagha beds (Middle Pdocene) : north of Birket-el-(iurun.

Genus EOPRISTIS, Stromer. 
[Beitr. Pal. n. Geol. Oesterreich-Ungarns u. d. Orients, vol. xviii. (ll)()5j p. 52 (as a 
subgenus of Pristis).'\ 
This form seems to be as distinct from Pristis as is l^ropristis, and on that account 
it is here regarded as of generic rank. In tltis genus there is no trace of alveoli for 
the teeth on the sides of the rostrum.
