Characinid^e. 
This is the second family treated of in the fifth volume of 
Dr. Giinther^s Catalogue of Fishes. It is adopted with the same 
limits which were assigned to it by Muller and Troschel. The 
number of generic and specific forms, however, has been much 
increased since the time of the publication of the ^ Horae Ich- 
thyologicae,^^ especially through the labours of Valenciennes and 
Kner. Dr. Gunther has also been able to make numerous 
additions to the knowledge of this family, as will be seen from 
the following systematic synopsis : —
