 Paraneetroplus, Regan, Ann. Mag. Nat. Hist. (7) svi. 1905, p. 436. 



The single species is apparently allied to Cichlosoma nehuliferum and to Neetroplus 

 nemafopus. All the teeth are compressed, with pointed or rounded apices.

 from Nicaragua.

The species is evidently closely allied to Cichlosoma nigrofasciatum, but the teeth 

 are compressed and tricuspid, except the median ones of the outer series, which are 

 truncate incisors.

The Sciaenidse are a large family, principally tropical and subtropical shore-fishes ; 

 many of them enter rivers freely and a few are entirely fluviatile. Some of the
