The height of the corallum is | cm., both corallites have the same height. The cormnon stem 

 has a diametei mm . the separate corallites ol 7 mm 



\ thin, porous epitheca extends from the base to about 1.5 cm. from the upper margin. 

 The ribs are narrow, but apparent from the top to the base. In the basal part of the corallum 

 : »vered bj one or more rows of fine pointed granules. In the upper part above the 



epitheca the ril>s. are cd by larger and verj irregular granules, and the wal! is much 



perforati principal costae corresponding with the septa ol the firsl (\<1<- are prominent. 



The ire arranged in four complete cycles. The septa of the lirst order are much 



2 mm. above the margin <>!" the caliele, those of the second cycle project 



nm.; the projecting part of the septa is spongy, otherwise they are thin. The septa slope 

 down, till they projeel about one third ol the diameter of the caliele. then fall perpendicularly 



irds the bottom. The septa of the second cycle are narrower than those of the lirst one 

 The edge is entire; nearly no granules on the faces. Septa of the fourth cycle broader than 



■ of the third, joining in front of the latter near the columella. The edge of these septa 

 is provided with small teeth. Columella well developed, very prominent, trabecular, 3 mm. long. 

 The diameter of the elliptical calicles is 8 < 7 and 7 < 6 mm. and their depth about 4 mm.

I have good reasons lor the above given synonymy of this species. The Balanophyllia 

 mentioned by Alcock in [902 from Stat. 297 of the Siboga Expedition is not a true 

 Balanophyllia cornu. According to Moseley's description the septa are in B. cornu very slightly 

 exsert, the wall very finely perforated and the costae composed of line but sharp granules. In 

 all these characters this specimen of tin- Sibo ;a I :pedition does not agree with the description, 

 but it at^rees in all respects with my spe< imens as is shown in tin? figure. 



The only differences in the descriptions of Balanophyllia imperialis Sav. kent and 



Eupsammia regalis Alcock are that the first mentioned is attached by a slender l>asr and has 



ribs conspicuous from the base to the margin, and tin- latter is free from traces ol former 



:i and the 1 re distinci in the uppi r two thirds of the corallum. Now my specimens 



1 to small shells, and pieces of coral, often also on the corallum of the sami 



. The original support is often very small. and 1>\ continued growth it is wholly 



i basal portion of the corallum. which is then apparently free see fig. 28and 20 on
