AGE OF THE VIGO GROUP 
In the above list there are 98 forms that are specifically de- 
termined and of these 74, or 75.5 per cent, are living species, an 
astonishing number when the geologic history of the region 
yielding these forms is considered. In addition, the extinct 
forms are practically all common to the upper Miocene of Java, 
according to K. Martin.’ | 
Cerithium jenkinsi ig from Martin’s locality Z; Cerithium 
herklotsi and Cerithium bandongensis, from his locality O; 
Conus hardi and Conus striatellus, locality 0; Columbella ban- 
dongensis, locality O; Mitra junghuhni and Mitra javana, locality 
O; Mitra jenkinsi, locality K; Mitra bucciniformis, locality R; 
Turris coronifer, locality O; Terebra javana and Terebra 
bicinta, locality K; Vicarya callosa, localities O and P; and 
Vermetus javanus, localities I and P. According to Martin, 
most of these forms are characteristic of the upper Miocene of 
Java.
