Gerres peruvianus (p. 39).

POMADASIS (p. 41). 
Pomadasis boucardi (p. 43). 
To the synonymy add :— 
? Pomadasis grandis, Meek, Publ. Columbian Mus., Zool. vii. 1907, p. 116. 
This supposed species is based on a single specimen of 345 mm. from Lake Nicaragua, 
which appears to differ from P. bowcardi, as described, only in characters due to its 
larger size, such as the smaller eye and shorter fin-spines. 
Fam. 10 (a). LUTIANIDH. (To precede the Centropomide, p. 44.) 
Lutianus argentiventris, Peters, 1869 (Neomenis argentiventris, Jord. & Everm. 
Bull. U.S. Nat. Mus. xlvii. 1898, p. 1260), is a marine species from the Pacific coast of 
tropical America. It has been recorded from fresh-water at Caballo Blanco in 
Guatemala by Meek (Publ. Columbian Mus., Zool. vii. 1907, p. 140). | 
CENTROPOMUS (p. 45). 
Centropomus nigrescens (p. 50).

2. Thyrina sardina. 
Melaniris sardina, Meek, Publ. Columbian Mus., Zool. vil. 1907, p. 114, 
Hab. Laxes MANaGua AND NICARAGUA. 
Dr. Meek’s description shows that this species is very closely allied to 7. guatemai- 
ensis of the rivers of the Pacific slope, and they may yet prove to be inseparable. 
FUNDULUS (p. 76). 
Fundulus grandis (p. 79). 
This species is recorded by Barbour and Cole (Bull. Mus. Comp. Zool. 1. 1906, 
p. 156) from near Progreso, Yucatan.
