columella. Their edge is entire, the sides are covered with granules which are often arranged the 

 in rows perpendicular to the edge and in rows parallel to the edge. Striae parallel to the edge 

 are often visible. The outer septa of the fifth cycle are broader than those of the fourth and 

 third cycle and nearly as broad as those of the first two cycles. The edge of the septa of the 

 higher cycles is entire or toothed, and the sides are densely covered with granulations. 



The columella is trabecular, projecting, its length about half that of the calicle. In one 

 calicle the septa meet in the centrum leaving no room for the columella. The depth of the 

 calicle is about i cm.. 



2. Balanophyllia fistiila Alcock. 



Balanophyllia (Thecopsammia) fistala Alcock 1902. 

 Thecopsammia fistula v. Marenzeller 1907b. 



Stat. Si. Puin Sebangkatan, Borneo-bank. Depth 34 meter. 1 ex. 



Stat. 260. 2.3 miles N., 63 W. from the North point of Nuhu Jaan, Kei-islands. Depth 



90 meter. 3 ex. 

 Stat. 310. S°3o'S., ii9°7'.sE. Sapeh-strait. Depth y^ meter. 1 ex. 



Von Marenzeller correctly identified this species, of which Alcock gave a rather short 

 description. The accurate description of v. Marenzeller wholly agrees with the type-specimen. 



3. Balanophyllia rediviva Mos. 



Balanophyllia rediviva Moseley 1881. 

 Balanophyllia rediviva v. Marenzeller 1907 b. 



Stat. 260. 2.3 miles N., 63 W. from the North-point of Nuhu Jaan, Kei-islands. Depth 

 90 meter. 2 ex. 



These specimens wholly agree with the description and figures of Moseley and Marenzeller. 



4. Balanophyllia cornucopia (Pourt.). (Plate VIII, fig. 13). 



■Dendrophyllia cornucopia Pourtalès 1871. 

 Dendrophyllia cornucopia Pourtalès 1S80. 



Stat. 204. Between islands of Wowoni and Buton; Northern entrance of Buton-strait. Depth 

 from 75 to 94 meter. 1 ex. 



This species was described by Pourtalès from Key-West. My specimen agrees in all 

 respects with bis description. This species is not a Dendrophyllia but a Balanophyllia with 

 buds. My specimen has only one bucl. 



v 5. Balanophyllia nouhiiysi nov. spec. (Plate VIII, fig. 16). 



East-coast of Sumatra., East from Segli. Depth about 100 meter. Van NOUHUYS leg. 1 ex. 



Corallum cylindrical, attached with a spreading base. As is shown in the figure the 

 corallum is Y-shaped, with two corallites. In this respect it should be a Dendrophyllia. Bat as 

 the corallites do not show the slightest tendency to fork or bud again, I think it is an accident.
