IN THE ESNA-IDFU REGION, NILE VALLEY, EGYPT 57 



3. G. pseudotriloba White is probably Globigerina linaperta Finlay. 



4. Apparently he had included under G. subcretacea Lomnicki several Hedbergella, 



Globigerinelloid.es, Rugoglobigerina, Globigerina and Globorotalia species, thus 

 extending its range from the Maestrichtian to the Lower Eocene. His 

 figured specimen is probably a species of Hedbergella or Globigerinelloides, 

 but the lack of a side view and the brief description make an accurate 

 determination impossible. 



5. G. membranacea (Ehrenberg) probably belongs to Globorotalia emilei sp. nov. 



while G. simulatilis (Schwager) should be assigned to Globorotalia rex Martin, 

 and G. velascoensis (Cushman) to G. velascoensis velascoensis (Cushman). 



Said & Kenawy (1956) recorded the following planktonic Foraminifera from the 

 Maestrichtian-Lower Eocene succession of the Giddi and the Nekhl sections, north- 

 ern Sinai, Egypt : Globotruncana aegyptiaca Nakkady, G. caliciformis Vogler, G. 

 conica White, G. esnehensis Nakkady, G. gansseri Bolli, G. lapparenti lapparenti 

 Brotzen, G. lapparenti tricarinata (Quereau), G. mayaroensis Bolli, G. intermedia 

 Bolli, G. stuarti de Lapparent; Rugoglobigerina " cretacea Cushman " of Bermudez 

 1952, R. esnehensis (Nakkady) ; Globigerina bulloides d'Orbigny, G. linaperta Finlay, 

 G. pseudotriloba White, G. subcretacea Lomnicki ; Globorotalia membranacea (Ehren- 

 berg) , Truncorotalia colligera (Schwager), T. crassata aequa (Cushman & Renz), 

 T. esnaensis (Le Roy), T. simulatilis (Schwager), T. spinulosa (Cushman), T. velasco- 

 ensis (Cushman), and T. wilcoxensis (Cushman & Ponton). 



Examination of their figures and very brief descriptions showed that : 



1. G. aegyptiaca Nakkady is an entirely single-keeled form which should be 



assigned to Globotruncana stuarti parva Gaudolfi. 



2. G. caliciformis (de Lapparent) (not Vogler), G. intermedia Bolli, G. stuarti (de 



Lapparent) and G. esnehensis Nakkady are all the same species and should be 

 assigned to Globotruncana esnehensis Nakkady & Osman. 



3. G. gansseri Bolli, G. lapparenti tricarinata (Quereau), R. esnehensis (Nakkady), 



G. cretacea Lomnicki, G. membranacea (Ehrenberg), T. esnaensis (Le Roy) 

 and T. spinulosa (Cushman) are doubtful forms. 



4. G. lapparenti lapparenti Brotzen probably belongs to Abathomphalus mayar- 



oensis (Bolli) as does G. mayaroensis Bolli. 



5. Rugoglobigerina " cretacea Cushman " of Bermudez, is possibly Globorotalia 



quadrata (White). 



6. Globigerina bulloides d'Orbigny is possibly Globorotalia pseudobulloides (Plum- 



mer), and both their G. linaperta Finlay, and G. pseudotriloba White probab- 

 ly belong to G. triloculinoides Plummer. 



7. T. colligera (Schwager) probably belongs to Globorotalia angulata abundo- 



camerata Bolli. Schwager's form was recorded from younger strata, and 

 the holotype of this species needs to be redrawn and redescribed as mentioned 

 above. 



8. T. crassata aequa (Cushman & Renz) and T. wilcoxensis (Cushman & Ponton) 



probably belong to Globorotalia aragonensis Nuttall.
