THE FOSSIL FORAMINIFERA. 
1 1 
T. 7ingeriana has a wide geographical and bathymetrical range in the recent 
condition. As a fossil it has been recorded from the Cretaceous beds and from 
most subsequent deposits. Several specimens rather poorly preserved occur in the 
material from the Pecten-conglomerate . 
Genus Rotalia, Lamarck, 1804. Test spiral, turbinoid; finely porous; aperture 
an arched slit on the inferior face of the terminal segment; surface smooth or 
tuberculate. 
Rotalia beccarii, (Linné). 
Plate II. Figs. 11 and 12. 
Maniiliis beccarii, Linné, 1767, Syst. Nat., p. 1,162, N:o 275. 
Rotalia beccarii, Bkady, 1884. Rep. Chall., p. 704, pi. CVII, figs 2 and 3. 
Test composed of four or five convolutions. Superior (spiral) surface more or 
less convex; inferior convex or flattened. All the chambers visible on the spiral 
surface, only those of the last convolution visible on the lower surface. Septal 
lines distinct. Central portion of lower surface obscured by granulations. 
Rotalia beccarii is a shallow water form though occasional specimens are met 
with in recent seas at considerable depths. In the fossil condition it has been re- 
corded from the Jurassic formation and from most subsequent deposits. It is of very 
frequent occurrence in Tertiary and Post-Tertiary strata. 
In the material from the Pecten-conglomerate it is rather common.
