Septa arranged in five incomplete cycles. Those of the first cycle slightly projecting 

 above the calicular margin ; they are rounded at the top which is spongy ; the inner edge falls 

 perpendicularly towards the columella. The edge is entire or with minute teeth, the sides are 

 covered with oranules. The septa of the second cycle are a little smaller than those of the first 

 one, but have the same aspect. The septa of the higher cycles are dentate on the edge. Those 

 of the fourth cycle join in pairs in front of those of the third cycle. The septa of the fifth 

 cycle are very small. 



No paliform lobes. Columella well developed, spongy. It measures 5X3 mm. in a calicle 

 with a diameter of 1 1 >< 9 mm. The depth of the calicle is about 5 mm. 



Broken off calicles are not to be recognized from a Balanophyllia. The two specimens 

 of Stat. 220 are broken off calicles, but one of them shows clearly the stumps of the stolons.

 Stat. 279. Ruma-Kuda-bay, Roma-island. Depth 36 meter. 1 ex. 



I have before me a large colony consisting of a great number of corallites incrusting 

 an irreofular rough stone. The stolons, which spread over the surface of the stone in every 

 direction consist of a trabecular network; they are not covered by ribs. The breadth of the 

 stolon-like expansions is very variable, from one to five mm. The distance between the separate 

 calicles is also very variable, they may touch one another or there may be a distance of 

 one cm. between them. 



The corallites are small, not projecting more than two mm. above the base; they are 

 cylindrical or a little tapering towards the top; their round calicle has a diameter of 5 mm. at 

 most but usually less. Some of the corallites, and these are usually the smaller ones, are 

 covered by a dense epitheca from the base to the calicular margin, in others only the basal 

 part of the wall is covered by an epitheca; the uncovered upper portion may be one mm. or 

 even two mm. long. The ribs are broad and flat, they may be smooth or covered by a few 

 small, blunt granules. The small perforations of the wall are restricted to the furrows. 



The septa are arranged in four cycles which are usually incomplete. There may be a 

 fifth cycle in a few systems of the largest calicles. The septa are exsert. Those of the first 

 and second cycle are a little broader than the others near the calicular margin. The edge of 

 the projecting part of the septa makes a curve of half a circle, than the septa slope gradually 

 to the interior. As the septa are rather narrow near the top and all about of the same breadth 

 the calicular fossa is regularly funnel-shaped. All the septa have teeth on the edge and are 

 densely granulated on the sides, they are equally thin and nowhere spongy. The septa of the 

 third cycle are short, those of the fourth cycle unite in pairs in front of those of the third 

 cycle. In the smaller calicles also the septa of the second cycle do not reach the columella. 



No paliform lobes. The columella is concave, trabecular, its length being about one-third 

 that of the calicle. Most of the calicles are very deep, their depth equaling their diameter. 

 Other calicles are not so deep.
