Siphonina sp. ef. species from Oligocene of the United States. 
Pulvinulina sp. ef. species from Oligocene of the United States. 
Asterigerina sp. ef. species from Oligocene of the United States. 
Amphistegina sp. 
Ellipsoidina sp. 
Madreporaria: 
Obicella sp. cf. a species from the lower Miocene of Trinidad and Vieques 
Island. 
Psammocora sp. ef. a species from the Miocene of Trinidad. Other species 
of this genus are known from the lower Miocene of Trinidad, Vieques 
Island, and the Dominican Republic. 
Geologic correlation.—The basis for correlating this deposit is not 
definite, but the horizon seems to be very low Miocene. 
Vieques Island 
At Punta Salinas, east of Port Salinas and Salina del Sur, at the 
east end of the island, and along the south shore from opposite Esper- 
anza to Ensefiada de la Chiba, there is soft, light-colored, usually 
yellowish, bedded, fossiliferous limestone, which although slightly 
tilted and in places flexed, has been, in comparison with the older 
hard blue limestone, only slightly disturbed. Between Ensefiada 
Sombe and Port Mosquito, between Port Mosquito and Port Ferro, 
and on the east side of Port Ferro, steep, northward-facing slopes 
mark the northern edges of the areas of its outcrop. The following 
are the paleontologic determinations for Vieques: 
Station 8652. Vieques Island, north side, east end, the western- 
most of the yellow marl and limestone bluffs at the east end of the 
island.
