Plate VIII). Often also the slender base is broken off and regenerated. When the corallum is 

 free the ribs are often worn oft' in the basal portion of the corallum; that is clearly shown by 

 a few Iarger specimens, but when the corallum is attached or young the ribs are conspicuous 

 from the base to the margin. So I do not think that there is any difference between these 

 two species. 



Balanophyllia malaccensis Sav. Kent seems to be a young specimen of the same species. 

 Some of the younger specimens that I could examine quite agree with the description of 

 Saville Kent and the description and ftgure of Balanophyllia floridana Pourtalès, which species 

 is very similar to B. malaccensis according to Saville Kent diftering only in the form of the 

 columella and the granulations on the septa. 



The Balanophyllia gemmifera Klunzinger has a well-developed epitheca, whereas in my 

 specimens the epitheca is usually absent. But I have also specimens with an epitheca, though 

 it is never complete, consisting only of scattered patches. I do not think, that this difference 

 allows a specific separation. 



As is shown in the fïgures the general aspect of the corallum varies a good deal. It 

 is always conical, with a narrow base and a wide top. But it may be very slender and long 

 or blunt and short, it may be curved, sometimes twice or more in different directions, or erect. 

 It may be attached or free; simple or with buds, sometimes of three or four generations. 



The formation of buds is shown by all the specimens from Stat. 289. As many buds 

 had broken off from the parental calicle, the exact number of specimens was not to be 

 determined. The buds are fixed on the wall, sometimes near the base, sometimes near the top, 

 often on the calicular margin, or even on the septa. But I am not quite sure whether they 

 are really buds at all and not oözoites. I found specimens attached to shells, on dead pieces 

 of coral, to the wall and to the calicular margin of a Flabellum exactly in the same way 

 as to the so-called parental calicle. The bottom of Station 289 consists of mud, sand and 

 shells. It is quite possible that the older corallites are a welcome point of support for the 

 attaching oözoites. 



The length ol the corallite is up to 5 cm.. The calicle is elliptical in shape, measuring 

 e. g. 14 X 12 mm. or 16 )< 12 mm.. The ribs are roughly granulated; the principal costae 

 can project a little more than the others. Septa in the older calicles in five incomplete cycles, 

 in younger there are four cycles. Septa of the first and second cycle equal, markedly exsert, 

 spongy at the upper margin, having the edge entire, and granules on the sides. The septa of 

 the higher cycles roughly dentate. Columella well developed, prominent, spongy, it length nearly 

 half that of the calicle. The depth of the calicle is half its length.
