the species to Tnloculina in the text of the “Cuba” monograph, to Quinqueloculina on 
the plate, a sufficient evidence of its variability. Under the name Quinqueloculina 
angustissima (Denkschr. d. k. Akad. AViss., vol. i. p. 384, pi. xlix. fig. 18), Prof. Reuss 
describes a Miocene variety of similar feeble habit, which except in being somewhat 
thinner, differs but little in contour from the recent form. 
The Challenger specimens of Miliolina gracilis are from Humboldt Bay, Papua, 
37 fathoms ; those described by d’Orbigny were found in shore-sands from Cuba and 
Jamaica.

Miliolina cultrata, Brady, 1881, Quart. Journ. Micr. Sci., vol. xxi., N. S. p. 45. 
Test Triloculine, depressed; segments long, narrow, biconvex; superior end of the 
final chamber projecting far beyond the base of the penultimate ; peripheral margin fur- 
nished with a continuous narrow keel or wing. Length, ^tli inch (0'8 mm.). 
Miliolina cultrata is a thin feeble form with conspicuous marginal keel. The figured 
specimens are from Humboldt Bay, Papua, 37 fathoms. Some fine examples, many of 
them rather more broadly built than these, have been found in sand dredged by Mr. A. 
Haly, off Calpentyn, Ceylon, 2 fathoms. I am not aware of any other locality for the 
species. 
Miliolina valvular is , Reuss, sp. (PI. IV. figs. 4, 5).

I have adopted Reuss’s name for some striking Triloculine Miliolce dredged off the 
coast of New Zealand. They agree accurately in general characters with the engravings 
referred to in the memoir on the Foraminifera of the Septaria-clays of the neighbour- 
hood of Berlin, and differ only in the shape of the mouth, which, instead of being 
a semicircular slit, is long and irregularly bent, the lips puckered and closely drawn 
together. The test is large, some of the specimens being more than ^th inch (2 '5 mm.) in 
length, and very compactly built ; the inner marginal edges of the chambers thin out and 
embrace the adjoining segments. The disposition of the segments and the unusual 
thickness of the shell -wall are well shown in the section (fig. 5). The species is one 
of the few that may rank with Miliolina trigonula and Miliolina tricarinata as a 
true Triloculina. 
The Challenger specimens are from Station 168, north-east coast of New Zealand, 
depth 1100 fathoms. 
The fossil examples figured by Reuss and by Bornemann are from the Tertiary 
Septaria-clays of Hermsdorf, near Berlin.
