REPORT OH THE FORAMMFERA.

whilst Hantken’s illustrations are drawn from a specimen in which the sutures are indicated 
by fine lines without superficial limbation. The drawings referred to are all from fossil, 
specimens, but in the living condition the species presents a similar diversity of character 
in these and other particulars. In some cases, as in the figured specimens (PI. XLII. 
figs. 15, 16), the peripheral teeth are more fully developed than in any of the examples 
referred to, but, generally speaking, the recent test accords pretty closely with the 
original description. 
The only Challenger locality at which Textularia carinata has been found is Station 
209, off the Philippine Islands, 95 fathoms, where it is tolerably abundant. Its occurrence 
on the shores of the Adriatic is recorded by d’Orbigny and Parker and Jones. 
The geological range of the species covers almost the whole Tertiary epoch. It has 
been obtained from the Eocene clays of the neighbourhood of London (Parker and Jones, 
Brady), from the Lower and Upper Oligocene, and the Septaria- clays of Germany (Eeuss), 
from the Miocene deposits of Austria (d’Orbigny), of Malta (Brady), and of Calabria 
(Seguenza), and from the Pliocene beds of Italy and elsewhere (d’Orbigny, Reuss).

This is perhaps the commonest of all the TextularicB, whether in the recent or fossil 
condition. The test is elongate and much compressed, and the lateral edges are sharp, 
but the outline varies considerably, owing to the more rapid and more regular increase 
in the size of the segments in some specimens than in others. The walls are generally 
thick and opaque without being distinctly arenaceous. 
Textularia sagittula is a cosmopolitan species, affecting most the shallow water of 
temperate seas ; it has nevertheless been found at depths as great as 2675 fathoms in 
the North Atlantic, and 1425 fathoms in the South Atlantic.
