views. 



Corallum simple, short, turbinate, irregularly curved, acute at 

 the base, and irregularly distorted in growth. Epitheca thin, 

 with minute encircling wrinkles, interrupted only by the distor- 

 tions in growth, and showing no trace of seota or dissepiments 

 where unabraded, but if slightly worn, both septa and dissepi- 

 ments are exposed plainly to view. Calyx circular, moderately 

 deep, margin thin, from which the sides gradually slope to near 

 the bottom of the cup, where the septa curve to the central 

 tabuke, and the wall as abruptly thickens. No septal fossula. 

 From twenty-four to fort^' septa extending from one-third to 

 the entire distance from the outer wall to the center. Most of 

 them terminate before reaching half the distance to the center, 

 but a few are shown to reach to the center. Secondary septa 

 quite marginal and best seen when the epitheca is eroded on 

 the outside. The tabulte, as seen in the central area of the 

 calyx, are flat and smooth except where penetrated by the 

 septa. The outer vesicular zone is thin and vesicles rather large. 



Our specimens are only about an inch in length, and we think 

 they represent a small turbinate species. The species evidently 

 belong to this genus, from the vesicular outer zone, incomplete
