766 DR. A. GUNTHER ON INDIAN FISHES. [Dec. 5. 



discovered by Mr. Day, and shall defer further observations until I 

 have had an opportunity of examining this document. 



With regard to Mr. Day's observations regarding the value of some 

 genera adopted in the 'Catalogue of Fishes,' but questioned by him, 

 I must decline to enter into controversy with him. It is very natural 

 that an author who has to work out the entire field of ichthyology 

 should be guided in this respect by different considerations and hold 

 different views from one who limits himself to a fauna ; and as long 

 as Mr. Day introduces into his papers statements of the kind men- 

 tioned above, I feel that, for the future, it will be undesirable to em- 

 ploy my time in taking notice of similar communications to the 

 Society.
