Spiroloculina impressa Terquem. 



Spiroloculina impressa Terquem, 1878, Mem. Soc. Q6ol. Fr., ser. 3, vol. i, 



p. 53, pi. X, fig. 8. 

 S. impressa Brady, 1884, Chall. Eept., p. 151, pi. x, figs. 3, 4. 

 S. impressa Sidebottom, 1904, Eec. Foram. Isl. Delos, Mem. Manchester 



Lit. Phil. Soc, vol. xlviii. p. 15, pi. ii, figs. 9-11. 



The specimens are small, but agree well with the " Challenger " 

 and " Delos " tests. 



Spiroloculina nitida d'Orbigny. (PI. I, fig. 4.) 



Spiroloculina nitida d'Orbigny, 1826, Ann. Sci. Nat., vol. vii, p. 298, No. 4. 

 S. nitida, Millett, 1898, etc.. For. Malay Archipelago, Journ. Roy. Micr. 

 Soc, p. 265, pi. v, figs. 9-13. 



The specimens are in a curious condition, looking as if they had 

 been plastered over with debris, and it is difficult to make out the 

 earlier chambers. The surface is dull. The final chamber is 

 produced, and swollen near the orifice. Three found. 



Spiroloculina tenuis Czjzek. 



Quinqueloculina tennis Czjzek, 1848, Haidinger's Naturw. Abhandl., vol. ii, 



p. 149, pi. xiii, figs. 31-34. 

 Spiroloculina tennis Brady, 1884, Chall. Eept., p. 152, pi. x, figs. 7-11. 



Two varieties. One typical, and the other similar to the 

 " Challenger " illustration, pL x, fig, 9. 



Spiroloculina acutimargo Brady. 

 Spiroloculina acutimargo Brady, 1884, Chall Eept., p. 154, pi. x, figs. 12-15. 



Both forms as represented by the " Challenger" figures, 12, 13, 

 are present. 



Spiroloctilina tenuiseptata Brady. (PI. I, figs. 5-7.) 

 Spiroloculina tenuiseptata Brady, 1884, Chall. Eept., p. 153, pi. x, figs. 5, 6. 



Figs. 5, 6. — This is an interesting, almost circular form. The 

 " shelly septum " is concealed by granular substance in most cases, 

 but a specimen mounted in Canada balsam reveals it clearly, as 

 shown in fig. 6. The peripheral edge is channelled. The orifice is 

 situated at the end of a produced neck. In fig. 6 the neck is 

 broken off. Under the name Spiroloculina dorsata Eeuss, var. 

 ctrculaiis, Chapman (1915, Zool. Ees. "Endeavour," Nat. Mus. 

 Melbourne, vol. iii., pt. 1, p. 7, pi. i, fig. 1) figures a form which 

 appears to be like that illustrated and described above, but he 

 gives few particulars, and without seeing his specimens it is 

 impossible to say whether our specimens are identical or not. The 

 arrangement of the early chambers as viewed in balsam strongly
