kindly sent me specimens of the attached variety of Deltocyathus italicus, and allowed 
me to figure one of them. 
To all these naturalists I wish to express my obligations and best thanks. My 
thanks are also due to the late Dr F. Briiggemann, who at the time of his death was 
engaged in cataloguing the collection of Corals in the British Museum, and who gave me 
very material assistance.
