EOCENE AND LOWEE OLIGOCENE CORAL FAUNAS. 



Vicksburg beds. During the time of the forniatiou of the Red Bluff, the 

 species had not assumed definite characters, but was almost protean. The 

 specimens that are straight and with a basal nipple may be referred to 

 B. caulifera s. s. The variety may be thus characterized: 



Corallum more or less cornute, short or rather long, the curvature not 

 having any invariable relation to the calicinal axes, but usually in the plane 

 of the o-reater axis. The area of attachment extremely variable in size ; 

 sometimes the attachment is by a small pedicel, but in other instances by a 

 considerably expanded base. The costse maj^ be a simple row of acute 

 granulations, or they may be wide, rounded, or flattened in profile and 

 densely and irregularly granulated. The septa and columella need no 

 special description. No dissepiments could he found in the interseptal 

 loculi.

The following is a translation of the descrijjtion in the Annales des 



Sciences Naturelles : 



Specie.s very near to the preceding [E. hayliana). Base umbilicate. GostiB very 

 crowded, composed of very fine, very prominent, and regular grains, which, for the 

 most part, are double in their lower part and trifurcate at a certain height. Colu- 

 mella considerably developed, spongy, but rather dense. Septa very much crowded,
