An interesting discovery in this fragment of limestone from 
Anse an Don]) was that of remains of Foraminifera. The 
porous surface of the shells is not so well seen as in the speci- 
mens from the Protolenus Zone in New Brunswick, but the forms 
are quite similar. Orbulina cf.. universa is the most common, 
but other species of Orbulina, of larger size are present. Other 
species have more than one chamber and so fall into Globigerina, 
and are similar in form and size to those in New Brunswick; 
one shows two chambers, arranged like those of G. turrit a. In a 
number of the globular forms a depression is found on one side, 
perhaps marking the orifice of the shell. 
The shells of these Foraminifera are in most cases injected 
with phosphate of lime, which has preserved their form, and by 
its dark color in contrast to the lighter limestone, causes them to 
stand out on the surface of the layers like minute black seed. 
The shells of the Foraminifera, though generally promiscu- 
ously scattered, in some cases seem to be aggregated near the 
HyOlithoid shells which also are filled with phosphate of lime.
