neighbours, as shown in figs. 10, 11 ; at other times they combine to 
form a symmetrical inflation of the test, as in fig. 12. In the Malay 
specimens these variations are very numerous, and aflord materials for 
bringing together figures by various authors, the affinities of which 
have hitherto been very doubtful. 
Of the figures in which the inflation of individual chambers 
occurs, the following may be mentioned : — T. globigera Schwager, 
1866, Novara-Exped., Geol. Theil, vol. ii. pi. vii. fig. 100 ; T. sagit- 
tula var. Soldanii Fornasini, 1883, Boll. !Soc. Geol. I tab, vol. ii. 
pi. ii. fig. 2; T. Soldanii Fornasini, 1887, Boll. Soc. Geol. Ital., 
vol. vi. pi. ix. figs. 3, 4 ; T. conica Chapman, 1892, Journ. B. Micr. 
Soc., pi. vi. fig. 20; T. agglutinans forma jugosa Goes, 1891, K. 
Svenska Vet.-Akad. Hand!., vol. xxv. pi. vii. figs. 297-299 ; and 
T. luculenta Brady, 1884, Chall. Kept., p. 364. The inflation in 
the last-mentioned form is not represented in Brady’s figures, but 
I have specimens from ‘ Challenger ’ Station 24 (off Culebra Island ) 
in which it is well shown. This variety is represented by figs. 10, 11, 
plate VII. 
The figured specimens of the other form in which the later seg- 
ments combine to form a club-shaped test are : — T. Candtina d’Or- 
bigny, 1839, Foram. Cuba, pi. i. figs. 25-27 ; Plecanium acumina- 
tum Seguenza, R80, Atti K. Accad. Lincei, ser. 3, vol. vi. pi. x. fig. 5 ; 
T ’ fungiformis Fornasini. 1887, Boll. Soc. Geol. Ital., vol. vi. pi. x. 
fig. 1, and 1896, Mem. R. Accad. Sci. 1st. Bologna, ser. 5, vol. vi. 
pi., 1-5; and T. cordiformis Terquem, 1883, Cinq. Mem. Foram. 
Oolithique, pi. xlv. fig. 5. The Malay form of this variety is repre- 
sented by fig. 12, pi. VII. 
The most numerous and regular, and therefore probably the most 
typical, form of this variety of T. sagittula closely resembles T. aciculata 
d’Orbigny in the shape and arrangement of the chambers forming the 
later portion of the test, but the margins are obtuse instead of being 
acute as in that species. This particular form is found at a consider- 
able number of the Malay Stations ; the inflated varieties are more 
rare and more local.
