cursory study of this collection it is apparent that several of 
the species are identical with the reef corals collected from 
the Malumbang Pliocene at its type locality in the Bondoc 
Peninsula. 
Concerning the coralline limestones of this general region, 
von Drasche says: *" 
There can be no doubt that the coralline limestones belong to the most 
recent rocks occurring in northern Luzon. They always form the upper- 
most member of all formations, and with the exception of Benguet, where 
they are covered with a thin layer of red earth, I failed to find these 
limestones beneath other rocks. As has been said,’they contain a number 
of coral fragments which, unfortunately, are in a poor state of preserva- 
tion; they contain, although only in limited numbers, remains of lamelli- 
branchs, gastropods, echinoderms, ete. All of these fossils have, however, 
suffered very much on account of the crystallization of the limestone. 
A more extensive examination of the same material undertaken by me 
in conjunction with my honored friend Doctor von Marenzeller, in charge 
of the collection of the Zodlogical Court Cabinet, led also to substantially 
the same results. : 
Even though it was impossible to give a reliable specific report on ac- 
count of the poor state of preservation of the fossils, it nevertheless was 
possible for us to declare with certainty that, with the exception of one 
single piece, which we could not identify, all of the rest belonged to genera 
which occur to-day in great abundance in the Indian Ocean, and even the 
individual corals can be referred without any question to living types. The 
corals examined do not show the least relationship to the Tertiary corals 
from Java described by Reuss. 
Regarded from this point of view, the raised coral reefs of Luzon must 
be considered as very recent in origin. 
The genera identified by us are the following: Galaxaea sp., Favia sp., 
Maeandrina sp., Porites 2 sp., (?) Astraeopora sp. 
The stratigraphic as well as the paleontologic results go to 
show that the raised coral reefs of Luzon belong to the most 
recent geologic formation. 
Stratigraphic confirmation of the paleontological correlation 
of the Mount Mirador limestone with the Malumbang forma- 
tion was recently obtained by Mr. H. P. Whitmarsh, who 
collected excellent specimens of Vicarya callosa Jenkins, 4 
species characteristic of the Vigo group of Miocene age, from 
sandstones, lignites, shales, and shaly limestones which dip at 
an angle of 35° beneath the coralline limestones of Mount Mi- 
rador belt. This locality is about 6 kilometers west of Baguio 
and about 450 meters south of the Naguilian road which runs
