Paraneetroplus, Regan, Ann. Mag. Nat. Hist. (7) xvi. 1905, p. 436. 
The single species is apparently allied to Cichlosoma nebuliferum and to Neetroplus 
nematopus. 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.

Fam. 6. SCLAANIDZ. 
The Scianide 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 
features which distinguish them from other Perciform fishes are: (1) the dorsal fin, 
which is either deeply notched or completely divided into two, the anterior spinous
