record it from Borneo and the Loo Cboo Islands, whilst Prof. 

 Rupert Jones and the author identified it in the Miocene lime- 

 stones of Christmas Island. Verbeek iiad it from Java, and it is 

 recorded with some reservation by Lemoine &, R. Douville from 

 certain rocks in Spain. 



(7) Evidence of oscillation of the Miocene shore-line in the 

 neighbourhood of the New Hebrides is afforded by the occurrence 

 of beds largely composed of Glohigerince mixed with fine tuffa- 

 ceous material, in close association with the limestones containing 

 shallow-water reef-forming organisms, but itself must have been 

 formed at some considerable depth, as shown by the vast accumu- 

 lation of the pelagic globigerine shells. 



(8) The two important reef-building agents of foraminiferal 

 origin at the present day, namely Garpenteria rhaphidodendron 

 and Polytrenid planum, are here shown to have undoubtedly 

 performed similar work in Miocene times. 



(9) The Miocene genus Linderina, by its present occurrence, 

 has its range extended farther eastward.
