 Several sections of this species occur in the limestone. It is 

 easily recognized by its elongated contour and numerous chambers. 



T. sagittula has a wide range in time, being known as far back as 

 the Aptian. 



Pliocene : near Erment, right bank of Nile Valley. Frequent. 



Textularia agglutinans, d'Orbigny. (PI. II, Fig. G.) 

 Textularia agglutinans, d'Orb., 1839 : Foram. Cuba, p. 136, pi. i, 

 figs. 17, 18, 32-34. Brady, 1884 : Eep. Chall., voh ix, 

 p. 363, pi. xliii, figs. 1—3. 

 The specimen found in the limestone from Egypt is typical in 

 form, but rather small. In the fossil condition this species occurs 

 as far back as the Carboniferous Limestone formation. 



Pliocene : near Erment, right bank of Nile Valley. One specimen. 



Family GLOBIGERINID^. 



GLOBIGERINA, d'Orbigny [1826]. 



Globigerina conglobata, Brady. 



Globigerina conglobata, Brady, 1879 : Quart. Journ. Micr. Sci., 



vol. xix, N.S., p. 72 ; idem, 1884, Eep. Chall., vol. ix, 



p. 603, pi. Ixxx, figs. 1-5 ; pi. Ixxxii, fig. 5. 



The examples of the above species found in the Operculina- 



limestone are fairly typical, but are somewhat rounder in outline 



than recent specimens. G. conglobata appears to make its first 



appeai'ance in beds of Miocene age. 



Pliocene : near Erment, right bank of Nile Valley. Frequent.

GYPSINA, Carter [1877]. 



Gypsina vesigularis? (Parker & Jones).

 Gypsina vesicularis (Parker & Jones), Carter, 1877 : Ann. Mag. 



Nat. Hist., ser. iv, vol. xx, p. 173. 

 There is a fragment of a Gypsina occurring in one of our slides, 

 which seems to come nearest to the structure seen in G. vesicularis ; 

 on the other band, there is just the possibility that it is an irregular
