 Mugil brasiliensis Spix. 



Sel. Gen. Spec. Pise. Rrasil, 1S29, p. 72. Oceano Atlantico. (Museo 

 Monacensi.) 



Head 4; depth 4^; D. IV-I, S; A. Ill, 8; scales 33 in lateral series 

 to base of caudal; snout 4 in head; eye 4^; interorbital space 2^. 

 Mandibular angle obtuse. Ciliiform teeth in l^oth jaws. Scales large, 

 those on caudal peduncle and below soft florsal but little smaller than 

 others on middle of side. Soft dorsal and anal with small scales on 

 basal portions of membranes of anterior rays. Soft dorsal inserted a 

 little behind origin of anal. Pectoral falling short of origin of spinous 

 dorsal by about ^ its own length. Length 8f inches. Rio Janeiro,

Mugil cephalus Linnaeus.

 individual variation.
