1897.] ON- COEALS FROM THE S.W, PACIFIC OCEAN. 941 



I have conferred on it the name of the Eev. A. E. Eaton, by whom 

 the Algerian species was discovered. 



Eatonia jylumifera, Birula, and E. co pulifera, Cambr., may be 

 thus distinguished : — 



Body slightly broader in front than behind ; nasal prominence 

 furnished with but few spiniform hairs ; rostrum devoid of 

 terminal spine E. plumifcra. 



Body heart-shaped, nmch broadest in front ; nasal prominence 

 furnished with numerous long spiniform hairs of different 

 lengths ; rostrum armed with a long terminal, sharp-pointed, 

 spiny process E. scopulifera.

[Received November 1 , 1897.] 



(Plates LVI. & LVII.) 



The corals described were collected by the author in 1896-7 

 at Punafuti, Eotuma, and Piji, and by Dr. A. Willey at Lifu, 

 Loyalty Islands. I am indebted to Mr. Adam Sedgwick, P.E.S., 

 for entrusting the latter collection to me and for his kindly 

 interest ; my thanks are also due to the authorities of the British 

 Museum for allowing me free access to their types and to the 

 ' Challenger ' specimens. 



The species represented in these collections are 21, viz, 20 Pocil- 

 loj^ora and 1 Seriatopora. Of the former 5 are new, and it has 

 been necessary to redescribe 4 old species. The comparison of 

 the collection with specimens in the British Museum has shown 

 me that several species of Verrill, Dana, and others are not really 

 distinct and must be combined with other species.
