174 EOCENE AND LOWER OLIGOCENE CORAL FAUNAS. 



Balanophyllia annularis Sp. IIOV. 

 PI. XX, figs. 3 to 5. 



Shape of corallum subcorneal, rather sliort, usually slightly curved, 

 transverse outline elliptical; attached by a small base. Costpe small, cor- 

 responding to all cycles of septa; beautifully granulate. Usually there is a 

 single row of granules on the costse corresponding to the third, fourth, and 

 fifth cycles of septa, but occasionally it may be double. The costai corre- 

 sponding to the first and second cycles are much wider than those correspond- 

 ing to the higher cycles, which are equal in size; the former are rather 

 flattened above, while the latter are acute. The epitheca is usually well 

 developed, extending rather far up the side of the corallum. Since it is 

 thicker in some places than in others, it gives to the corallum an annulated 

 appearance. The wall in its upper portion is rather thin but dense for a 

 Balanophyllia, the corallum filling up internally by secondary thickening. 

 Septal aiTangement typical for the genus in five cycles; their sides 

 granulate. Dissepiments absent. Columella vesiculate, weak. The follow- 

 ing measurements are from an average specimen: Greater diameter of 

 calice, 11. .5 nun.; lesser diameter of calice, 10 nun.; height of corallum, 

 17 mm.

This species stands alone among our Eocene Balanophyllipe ; iio other 

 one possesses such a dense, highly developed, annulated epitheca. It has 

 a gross resemblance to some .specimens of B. irrorata var. coniformis, Init 

 the two forms could scarcely be confused. Occasional specimens lack tlie 

 epitheca. These resemble Eupsammia elaborata (Conrad), to be described 

 later. B. annularis, in all the well-preserved specimens that I have seen, has 

 a very small nipple-like pedicel, or a sear of attachment. The corallum is 

 more compact than in Eupsanmila elaborata. 



Balanophyllia augustinensis sp. nov. 



PI. XX, figs. 6 to 10. 



Form slender, elongate cornute, cross section elliptical, base pointed, 

 attached by a very small pedicel. Costaj subequal in size, low, broad, granu- 

 lar. In lower part of corallum frequently composed of simply one row of
