irregular and numerous, and are in sets of three or of five between two larger ones. 

 There are five cycles of them, and a few members of a sixth. 



The epitheca is delicate, and forms an integral part of the costal arrangement.

The corallum is greatly compressed, and is deltoid, wedge-shaped, or flabellate in 

 outline. There is usually a curved pedicel with a mark of former adhesion, but in 

 some the pedicel is straight and sharp. The long, elliptical, rather pointed-ended, and 

 sometimes sinuous calice is usually on a level plane, but sometimes not. It is rather 

 deep centrally, stout at the margin, and crowded with septa. 



The costse are distinct near the calice, and subequal there, slightly projecting, 

 granular, and have small intercostal spaces. Lower down, the costse become alternately 

 large and small, the smaller being rather linear in some instances. They merge into a 

 pellicular epitheca, or into a " broken " epitheca consisting of irregular-shaped pieces 

 resembling a bad mosaic. 



The septa are slightly exsert at the margin, curved above and not dentate. They 

 are crowded, and there are five cycles, with extra orders in large specimens. They are 

 alternately large and small, long and short. The longer gain the axial space and bound 

 it. All are distinctly and largely granular. 



There is no columella. The endotheca is scanty. There is a slight exotheca here 

 and there. 



The height of the largest specimen is i^inch, and its calice is in length 1^% inch. 

 The next specimen is j^ inch high, and about an inch in length. A third, drawn on 

 Plate III, is j^ inch high and ^^ inch long at the calice.
