forms are practically all common to the Upper Miocene of 

 Java according to K. Martin 5 . 



Cerithium jenkinsi is from Martin's locality Z; Cerithium 

 herklotsi and Cerithium bandongensis from his locality O; 

 Conus hardi and Conus striatellus, locality O ; Columbella ban- 

 dongensis, locality O ; Mitra junghnhni and M. javana, locality 

 O; M. jenkinsi, locality K; M. bucciniformis, locality R; 

 Turris coronifer, locality O ; Terebra javana and T. bicincta, 

 locality K ; Vicarya callosa, localities O and P ; Vermetus java- 

 nus, localities I and P. According to Martin, most of these 

 forms are characteristic of the Upper Miocene of Java. 



In a very excellent paper entitled "Concerning Tertiary Fos- 

 sils in the Philippines" by Prof. Karl Martin, there is listed a 

 series of faunas from the Cagayan Valley of northern Luzon 

 which apparently belong to this same horizon. Concerning 

 this series he gives the following discussion : 



"Now, in reviewing Semper's collection, I was at once struck 

 with Vicarya callosa Jenk., which is known from Java and is 

 described in detail below ; and this induced me to make a closer 

 comparison between the fossils of the Philippines and those of 

 the Indian Archipelago, whereby it at once became apparent 

 that a whole series of species, especially of the Javanese Ter- 

 tiary, is common to both regions. Thus far, indeed, I have 

 been unable to make a complete study of Semper's collection, 

 and for the time being it has little further interest, because 

 statements as to stratigraphical position are entirely lacking 

 and the equivalent deposits of neighboring regions are still 

 very insufficiently known. After completion of my monograph 

 on the fossils of Java, however, I hope to undertake a more 

 thorough study of the Philippine fossils, and to supplement this 

 preliminary communication." 



Martin lists the following from Luzon :
