The appended initials indicate the occurrence of the 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. 

 The strata in the vicinity of Minanga are, according to Martin, 

 essentially the same horizon and he says : "Judging from all 

 these facts, the strata at Minanga are to be classed with the 

 Upper Miocene bed which exists in Java in the locality denoted 

 by Junghuhn by O, and at Selatjan on the Tjilongan." As was 

 indicated above, many of the fossils from the Bondoc Penin- 

 sula are common to this locality O in Java, and the equivalence 

 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, Cyloclypeus com- 

 munis Martin, from his (and Junghuhn's) localities K, L, O 

 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
