Discussion. 



The President said that the rectification of the name of an old 

 species was of equal importance with the institution of a new form, 

 and congratulated Prof. Eupert Jones on having cleared up an 

 obscure question. 



Dr. Woodward was glad that Prof. Eupert Jones had found some 

 materials previously unrecorded in the Museum collections. The 

 number of specimens exhibited at the new Aluseum was fortunately 

 much larger than formerly in Bloomsbury. 



Prof. Seelet spoke of the importance of determining the forms of 

 rTummulites, and gave a sketch of their distribution in the British 

 Eocene rocks. He also called attention to the variation of the 

 different forms. 



The Author said that the subject of the passage between different 

 so-called species of rTummulites alluded to by Prof. Seeley was very 

 interesting. His own view was that all the forms of jNummulites 

 passed into each other, the whole genus being in fact one very 

 variable species.
