in two cases under different names, without, however, specifying the 

 tyi)es, viz : 



Tetrodon, 194. Tetrodon, 328. 



Leiodo7i, 194. Leisoynus, 328. 



Lagocephahis, 194. Lagocephalus, 328. 



Cirrhisoraus, 194. Cirrhisomus, 328. 



Canthigaster, 194. Psilonotus, 328. 



Dr. Bleeker has preferred to take the first names, but it woukl huve 

 been absolutely impossible to have identified these types with certainty 

 had not some species been enumerated under them, and we may there- 

 fore regard them as determinable only from the last mention of them ; 

 this is fortunate, because the names finally given were much better than 

 those first used. 



Inasmuch as the name Tetrodon was thus restricted to a group of 

 which two Linnwan species are representatives (although Swainson's 

 references did not represent the species), it must be retained for them 

 and their allies, and the subsequently given name Arothron, as well as 

 the still later terms for congeneric species, must be relegated to its syn- 

 onymy. 



The genera Lagocephalus, Liosomus, Cirrhosomtis and Psilonotus may 

 then be retained for the species enumerated under them by Swainson 

 and for related ones.

This subfamily is established for the genus Batrachops of Bibron and 

 Hollard,* founded on a species identified with the '^ Tetr. psittacus JM. 

 Schn., ou Tetr. pcrroqnet do Lacepede." The name Batracliops had 

 been preoccupied for another genus of fishes by Ileckel, and Colomesus 

 is used as a substitute.!
