REPORT ON THE FORAMINIFERA.

are depressed at both umbilici (fig. 3), others are umbonate at one or both (fig. 2) ; 
sometimes the earlier convolutions are visible to a nearly equal extent on both faces ; some- 
times, on the other hand, they are nearly involute on the inferior side, though the shell 
retains its bilateral symmetry, as in Reuss’s figure. The coarse perforation of the shell- 
wall is usually more conspicuous on the inferior than on the superior face. 
Good recent examples of Anomalina ammonoicles were taken at a single Station 
in the North Atlantic, off Bermuda, 435 fathoms; but with this exception, so far 
as the Challenger collections are concerned, the record of its occurrence is limited to the 
South Pacific. The list comprises two localities near the Fiji Islands, depth 210 and 
1350 fathoms respectively; another oft’ the west coast of New Zealand, 275 fathoms; and 
a fourth in Humboldt Bay, Papua, 37 fathoms. It has been observed by Parker and 
Jones in soundings from the Red Sea, 372 to 678 fathoms; in anchor-muds from 
Bombay and Hong Kong, in shore sands from Melbourne; and in material from the 
Abrolhos Bank, 260 to 940 fathoms. The Rotalina lamarckiana of d’Orbigny (Foram. 
Canaries, p. 131, pi. ii. figs. 13-15), which was obtained from sand collected on the shores 
of Teneriffe, is scarcely separable from the present species. 
In the fossil condition it is common throughout the Cretaceous system ; it is met 
with again in the London Clay, and identical or very closely allied forms occur in 
microzoic formations of almost every subsequent geological age.

The test of this species presents a smaller number of chambers in each convolution 
than that of its near ally Anomalina ammonoides ; it is also relatively thicker and less 
regularly built. The walls are coarsely perforated, but have fewer pores on the superior 
than on the inferior side. 
Recent specimens of Anomalina grosserugosa have been obtained at four Stations in 
the North Atlantic, the depths ranging from 450 to 1000 fathoms ; at three Stations in 
the South Atlantic, 420 to 1415 fathoms; at two in the South Pacific, 610 and 2160 
fathoms ; and at two in the North Pacific, 345 and 2050 fathoms respectively. 
As a fossil the form occurs in the Eocene of the Bavarian Alps (Gumbel), and of the 
London Basin (Brady) ; and in the Clavulina-szaboi formation of Hungary (Hantken). 
D’Orbigny figures a very similar variety from the Miocene of Baden, near Vienna, under 
the name Anomalina badenensis (For. Foss. Vien., p. 171, pi. x. figs. 1-3).
