One specimen. Previously recorded from four localities of the London 

 Clay, (See the former paper, p. 760, Trochammina.) 



Textulakia Defrance [1824]. 



Textularia agglufinans d'Orbigny, var., plate XI. fig. 10. 

 D'Orbigny, Foram. Cuba, 1839, p. 136, plate i. figs. 17, 18, 32-34. 

 — This variety of T. agglutinans, with its rounded chambers and 

 subcylindrical form, is comparable with Brady's var. porreda (Report, 

 ' Challenger,' 1884, p. 364, plate xliii. fig. 4). 



Clavulina d'Orbigny [1826J. 



Clavulina parisiensis, d'Orbigny, plate XI. fig. 11. D'Orbigny, 

 Ann. Sci. Nat., vii. (1826) p. 268, No. 3 ; Modele, No. 66.— The 

 specimen mentioned at p. 743 of our former paper is here figured, and 

 is the only example found which shows the characteiistic triangular 

 shape of the early chambers. Dr. Brady mentions its occurrence in 

 abundance in the London Clay near Clapham Common.* 



Chilostomella Keuss [1849]. 



Chilostomella ovoidea Eeuss, plate XI. fig. 12. Reuss, Denkschr. 

 k. Ak. Wiss. ^Yien. i. (1849) p. 380, plate xlviii. fig. 12 a-e.— One 

 specimen. New to the London Clay. 



Chilostomella oviformis Sherborn and Chapman, plate XI. fig. 13. 

 Lagena (Ohliquina) oviformis, Sherborn and Chapman, Journ. R. 

 Micros. Soc, ser. 2, vi. 1886, p. 745, plate xiv. figs. 19 a-d. — The 

 erroneous reference of this form to Lagena was principally due to the 

 fact that the interiors of the specimens described were occupied by sand. 

 We have now been so fortunate as to secure a few more specimens 

 which have the internal structure preserved, and we have no hesitation 

 in referring the form to Chilostomella. This is also the opinion of 

 Dr. Brady who has kindly examined our specimens. The interest of 

 this form of Chilostomella Hes in the fact that the successive external 

 chamber envelopes the whole of the previous structure, and thus 

 presents what appears to be a test of a single chamber. We give a 

 dotted outline of the internal structure restored from several partially 

 perfect individuals, and have nothing to add to the original description 

 of the exterior.
