often rises into a slight, denticulated palifonn lobe, before joining the 

 columella processes ; the secondaries are similar, in adult corallites, but 

 are cousideral^ly narrower and only rise about two thirds as high 

 above the margin of the wall ; the tertiaries are strongly denticulate 

 and very thin, narrow in their upper part, and project but slightly 

 above the wall, Init the basal portion is broad and usually joins the 

 columella, or unites with the secondaries before reaching it ; those of 

 the fourth cycle, and of the fifth when present, are very thin and 

 narrow, scarcely exsert, exteriorly usually united laterally to those of 

 the ])rincipal cycles, with the inner edges sometimes united to the 

 tertiaries. All the septa have their sides covered with sharp granula- 

 tions. Columella often rudimentary, while in other corallites of the 

 same cluster it is pretty well developed, though occupying a small 

 area (usually less than a fourth of the diameter of the calicle), it is 

 composed of coarse, rough, contorted processes, originating from the 

 inner edges of the septa, with irregular openings and a rough uneven 

 surface.

Coralla, so far as observed, simple, consisting of solitary corallites 

 distantly scattered over dead shells, stones, etc., without any apparent 

 connection, or entirely isolated. The corallites are low, broad, sub- 

 circular, and unusually large for the family. The calicles are mod- 

 erately deep, or shallow, with a broad bottom occupied by a well- 

 developed papillose columella. Septa numerous, usually in five com- 

 plete cycles, unequal, all with sharply granulous sides, with the inner 

 portion divided into numerous small prominent teeth, which blend 

 with the papillae of the columella. The primary and secondary septa 

 are much broader and more elevated in their outer part, with broadly 

 rounded summits, which are usually subentire, but sometimes incised ; 

 the other septa are all strongly denticulate at summit ; those of the 

 last cycle very narrow and thin. The wall is covered at base with an 

 imperfect epitheca and usually much encrusted with Bryozoa, Nulli- 

 pora, etc. ; above this it is naked and more or less costate. The 

 transverse dissepiments are few and oblique, close to the base.
