There are 41 species of fossil Corals from the Gaj series. 



The forms belong both to ancient and modern genera, and the fauna does not 

 contain any recent species. The absence of so many of the modern genera of the Pacific 

 and Eed Sea, considered with the evident antiquity of many of the genera, indicates 

 a Miocene age. Many of the forms are representative of the West-Indian Miocene. 



Many massive specimens of Corals form a limestone which is saccharoid, and the 

 septa usually are very incomplete ; they usually belong to the great species of 

 Stephanocmnia.
