eS a 
Orbitoides martini sp. noy. PI. LV, figs. 6, 7, and 9. 
Specimen with edges somewhat broken. Dise-shaped, with slight protuberance 
in the center; often found bent and warped, rarely perfect. Surface perfectly 
smooth. Section (fig. 9) shows no central chambers larger than usual, as is 
the case in some species of orbitoides. Chambers in the median line lozenge- 
shaped and with their long axes at right angles to those of the chambers in the 
outer cycles. Diameter of individuals varies from 15 to 50 millimeters. 
Locality: Limestone on Loboo River, Batangas Province. 
Age: Younger Miocene. 
Similar forms are plentiful in the limestones of Cebu, above the 
Coal Measures. 
GASTEROPODA. 
TURBO Linn.

and 4, p. 11. 
These are casts of individuals which are almost identical with those figured by 
Béttger, though they are a trifle smaller. Height, 15 millimeters; diameter of 
bottom whorl, 25 millimeters. These casts are very abundant both in Batangas 
Province and in Cebu. 
Locality: Limestone on Loboo River, Batangas Province. 
Age: Younger Miocene in the Philippines, though it is found in the Eocene in 
Borneo. 
Fig. 11, Plate IV, is probably a young specimen of this same species. 
NERITA Linn. 
Nerita punctata sp. nov. Pl. IV, fig. 8. 
Thick ovoid, or semiglobose, imperforate. Surface marked by rows of small 
nodes which are arranged perpendicular to the lines of growth. The figure on 
Plate IV shows this specimen at natural size. 
Locality: Limestone on Loboo River, Batangas Province. 
Age: Younger Miocene, 
DRILLIA Gray. 
Drillia (7%) (Pleurotoma) weberi sp. nov. PI. 1V, fig. 10. 
Imperfect specimen which has been provisionally classified as Drillia from a 
comparison with Drillia allioni Bell, from the Miocene of Baden, Austria. As 
very few of the generic, to say nothing of specific, characters can be made out 
on our specimen, this must remain with an interrogation attached to it. 
CYPRAA Linn. 
Cypraea paniculus? Bttg. (young form). 
Cypraca paniculus Bittger. Die Eociinformation von Borneo, Pl. 1/1, 
fig. 23, p. 22. , 
Fig. 12 shows the size of this specimen, which is probably the young of paniculus. 
Locality: Limestone on Loboo River, Batangas Province, 
Age: Younger Miocene.
