Leporinus steindachneri Eigenmann, new specific name.

Cliaracidiuni fasciatum Reinhardt.

 Cheirodon interruptus Jenyns. 



A comparison of the specimens recorded by Eigenmann and Ken- 

 nedy" as 6'. inten'-u plus and C. insiyni.s, with a specimen of caJllKruH 

 from Carandasinho, received from the British Museum, shows them 

 to belong- to the same species. It is possible that these are distinct 

 from the C interruj)tns of Jenyns, but we are unable to point out the 

 difi'erences. 

 Cheirodon monodon Cope.

 recorded by Eigenmann'' as Tetragonopterus fasciatus interruptus^ 

 from Rio Grande do Sul, Brazil, seems to belong to this species.
