IN THE ESNA-IDFU REGION, NILE VALLEY, EGYPT 259 



APPENDIX 



While this work was in press, Said & Sabry published their work on " Planktonic 

 Foraminifera from the type locality of the Esna Shale in Egypt " (Micropaleontology, 

 10 : 375-395, pis. 1-3), and the following comments are made on the results of their 

 study : 



A. Concerning their biostratigraphical zonation. 



(1). Owing to their limited study, Said & Sabry have ignored the varied plank- 

 tonic foraminiferal fauna of the Maestrichtian and in addition to the fact that 

 practically all their Globotruncana species are wrongly identified they have 

 overlooked the following forms which characterize the Maestrichtian part of the 

 succession : 



Globotruncana adamsi sp. nov. G. leupoldi Bolli 



G. arabica sp. nov. G. lugeoni Tilev 



G. bahijae sp. nov. G. mariai Gandolfi 



G. conica White G. maviei Banner & Blow 



G. contusa contusa (Cushman) G. ovientalis sp. nov. 



G. contusa patelliformis Gandolfi G. rosetta pettersi Gandolfi 



G. contusa scutilla Gandolfi G. shavawnaensis sp. nov. 



G. contusa witwickae subsp. nov. G. stuarti parva Gandolfi 



G. cf. convexa Sandidge G. stuarti stuartiformis Dalbiez 



G. esnehensis Nakkady & Osman G. stuarti subspinosa Pessagno 



G. fareedi sp. nov. G. subcircumnodifer Gandolfi. 



G. fovnicata ackermanni Gandolfi G. tricarinata colombiana Gandolfi 



G. fornicata cesarensis Gandolfi G. tricarinata tricarinata (Quereau) 



G . fornicata fornicata Plummer G. ventricosa White 



G. fornicata globulocamerata subsp. nov. G. youssefi sp. nov. 



G. fornicata manaurensis Gandolfi Rugoglobigerina glaessneri Gandolfi 



G . fundiconulosa Subbotina R. loetterli (Nauss) 



G. gagnebini Tilev R. macrocephala Bronnimann 



G. cf. gagnebini Tilev R. pennyi Bronnimann 



G. gansseri dicarinata Pessagno R. rotundata Bronnimann 



G. gansseri gandolfii subsp. nov. A. mayaroensis (Bolli) 



G. gansseri gansseri Bolli 



G. gansseri subgansseri Gandolfi Trinitella scotti Bronnimann 



G. havanensis Voorwijk Abathomphalus intermedia (Bolli) 



(2). In their treatment of the Paleocene-Lower Eocene succession they have 

 almost literally followed Bolli's (19576) zonation, but their failure to recognize both 

 Globorotalia trinidadensis Bolli and G. compressa (Plummer) which flood the basal 

 part of the Paleocene has led them to discuss " a Globigerina daubjergensis-Globoro- 

 talia pseudobulloides zone ". Globorotalia pseudobulloides , however, ranges through- 

 out the Paleocene and cannot, therefore, be used for its subdivision. Their figured 

 Globigerina daubjergensis Bronnimann (pi. 3, figs. 8a-c) does not belong to this 

 species. 



Their references (p. 384, pi. 1, figs. i6a-c and p. 388, no figs.) to a Lower Landen- 

 ian Globorotalia pseudobulloides (Plummer) and a Danian Globigerina pseudobulloides 

 Plummer is rather confusing as both include Plummer's holotype (1926 : 133, pi. 

 8, figs, ga-c) in the relevant synonymies.
