Expedition to the Kei Islands at my disposal, and who also arranged 
during this expedition that much time was devoted to the collect- 
ing of certain corals which I wanted in large quantities, e. g. the 
Fungiae of the pafd/a-group. Besides this material Dr. Morten¬ 
sen also sent me the corals from his Pacific Expedition (1914— 
16) and other Madreporaria from the Copenhagen Zoological Mu¬ 
seum to be worked out in connection with the corals from the 
Expedition to the Kei Islands. 
A large number of specimens were lent to me for comparative 
study by Dr. L. F. de Beaufort (Zoologisch Museum, Amster¬ 
dam), Prof. E. D. van Oort (’s Rijks Museum van Natuurlijke 
Historie, Leyden.), Mr. C. Forster Cooper (Zoological Museum, 
Cambridge, England), and Prof. M. Bedot (Muséum d’Histoire 
Naturelle, Genéve). To Dr. C. J. van der Horst I am indebted 
for much valuable information concerning the material of the Siboga 
Expedition. During a visit to the United States Dr. P. Bartsch 
kindly allowed me to study Dana’s types and other corals in the 
U. S. National Museum in Washington, and supplied me with photo- 
graphs of some specimens. A year ago Dr. C. J. van der Klaauw 
already had sent to me elaborate notes and photographs of Fungia 
crassa Dana from the same Museum. To Mr. S. Henshaw and 
Dr. H. B. Bigelow I owe the opportunity of studying a number 
of Verrill’s types and other corals in the Museum of Compara¬ 
tive Zoology in Cambridge (Mass.). 
I wish to thank all the above-named gentlemen for their help 
which enabled me to identify a great deal of my material with 
more accuracy. 
Fungia Lamarck. 
As already has been proved sufficiently by Dbderlein (1902) 
and Vaughan (1907) there is no reason to separate Cycloseris as 
a distinet genus from Fungia. One of the characteristics by which 
these two could be separated as different genera was found in the 
development of the first cycle of septa: Cycloseris in its youngest 
stage according to Gardiner (1899) has six sepia, Fungia after 
Bourne (1893) twelve. In Bourne’s material of Fungia apparently 
the very youngest stages were not found, for in Fungia fungites 
the six septa of the first cycle appear before those of the second. 
These young stages I found (1923 a) as buds which developed from
