222 Dr. R. L. Sherlock — Foraoninifera of Speeton Clay. 



Family TEXTULARIID^. 



Sub-family TEXTULAEIINJE. 



Textulakia, Def ranee. 



Texhdaria agglutinans, d'Orb. 



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

 figs. 17, 18, 32-4. 



Remarks. — The species is recorded from the Folkestone Gault 

 (Chapman), the Red Chalk of Speeton (Burrows, Sherborn, & Bailey), 

 and is still living at widely different depths (Brady). 



Horizon. — A simple specimen was found in B base c and lost. 



BiGENEEiNA, d'Orbigny. 

 Bigenerina nodosaria, ? d'Orb. (PL XVIII, Fig. 2.) 



Bigenerina nodosaria, d'Orbigny, 1827 : Ann. Sci. Nat., vol. vii, p. 261, No. 1, 



pi. xi, figs. 9-12 ; Modele No. 57. 

 B. nodosaria, Terrigi, 1880: Atti dell'Accad. Pontif., ann. xxxiii, p. 192, 



pi. li, fig. 28. 

 B. nodosaria, Brady, 1884 : Chall. Eep., vol. ix, p. 369, pi. xliv, figs. 14-18. 



Remarks. — The single specimen found has only two cells in the 

 uniserial portion of the shell, and the arrangement of the initial cells 

 is not clear, so that there is some doubt as to the determination. 

 The species has been recorded in the Miocene of the Viennese Basin 

 and of Malta (d'Orbigny, Parker & Jones), and in the later Tertiaries 

 of IN'orth Germany (E-oemer), Italy (Costa, Terrigi), and Spain 

 (Parker & Jones). Brady states that it is common in the North 

 Atlantic and is also found in the North Pacific at depths varying from 

 7 to 1,630 fathoms. 



Horizon. — Found in B base c. One specimen. 



Gaudetina d'Orbigny. 

 Gaudryina Jiliformis, Berthelin. (PI. XVIII, Fig. 4.) 



Gaudryina filiformis, Berthelin, 1880 : Mem. Soc. geol. France, ser. iii, vol. i, 



No. 5, p. 25, pi. i, fig. 8. 

 G. filiformis, Wright, 1882: Proc. Belfast Nat. Field Club, 1880-1, App.,

 G. filiformis, Chapman, 1892 : Journ, Eoy. Micr. Soc, p. 752, pi. xi, fig. 7. 



Remarks. — The triserial commencement of this form is very small 

 and difficult to make out. The species is known from the Gault of 

 France (Berthelin) and of Folkestone (Chapman). It is still living, 

 and has been recorded from shallow water by Wright, Balkwill, and 

 Robertson, and by the Cliallenger Expedition from four stations at 

 depths varying from 390 to 620 fathoms. 



Horizon. — Found in B base c. Two specimens. 



Sub-family BULIMIN^. 

 BxjLiMiNA, d'Orbigny. 

 Bulimina sp. 

 A broken and coarsely arenaceous specimen of this genus was found 

 in Dj (base).
