In Dr. Giinther's Catalogue of the Fishes in the liritish .Museum, 

 (vol 8 p 270, 1870) iu the subfamily Tetrodontina (Nvliich incluilcs the 

 TetroLitida' and JHodontida) a genus is admitted with the loUow- 



iug data 



2. Xeuopterus.

The data thus given are quite misleading, but in almost every year 

 since 1870 there has been some reference to the genus in <,uestmu n. 

 which they have been assumed to be correct. In an important me^ 

 ,noir by Dr. Viuciguerra on the Fishes of Burma, just published, and 

 even by Dr. Jordait, Xenopterus has been used instead of ^; ;"'-•''- ;>;. 

 CkoneHnuos. In fact, the only one who has accepted either h. o 

 the name except its inventor has been myselt- The reasons wh.N I 



we used that name rather than Xenopterus I will now .^-e for s«^ 

 are called for in view of the fact that for over twenty years a false light 

 has been followed without any other discovering the truth.
