to whicli it bears great reseml)laiice. The fmdier development of 

 these buds resembles that of llie buds of au anthocorinus. 



With the exception of the five specimens that were brought back 

 in December 1921, the othei' Fungiae remained on the reef during 

 nearly nine months. On the 2'"' of September, wiien the experiment 

 liad been going on for more than a twelvemonth, the specimens 

 that could still be found, were collected. The putty was still in the 

 central part of the oral surface; in the majority of cases the form 

 was unaltered. 



In most corals at least some part of the oral surface had lost its 

 living tissue, in a few cases only the plug of putty had caused 

 little or hardly any change. The aspect of the Fungiae was now 

 as follows: 



Nos. 507. 510, 519 and 520. The aspect of the corals was very normal, 

 without defunct parts. No budding. 



N". 518. Living tissue normal. The central parts of some septa have risen and 

 have longer dentations. This is owing to the occurrence of new mouths by the 

 side of the old mouth, as was easy to see in the two following specimens. 



N". 509. No parts of the living tissue destroyed. The central extremities of 

 many septa have grown higher in those places which were in contact with the 

 putty and new mouths have been developed beside these elevations of the septa. 

 The new mouths are now entirely surrounded by septa ; on the one side by long 

 regular ones (the original septa of the parent-coral) on the other side by higher 

 parts of recent origin. These parts are somewhat irregular in shape; also the 

 dentations are longer than those of the original septa. 



N». 508. Covered all over with living tissue. On either side of the old mouth- 

 fissure a few young buds had developed, whose mouths lay between the normal 

 longer parts of the septa and the higher irregular parts that originated later on. 

 (Fig. 5). This specimen is very much like N". 509, in which the young septa 

 between the new mouths and the putty are also provided with long dentations. 



N". 521. Few alterations. The living tissue has disappeared only from the 

 central parts of some contiguous septa. Budding is absent. 



N". 512. Some adjacent septa devoid of living tissue, further no alterations. No 

 budding. 



N". 506. Upper surface with two defunct parts, the larger of which covers 

 nearly one tifth of the surface ; the smaller part is a narrow streak from the 

 mouth to the margin of the coral. The larger part of destroyed tissue overlaps 

 the margin and covers a small portion of the under surface. At tbe margin two 

 stemmed young buds have taken origin. The diameter of the disc is respectively 

 2,5 en 3 m.m. In the defunct part on the under surface there are a few smaller buds. 



N'^ 601. Almost half of the upper surface defunct, just as a smaller part of the 

 under surface, especially the margin under the destroyed portion of the upper sur- 

 face. On the boundary between the living and the destroyed part of the under 

 surface, five buds have developed still completely encircled by living tissue of the 

 mother-coral. They are very regular and distinctly stemmed. The diameter of the 

 disc, which in all of them is already broader than the stem, amounts to 6, 7.5,
