Family CHARACINLDJE. 



Genus Eobrycon Jordan, new genus. 



Eobrycon avus (Woodward). 



(TctragoHopterus avus Woodward, Rev. Mus. Paulista, III, 

 p. 66, 1898, Taubate.) 



Of this species Dr. Branner has received numerous fine speci- 

 mens through Dr. Paulo Pessoa of Rio de Janeiro, from the Ter- 

 tiary Lignite of Taubate, in the Province of Sao Paulo, Brazil.

While this species is doubtless a Characin, and allied to Tetrago- 

 nopterus, its oblong and robust form separates it from that genus, 

 in which the body is very deep and laterally compressed. I sug- 

 gest the generic name of Eobrycon. 



Family CATOSTOMDXF. 



Genus Chasmistes Jordan and Gilbert. 



From a lake deposit in Oregon, near Fossil Lake, and prob- 

 ably of Quaternary Age, Dr. Merriam has obtained a large num- 

 ber of crania of suckers, some of them of large size, probably 

 belonging to the genus Chasmistes now living in the same region.
