and small), N. Ramondi, N. cnrvispira, and N. intermedia ; whilst 

 from "the lowest rock seen just beyond Pharaoh's Fall " he records 

 remains of Nummulites Ramondi and Opercidina canalifera (?). 



Foraminifera have been recorded from Sinai also by Ehrenberg.^ 

 These were principally obtained from washings of the rocks, and 

 •consequently are exceptionally minute forms. 



Other occurrences of foraminifera from the adjacent country, 

 chiefly Palestine, are noted by Fraas," who described a form under 

 the name of Nummulites cretacea from the Hippurite Limestone 

 near Jerusalem, and which from the figure given is certainly not 

 a nummulite, but beai's some resemblance to a turgid Orbitoides, and 

 is most probably of Tertiary age.^ The same author mentions two 

 other species, Nummulites variolaria and N. Arabiensis. 



Lartet has figured and noted three species of Nummulites from 

 Wadi Gharandel,* namely, N. LijeUi, N. Guettardi, and N. Lucasana. 



Lastly, a series of specimens collected by the Palestine Exploring 

 Expedition in 1865 from Gerizhem have been identified by Professor 

 T. Kupert Jones,^ who enumerates ten species, and some of these are 

 comparable with our Sinaitic specimens. 



The specimens dealt with in this paper were collected by 

 Mr. Barron, of the Egyptian Geological Survey, between January 

 and June, 1899. 



The following is an epitomized account of the rock-specimens, 

 with their contents : — 



TSo. 4,111, 11. — " Foraminiferal limestone; top of Jebel Abyad, 

 south of Wadi Gharandel, Sinai." Mokattam Series (Middle Eocene). 



A dense cream-coloured limestone, largely composed of Nummulites 

 subdiscorbina and N. curvispira, associated with a fair number of 

 N. Gizehensis, var. Paclioi. The nummulites in these rock- specimens 

 lie massed together, forming a kind of bank, which is in turn covered 

 with fine detiital mud containing smaller foraminifera, such as 

 Bolivina, Globigerina, Discorbina, and Rotalia. One of the nummu- 

 lites in this rock has been partially transformed into beekite. 



The genera and species found in these rock-specimens are : — 

 Bolivina punctata ?, d'Orbigny ; Globigerina bulloides, d'Orb. ; G. con- 

 globata, Brady; G. cretacea"^, d'Orb.; Discorbina rugosa (d'Orb.); 

 D. globidaris (d'Orb.) ; Rotalia calcariformis (Schwager) ; Nummulites 

 subdiscorbina, De la Harpe ; JV^. curvispira, Meneghini ; N. Gizehensis, 

 Ehr., var. Fachoi, De la Harpe; Orbitoides dispansa (Sow.); 0. 

 epliippium (Schlotheim) ; and 0. papyracea (Boubee).

6 Mr. Barron writes (March, 1900) with regard to this deposit: "It has the 

 characters of a beach deposit iu that it is gritty and contains well-marked con- 

 glomerate beds. There is no doubt, however, that it is part of the Eocene series."
