Report on Foraminifera. By F. W. Millett. 
The Biloculine form has been found only at Stations 14 and 22. 
The other forms occur at most of the Stations, the Quinqueloculine 
being the most numerous of the three. 
4 Challenger ’ Stations are Prince Edward’s Island, Kerguelen 
Islands, and Bass Straits. Amongst other localities Dr. Egger records 
it from two 4 Gazelle ’ Stations off the coast of Australia. 
Miliolina circularis var. sublineata Brady, plate XI. fig. 4. 
Miliolina circularis var. sublineata Brady, 1884, Chall. Kept., 
p. 169, pi. iv. fig. 7. M. circularis var. sublineata Egger, 1893, 
Abhandl. k. bayer. Akad. Wiss., Cl. II. vol. xviii. Abth. ii. p. 237, 
pi. ii. figs. 78, 79. 
This rare variety differs from the 4 Challenger’ and 4 Gazelle 5 forms 
in having a cribrate aperture. The shell is thin and subtranslucent, as 
in the 4 Challenger ’ specimens. In size it considerably exceeds the 
specimens of M. circularis with which it is associated in the Malay 
Archipelago. 
It is rather plentiful at several stations in both areas. 
Brady gives but one locality, 44 off the Admiralty Islands on the 
north coast of New Guinea ” ; and the sole 4 Gazelle ’ station is off the 
coast of Mauritius. 
Miliolina valvularis Keuss sp., plate XI. figs. 5-7. 
Triloculina valvularis Reuss, 1851, Zeitschr. Deutsch. Geol. 
Gesell., vol. iii. p. 85, pi. vii. fig. 56. ? Miliolina valvularis (Reuss) 
Brady, Chall. Rept., p. 161, pi. iv. figs. 4, 5. Miliolina valvularis 
(Brady) Goes, 1894, Kongl. Svenska Yet.- Akad. Handl., vol. xxv. 
p. 115, pi. xxii. fig. 871. 
Whilst the aperture of this species, in general form, is similar to 
that of M. circularis, it differs in being provided with a tooth or 
valve which varies in size and form from a mere tubercule on the 
penultimate chamber to a large valve covering the whole of the aper- 
ture with the exception of a narrow semicircular slit at the margin. 
Speaking of M. valvularis , Brady says,* 44 The species is one of the 
few that may rank with Miliolina trigonula and Miliolina tricari- 
nata as a true Triloculina ” ; but in the Malay Archipelago it occurs 
also in the Biloculine and Quinqueloculine forms, and the figures by 
Goes above referred to represent it as having but two chambers visible 
externally ; however, these have not the symmetry characteristic of 
Biloculina, and the arrangement of the earlier chambers is Triloculine 
or Quadriloculine. 
The Quinqueloculina dilatata d’Orb., from the Gulf of Marseilles, 
figured by Schlumberger,t resembles the wild growing forms of 
M. valvularis. Biloculine forms similar to this species, if not identical,
