The appended initials indicate the occurrence of tlje species 
in the Tertiary of other parts of the Indian Archipelago, as 
well as among the fauna of the present day. Thus E denotes 
Eocene; M, Miocene; P, Pliocene; J, later Tertiary in general; 
Q, Quaternary; L, living species. 
The fossils in Martin’s list come from nine different localities 
and the largest number of species from any one locality is ten. 
According to Martin, the strata in the vicinity of Minanga 
belong essentially to the same horizon, and he says : 
Judging from these facts, the strata of Minanga are to be classed with 
the upper Miocene bed which exists in Java in the locality denoted by 
Junghuhn by O and at Selatajan on the Tjilongan. 
As was indicated above, many of the fossils from the Bondoc 
Peninsula are common to this locality 0 in Java, and the equiv- 
alence of the Upper Vigo beds with these Javan beds is evident. 
Upon the basis of Martin’s work, the age of the Vigo beds is 
upper Miocene. 
Martin lists the distinctive foraminifera, Cycloclypeus com- 
munis Martin from his (and Junghuhn’s) localities K, L, 0, 
and P.; Orbitoides gigantea Martin is from locality L; and 0. 
radiata Martin is from locality K. These localities all represent 
about the same horizon in Java and it is important to note these 
forms here, as they are regarded as excellent horizon determiners. 
Dr. W. D. Smith, 8 on the strength of the occurrence of Cyclo- 
clypeus communis K. Martin and Lepidocyclina richthofeni Smith, 
refers the Canguinsa sandstone to the middle or lower Miocene. 
His exact statement is as follows : 
* * * The limestone from Mount Morabi * * * contains Cyclo- 
clypeus communis K. Martin, which represents the middle Miocene, and 
large lepidocyclinas some of which are 45 millimeters in diameter and 5
