A few fossil specimens, rather worn, which are, however, clearly 

 referable to this species. It has been recorded from the London 

 Clay, and many later formations. Our specimens are probably 

 derived from the Tertiary shell sands of the Bognor rocks. '

Rotalia exsculpta Eeuss, 1860, Sitz. k. Akad. Wiss. Wien, vol. xl. p. 222, 

 pi. xi. fig. 4. 



Frequent, and typical specimens of this Cretaceous fossil. 

 Owing to its minute size and the fact that the typical markings 

 are frequently so clogged with chalk as to be indistinguishable, 

 this pretty little form is probably often overlooked. At any rate, 

 there appear to be very few records of its occurrence since Eeuss 

 first described it from the Westphalian chalk. It seems to be 

 pretty generally distributed throughout the chalk, but is apparently 

 confined to that formation. Jones and Parker* consider it closely 

 allied to the Rosalina ornata of d'Orbigny. f
