TABLE OF DISTRIBUTION.

St. Eeth Beds. — The column referring to the St. Erth Beds is prepared from the lists published 

 by Mr. Fortescue W. Millett in his papers (1SS5, 1894, &c.) already quoted {antea, p. 80), supplemented 

 by notes of additional species kindly supplied to us by Mr. Millett, who has further added to our 

 obligations to him by very kindly furnishing the records of " size " and " frequency " of the species met 

 with in this rich deposit. Mr. Millett wishes us to state that, although Lagena Lyellii remains in the 

 St. Erth list in this Table, he is of opinion that it should probably be omitted as not being a good 

 " species." 



Belgian Pliocene. — The records for the Scaldisian and Casterliau Beds are the result of our 

 examination of material selected by one of us in company with M. E. Vanden Broeck during the 

 summer of 1886, at which time the excavations for the dry docks at Kattendyk, Antwerp, were in 

 progress. The Scaldisian fossiliferous beds were divided by M. Vanden Broeck into two principal 

 bands, a "banc coquillier inferieur " and a "banc coquillier superieur." The difference between 

 the Foraminifera obtained from these bands is inconsiderable, and we have therefore given but one 

 column for the two bands. 



The Diestian (of Edeghem) list is prepared from that published by M. Mourlon (' Geol. de la 

 Belgique (1880), vol. ii, pp. 235 et seq.). The list is an old one founded on that by H. Nyst in 

 Dewalque's ' Prodrome d'une description geol. de la Belgique ' (1868), which again appears to be 

 based upon Eeuss's work on the Crag of Antwerp. We have carefully examined the published 

 figures and descriptions, and have referred the species recorded to their synonymic position wherever 

 practicable. A few still included in the list under the names given by Eeuss are doubtful species. 



Italian Pliocene. — The Foraminifera of the Plaisancian Beds of Bordighera and Albenga, here 

 recorded for the first time, were obtained from material kindly supplied to us by Mr. Edward
