Pulvinulina hauerii (d'Orbigny), 



Botalina hauerii d'Orbigny, 1846, For. Foss. Vien., p. 151, pi. vii, figs. 22-24. 

 Pulvinulina hauerii Brady, 1884, Chall. Kept., p. 690, pi. cvi, figs. 6, 7. 



Except that the tests are not quite so stout, the examples agree 

 with the " Challenger " fig. 7. 



Botalia Lamarck. 



Botalia orbicularis (d'Orbigny). 



Gyroidina orbicularis d'Orbigny, 1826, Ann. Sci. Nat., vol. vii, p. 278, No. 1, 



Modele No. 13. 

 Botalia orbicularis Brady, 1884, Chall. Eept., p. 706, pi. cvii, fig. 5 ; 



pi. cxv, fig. 6. 



Good examples of this neat form occur. 



Most of the specimens are of a clear light brown tint, deepen- 

 ing at the centre of the superior face. 



The tests are highly polished, and some of them are almost 

 flat on the upper surface. 



Botalia soldanii (?) d'Orbigny. (PI. VI, figs. 27-29.) 



Botalia {Gyroidiiia) soldanii d'Orbigny, 1826, Ann. Sci. Nat., vol. vii, p. 278, 

 No. 5, Modele No. 36. 



Test polished ; superior surface, if anything, rather more convex 

 than the inferior; umbilicus flush, not excavated; periphery rounded; 

 aperture a curved slit on the inferior face of the last segment, close 

 to the line of union of the previous convolution. 



The specimens may be a pauperate form of B. soldanii, but 

 this is open to question, and therefore I have put a query. The 

 chief interest regarding this form is the presence of a " balloon " 

 chamber on three out of the eight examples found, and a fourth 

 (figs. 28, 29) shows traces either of its having had a " balloon " 

 chamber, or of one having been commenced. The orifice and a 

 considerable area of the test are enclosed by this extra chamber.

8-10. 



Both the forms figured in the " Challenger " Kept, are present. 

 The larger one, with the fewer and more inflated chambers, is 

 frequent ; the other very rare.
