Bolivina hantkeniana Brady. 



Bolivina hantJceniana Brady, 1881, Quart. Journ. Micr. Sci., vol. xxi, 



N.S.,p. 58. 

 B. hanfkcniana Brady, 1884, Chall. Eept., p. 424, pi. liii, figs. 16-18. 



Three rather small tests and a large one were found. 



They are of the elongate type. In the case of the large speci- 

 men the chambers on one side of the alternating series are much 

 more inflated than on the other. 



Bolivina plicata d'Orbigny. 



Bolivina plicata, 1839, Foram. Amer. Merid., p. 62, pi. viii, figs. 4-7. 

 B. plicata Halkyard, 1889, Trans, and Ann. Eept. Manchester Micr. Soc, 

 p. 65, pi. i, fig. 13. 



Four occur, but they are not quite characteristic. Perhaps the 

 usual markings are concealed through age. 



Bolivina tortuosa Brady. 



Bolivina ^oriwosa Brady, 1879, etc., Quart. Journ. Micr. Sci., 1881, N.S., p. 57. 

 B. tortuosa Brady, 1884, Chall. Eept., p. 420, pi. lii, figs. 31-34. 

 B. tortuosa Heron-Allen and Earland, 1915, Foram. Kerimba Archipelago, 

 pt. ii. Trans. Zool. Soc, London, vol. xx, pt. xvii, p. 645. 



One typical specimen, and one which is probably identical with 

 the variation mentioned by Heron- Allen and Earland in the above 

 reference. As they remark, " the test is covered with raised and 

 contorted lines of shell-substance." I have also four examples of 

 this variation from South Australia, so that it appears to be a 

 definite form. 



Bolivina Tcarreriana Brady. 



Bolivina Tcarreriana Brady, 1881, Quart. Journ. Micr. Sci., vol. xxi, 



N.S., p. 58. 

 B. karrcriana Brady, Chall. Eept., p. 424, pi. liii, figs. 19-21. 



Three typical specimens. 



Bolivina lobata Brady. (PI. Ill, figs. 20, 21.) 



Bolivina lohata Brady, 1881, Quart. Journ. Micr. Sci., vol. xxi, N.S., p. 58. 

 B. lohata Brady, 1884, Chall. Eept., p. 425, pi. liii, figs. 22, 23. 

 B. lobata Herou-AUen and Earland, 1915, Foram. Kerimba Archipelago, 

 pt. ii. Trans. Zool. Soc, vol. xx, pt. xvii, p. 647. 



The examples are not so fully developed as the " Challenger " 

 specimens, being shorter. The aperture is situated in a depression 

 and is not " a long oval slit contracted at the middle " as stated by 

 Brady in his description of the species. 



Millett, in his Malay Eept., 1898, etc., Journ. Eoy. Micr. Soc, 

 1900, p. 6, pi. i., fig. 2, figures an example showing a further de- 

 velopment, under the name Bigenerina fiinbriata. Eight occur.
