Report on Foraminifera. By F. W. Millett, 543 



The examples are few and small, but are distribute! over both 

 Areas. 



According to Brady it is a North Atlantic species, but there are 

 ' Gazelle ' Stations in the Indian Ocean and in the South Pacific. 



Bolivina tortuosa Brady. 



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

 n.s. p. 57. B. tortuosa Brady, 1884, Chall. Bept., p. 420, pi. lii. 

 tigs. 31-34. B. tortuosa (Brady) Egger, 1893, Abhandl. k. bayer. 

 Akad. Wiss., CI. II. vol. xviii. p. 298, pi. viii. figs. 43, 44. 



This form, which appears to be nothing more than a twisted 

 variety of B. dilatata, is rare in the Malay Archipelago, although the 

 specimens are characteristic and fine. It is most numerous in Area 1. 



It is abundant at ' Challenger' Station No. 120, off Pernambuco, 

 675 fathoms. This locality is not mentioned by Brady in his Beport, 

 and the depth of water is greater than at any of the Stations recorded 

 by him. 



Bolivina robusta Brady. 



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

 n.s. p. 57. B. robusta Brady, 1884, Chall. Kept., p. 421, pi. liii. figs. 

 7-9. B. robusta (Brady) Egger, 1893, Abhandl. k. bayer. Ak. Wiss., 

 01. II. vol. xviii. p. 294, pi. viii. figs. 31, 32. 



This species, so widely distributed over the globe, yet so rarely 

 •ecorded, occurs sparingly in the Malay Archipelago, at Stations 

 in both Areas. The examples are rather feeble, and approach B. 

 dilatata. 



It is very abundant in the Tertiary clay of St. Erth. 



Bolivina limbata Brady. 



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

 n.s. p. 57. B. limbata Brady, 1884, Chall. Rept., p. 419, pi. lii. figs. 

 26-28. B. limbata (Brady) Egger, 1893, Abhandl. k. bayer. Akad. 

 Wiss., CI. II. vol. xviii. p. 300, pi. viii. figs. 10-12. 



A few specimens occur in both Areas, but they are not quite 

 typical, the margin being more rounded than usual. 



The ' Gazelle ' Stations are West Africa and Mauritius. 



Bolivina lobata Brady, plate I. fig. 4. 



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

 n.s. p. 58. B. lobata Brady, 1884, Chall. Kept., p. 425, pi. liii. figs. 

 22, 23. B. lobata (Brady) Egger, 1893, Abhandl. k. bayer. Akad. 

 Wiss., CI. II. vol. xviii. p. 300, pi. viii. figs. 55, 56. 



In Part VII. of this Beport, this species has already been figured 

 and alluded to in relation to Bigenerina jimbriata* It well illus- 



_ * Possibly this form might as conveniently have been assigned to the genus 

 Bifarina. See this Journal, ante, p. 6.
