18, 1 Dickerson: A Fauna of the Vigo Group 18 
In a very excellent paper, entitled “Concerning Tertiary Fos- 
sils in the Philippines,” Prof. Karl Martin listed a series of 
faunas from the Cagayan Valley of northern’ Luzon which ap- 
parently belong to this same horizon. Concerning these faunas 
he gives the following discussion: 
Now, in reviewing Semper’s collection, I was at once struck with | 
Vicarya callosa Jenkins, 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 Tertiary 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 comple- 
tion 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:
