Miliolina Boueana d’Orbigny sp. 
Quinqueloculina Boueana d’Orbigny, 1846, Foram. Foss. Vienne, 
p. 293, pi. xix. figs. 7-9. M. Boueana (d’Orb.) Goes, 1894, K. 
Svenska Vet.-Akad. Handl., vol. xxv. p. 114, pi. xxi. fig. 865. 
This form is not well represented, and the specimens might almost 
with as much reason have been included in the Miliolina oblonga 
group. 
It occurs at a few Stations in both Areas.

Bull. Soc. Geol. France, ser. 3, vol. x. p. 425, figure. M. alveolini- 
formis (Brady) Brady, 1884, Chalk Rept., p. 181, pi. viii. figs. 15-20. 
M. alveoliniformis (Brady) Egger, 1893, Abhandl. k. bayer. Akad. 
Wiss., Cl. II., vol. xviii. p. 232, pi. ii. figs. 17-19. 
This abnormal form of Miliolina is tolerably common and well 
developed at Station 22 in Area 2. All the specimens have the 
porous aperture as represented by Brady and Munier-Chalmas, thus 
differing from the example figured by Egger. In my cabinet are 
specimens from ‘ Challenger’ Station 172, Nukualofa, Tongatabu, which 
are more regular in form, are entirely porcellanous, and the aperture 
resembles that of M. circularis. 
Brady speaks of it as being essentially a coral reef species, and as 
having a wide range. The localities given by Munier-Chalmas for 
Schlumbergerina arenipliora are the coast of Madagascar and the 
Gaboon and Torres Strait. The ‘ Gazelle ’ Stations are, off the Cape of 
Good Hope and Mauritius.

Articulina sulcata Reuss, 1850, Denkschr. k. Akad. Wiss., vol. i. 
p. 383, pi. xlix. figs. 13-17. A. sulcata (Reuss) Brady, Parker, and 
Jones, 1888, Trans. Zool. Soc., vol. xii. pt. vii. p. 215, pk xl. fig. 11. 
A. sulcata (Reuss) Egger, 1893, Abhandl. k. bayer. Akad. Wiss., 
Cl. II., vol. xviii. p. 243, pk ii. fig. 5. 
The specimens of this species are neither numerous nor widely 
distributed. They are of the form figured by Brady and by Egger, 
which differs slightly from those figured by other authors. 
Brady records four < Challenger ’ Stations, one of which is Raine 
Island, Torres Strait. The * Gazelle ’ Stations are West Africa and 
Mauritius.
