DESCRIPTIONS OF SPECIES.

gi-auules, while in- the upper portion there may be as many as three along- 

 side one another. When there is more than a single row of granules, the 

 granules are arranged irregularly. Shape and character of the costse distin- 

 guish the species. Wall originally regularly perforate, but becomes second- 

 arily compact below the calice. The presence of epitheca is doubtful; on 

 the best-preserved sjjecimens there is none. 



The septa have the typical Balanophyllid an-angement. In the smaller 

 coralla there are five complete cycles. Those of the fifth fuse in front of the 

 fourth, and by a prolongation from place of fusion to the columella or to 

 the sides of the third. They appear to be thin originally, but become sec- 

 ondarily thickened and completely fill the lower portion of the corallite 

 cavity. The septal faces are beset with rather tall, pointed granulations. 

 The granulations are frequently inclined. There is no system about the direc- 

 tion of the inclination; sometimes they point outward, sometimes inward. 

 No dissepiments could be found. The columella is not very large; it has a 

 papillate upper surface.

Balanophyllia elongata sp. nov. 



PI. XX, flgs. 11 to 14. 



Form of corallum elongate conical, slightly curved, the curvature not 

 having special reference to the planes containing the longer or shorter 

 transverse axis of the calice. Attached by a veiy small base. Costae 

 distinct, granular, flat, not very prominent, those corresjionding to the first 

 and second cycles of septa stronger than those corresponding to the third 

 and fourth cycles. Epitheca thin ; reaches high up the sides of the corallum,
