698 MR. E. CHAPMAN OK THE BARGATE BEDS OP SURREY. [Nov. 1 894, 



Family TEXTTJLAEIID^E. 



Subfamily Textulariina 



Textularia, Defrance. 



17. Textularia sagittula, Defrance. 



T. sagittula, Defrance, Diet. Sci. Nat. vol. xxxii. (1824) p. 177, 

 vol. liii. p. 344 ; Atlas Conch, pi. xiii. fig. 5 ; Brady, ' Challenger ' 

 Rep. vol. ix. (1884) p. 361, pi. xlii. figs. 17, 18. 



To this species must be assigned some Bargate specimens which 

 are compressed, cuneiform, or sagittate, and with more or less sharp 

 edges. These Neocomian specimens are, however, about one-third 

 the usual size, their average length being only y^ inch (0*25 mm.). 



T. sagittula has hitherto made its first appearance in Upper 

 Cretaceous beds (Gault and Chalk), and is fairly common in all 

 newer deposits up to the present time. 



Eight specimens from beds below Folkestone series in Horsham 

 Road-cutting, Dorking. 



18. Textularia gramen, d'Orbigny. 



T. gramen, d'Orbigny, ' Foram. Foss. Yienne,' 1846, p. 248, pi. xv. 

 figs. 4, 6 ; Brady, ' Challenger ' Rep. vol. ix. (1884) p. 365, pi. xliii. 

 figs. 9, 10. 



This species occurs in the Bargate series, but is smaller than 

 usual ; in some cases the specimens closely approach T. globulosa, 

 Ehrenberg, 1 in the inflation of tbe last two chambers. 



From Pebble-beds, Littleton (six specimens) ; in Bargate Beds, 

 Holloway Hill (two) ; and in beds below Folkestone series, Horsham 

 Road, Dorking (two). 



19. Textularia pr^longa, Reuss. 



T. prcelonga, Reuss, ' Verstein. bohm. Kreid.' pt. i. (1845) p. 39, 

 pi. xii. fig. 14. 



This species is represented from the Bargate series by one speci- 

 men from the Littleton Pebble-beds, and one from the beds below 

 the Folkestone series, Horsham Road, Dorking. 



20. Textularia mlntuta, Berthelin. 



T. minuta, Berthelin, Mem. Soc. geol. France, ser. 3, vol. i, 

 (1880) no. 5, p. 26 2 ; Chapman, Journ. Roy. Micr. Soc. 1892, 

 p. 327, pi. vi. fig. 15. 



The examples found are similar to those from the Folkestone 

 Gault both in size and form. 



Five specimens from Bargate Pebble-beds, Littleton. 



* Abhand. Ak. Wiss. Berlin (1838), 1839, p. 135 (no. 60), pi. iv. fig. (3. 



2 This species is the same as that figured by Reuss under the name of 

 T. pygmcea, Sitzungsb. Ak. Wiss. Wien, vol. xlvi. (1862) p. 80, pi. ix. fig 11 ;. 

 the specific term pygmcea having been previously used for another Textularian 

 type by A. d'Orbigny, it was afterwards renamed by Berthelin to avoid con- 

 fusion.
