A NEW GENUS OF FOKAMIiNIFEEA. 453 



specimens now to be described were in like manner found on 

 coral-rock. 



The original block of rock, on which the new foraminiferal 

 type herein described was found, was collected in 1889 by Prof. 

 A. C. Haddon in the Torres Straits, and on this account I propose 

 for it the generic name Haddonia, 



Por the opportunity of, and facilities for, describing the speci- 

 mens I am indebted in the first place to Prof. J. W. Judd, C.B., 

 LL.D., F.R.S., who had previously received the coral-rock for 

 the Greological Collection of the Eoyal College of Science, through 

 Mr. M. F. Woodward of the Biological Laboratory, who had 

 noted it among a collection of corals therein deposited by Prof. 

 Haddon ; and subsequently, by the kindness of Messrs. R. Kirk- 

 patrick and H. M. Bernard, I have been furnished with another 

 specimen from the Haddon Collection, now in the British 

 Museum (Natural History), which has helped to complete our 

 knowledge of the chief characters pertaining to the test of the 

 genus.
