3. Biloculina elongata, d'Orbigny. (Plate XL. figs. 21, 22.) 

 Biloculina elongata, Chall. Report, p. 144, pi. 2. fig. 9. 



At 260 fathoms ; specimens small. 



4. Biloculina irregularis, d'Orbigny. (Plate XL. figs. 24, 26.) 

 Biloculina irregularis, Chall. Report, p. 140, pi. 1. figs. 17, 18. 



A variable form. The test is of rounded contour, stoutly built, and subject to a 

 certain amount of flattening in a direction at right angles to the usual plane of com- 

 pression. It was first figured by d'Orbigny in his memoir on South-American Forami- 

 nifera (pi. viii. figs. 22-24). Rare, at 260 fathoms. 



Spiroloculina, d'Orbigny. 



5. Spiroloculina planulata, Lamarck, sp. (Plate XL. figs. 14, 15.) 

 Spiroloculina planulata, Chall. Report, p. 148, pi. 9. fig. 11. 



Occurs in one sounding only, 40 fathoms. Some of the specimens (fig. 15) show a 

 tendency to the external thickening of the sutural lines characteristic of S. limbata. 



6. Spiroloculina asperula, Karrer. (Plate XL. figs. 28, 29.) 

 Spiroloculina asperula, Chall. Report, p. 152, pi. 8. figs. 13, 14. 



The figures here given of this species are somewhat defective ; they fail to render the 

 granular or arenaceous condition of the test, which is a marked feature of the specimens. 

 In the two deeper soundings ; somewhat rare. 



Miliolina, Williamson. 



7. Miliolina seminulum, Linne, sp. (Plate XL. figs. 23, 31.) 

 Miliolina seminulum, Chall. Report, p. 157, pi. 5. fig. 6. 



Small specimens of this common form occur at almost all the stations. 



8. Miliolina oblonga, Montagu, sp. (Plate XL. fig. 27.) 

 Miliolina oblonga, Chall. Report, p. 160, pi. 5. fig. 4. 



Small specimens, generally associated with the last-named species. 



9. Miliolina ptgm^ea, Eeuss, sp. (1). (Plate XL. fig. 30.) 

 Miliolina pygmcea, Chall. Report, p. 163, pi. 113. fig. 16. 



The figured specimen probably belongs to this species, but is not by any means a 

 well-marked example. At Station IV. ; 260 fathoms. 



10. Miliolina bicornis, Walker and Jacob, sp. (Plate XL. fig. 25 * 

 Miliolina bicornis, Chall. Report, p. 171, pi. 6. figs. 9, 11, 12. 



One or two poorly-shaped, feebly-corrugated specimens, well represented by the
