Summary:
The La (El) Reves Member of the Coamo Formation, here named, consists of thin-bedded sandstone, calcirudite, and limestone conglomerate with lenses of crystalline limestone. Overlies the Botijas Limestone Member; lies 500 m below the top of the Coamo. Thickness ranges from 30 to 250 m. Age is Maastrichtian. [Author intended the name to be La Reves, but map was printed El Reves by mistake.]

Summary:
The name La (El) Reves is here shortened to Reves Member and is reassigned from the Coamo to the Pozas Formation because mapping in the Orocovis quadrangle has shown that the Pozas Formation of the Ciales quadrangle is continuous with the so-called Coamo Formation of the Barranquitas quadrangle; therefore rocks in the northwest Barranquitas are reassigned to the Pozas.
