Etymology: zéya, operculum; dacis, rough, hence more correctly 
written Pomadasys. 
This genus is composed of small shore fishes, some of its representa- 
tives being found in most tropical seas. The three principal types, or 
subgenera, are all represented in American waters. The Pacific coast 
species of this genus are well known, but those of the Atlantic need 
further study and comparison. Several of the species enter fresh 
waters, and perhaps belong to the brackish-water fauna. Numerous 
species are found on the west coast of Africa and about the Cape 
Verde Islands, but so far as known none enter European waters. 
ANALYSIS OF AMERICAN SPECIES OF POMADASIS.
