MR. E. J. LECHMERE GUPPY ON THE 



§ 5. The Foeaminiferal FAUiirA. 



In determining the foraminifera Mr. C. Davies Sherborn, F.G.S., 

 was good enough to offer me his assistance, and ho began the 

 examination of my specimens. But unfortunately his sight became 

 affected, and I was thus thrown back upon my own resources. But I 

 have since had the help of Mr. Joseph Wright, F.G.S., of Belfast, and, 

 thanks to his aid in the correction of names and the identification 

 of forms, I trust that errors are not numerous in the lists which 

 follow. Although Mr. Wright assisted me in the naming of the 

 foraminifera, I am solely responsible for the lists. 



Notes and observations are appended to the lists. The relative 

 frequency of occurrence of the different forms is expressed by the 

 appended letters as follows : — 



I 



signifies that from 1 to 5 



specimens 



have been obtained.

These indications must be taken as applicable only to the whole 

 series of beds comprised under each division of the list, especially 

 as regards the Glohigerina-heds. Certain species are only found 

 in particular beds. Bigenerina, Glandulina^ and Polymorphina 

 are wanting in several beds. Miliolina may be said to be abundant 

 in one bed only, while in another scarcely anything but Glohigerina 

 is to be found.
