Recent Foraminifera off the East Coast of Australia. 357 



Truncatulina haidingerii (d'Orbigny). 



Botalina haidingerii d'Orbigny, 1846, For. Fobs. Vienne, p. 154, pi. viii, 



figs. 7-9. 

 Truncatulina haidijigerii Brady, 1884, Chall. Eept., p. 663, pi. xcv, fig. 7. 



Similar to the " Challenger " tests in every respect. 



Truncatulina reticulata (Czjzek). 



Botalina reticulata Czjzek, 1848, Haidinger's Naturw. Abhandl., vol. ii^ 



p. 145, pi. xiii, figs. 7-9. 

 Truncatulina reticulata Brady, 1884, Chall. Eept., 669, pi. xcvi, figa. 5-8. 



The examples are well developed. 



Truncatulina pygmcea Hantken. 



Truncatulina pygnma Hantken, 1875, Mittheil. Jahrb. d. k. ung. geol. 



Anstalt, vol. iv, p. 78, pi. x, fig. 8. 

 T. pygmcea Brady, 1884, Chall. Kept., p. 666, pi. xcv, figs. 9, 10. 



This is one of the best represented forms of the Truncatulina 

 in the gathering. The convexity of the superior surface varies. 

 The lobulation of the periphery and the slight roughness of both 

 the surfaces are distinctive. 



Truncatulina culter (Parker and Jones). 



Planorbulina culter Parker and Jones, 1865, Phil. Trans., vol. civ, p. 421, 



pi. xix, fig. 1. 

 Truncatulina culter Brady, 1884, Chall. Kept., p. 668, pi. xcvi, fig. 3. 



This, again, is one of the well-represented forms. Most of the 

 tests show "a certain amount of colouring of a light brown shade. 

 In one case the keel is well developed. 



Truncatulina tenera Brady. 

 Truncatulina tenera Brady, 1884, Chall. Rept., p. 665, pi. xcv, fig. 11. 



Brady mentions the difficulty of distinguishing between T. 

 tenera and Puhinulina umhonata Eeuss. I have placed the 

 specimens under the above heading on account of the pronounced 

 lobulation of the test, which, in the " Challenger " illustrations of 

 the two forms, is much more marked in T. tenera Brady than in 

 P. umhonata Eeuss. 



Truncatulina tenuimargo Brady. (PI. VI, figs. 20, 21.) 



Truncatulina tenuimargo Brady, 1884, Chall. Rept., p. 662, pi. xciii, figs. 2,5, 

 T. tenuimargo Egger, 1893, Abhandl. k. bayer. Acad. Wiss., cl. ii, vol. 



xviii, p. 399, pi. xvi, figs. 7-9. 

 T. tenuimargo Heron-Allen and Earland, 1908, etc., Rec. and Foss. Foram. 



Selsey Bill, Sussex, Journ. Roy. Micr. Soc, 1909, p. 680, pi. xx, fig. 2. 



A most interesting set. 



The small form (fig. 3 in the Chall. Eept.) is present ; but
