This species is moderately common in the Philippine coal measure shales, 
being especially plentiful in the shale above the principal coal seam on 
the eastern end of Batan Island, Albay Province. It is also found in the 
same position in the coal measures in Cebu and Mindanao. 
On this account it seems to the writer that the above reference 
to the Oligocene is very questionable, and it is his opinion that this 
Batan coal is of essentially the same age as is the coal of Cebu 
and tunnel 14 of Sibuguey Peninsula, Mindanao. At the latter 
place, Mr. F. A. Dalburg recently collected splendid specimens of 
Vicarya callosa Jenkins from the coal seams and shales. (See 
Plate 6, fig. 1a.) Now Vicarya callosa is associated with the coal 
seams of Cebu and seems to be a form which flourished in brack- 
ish water. Whether this form is very limited in geologic range 
is probably open to question, as those forms which have a great 
geographic distribution frequently have a considerable strati- 
graphic range as well. It is probably limited to the Vigo group 
at least, that is, to about 3,000 feet of sedimentary beds, as it 
never has been reported from the Malumbang formation. 
Douvillé places locality 272 in his II, 2, the Lepidocyclina 
limestone. The Bureau of Science possesses an excellent collec- 
tion of gastropods and pelecypods from this place, and the 
following forms have been identified: 
Bullaria ampulla (Linneus). Pecten cf. lentiginosus Reeve. 
Conus sp. Pecten leopardus Reeve. 
Cerithium (Campanile) sp. Plicatula imbricata Menke. 
Cerithium sp. Turbinella junghuhni K. Mar- 
Cerithium jenkinsi K. Martin. ‘tin. 
Cerithium herklotsi K. Martin. Trochus sp. 
Cypraea sp. Turbo sp. a. 
Chione lacerata Hanley. Seraphs sp. 
Fusinus sp. Vicarya callosa Jenkins. 
Natica sp. Voluta innexa Reeve. 
Lucina sp. 
A brief comparison of these forms with collections from the 
Vigo group of Bondoc Peninsula clearly demonstrates essential 
faunal unity. 
W. D. Smith ** reported some of the large foraminifers from 
Bondoc Peninsula from beds of Canguinsa age. He says: 
The limestone from Mount Morabi (fossil locality 62) contains Cyclo- 
clypeus communis K. Martin, which represents the middle Miocene, and 
large lepidocyclinas some of which are 45 millimeters in diameter and 5
