From the Birket-el (^iirun s(*ries of tlie Zeuoloilon Valley, to tlie south-west of the lake, a 
cou.'ideralihi numher of laroe rostral teeth were collected by Mr. F)oa(lnell, and are in the Geological 
Museum, Cairo. These [u’ohahly belong to Stromer’s species Prist is ititjetis {tom. cit. p. 47 j. 
Cienns PROPRISTIS, Dames, 
[Sitzungsh. k. preuss. Akad. M iss. Berlin, math.-phys. Cl. 1883, p. 130.] 
In this genus the alveoli of the rostral teeth are not ossified, and their position is 
only marked by shallow indentations in the rostral margin.

Genus EOPRISTIS, Stromer. 
[Beitr. I’al. u. Geol. Oesterreich-Uugarus u. d. Orieuts, vol. w iii. ( 1!)05) p. 52 (as a 
suhgenus of /*rislis).] 
This form seems to be as distinct from I*risfis as is J'ropi istis, :tnd on tlud ticconut 
it is here regaidcd as of generic rank. In this genus there is no trace of tilvetdi for 
tlie teeth on the sides of the rostrum.
