The western Atlantic species of Umbrina are reviewed. Three species are recognized, two of which, U. coroides and U. broussonnetii, had previously been synonymized. The genus is found in littoral waters having a mud or sand bottom, and its normal range extends from
northern Florida to Argentina, excluding all but the extreme western Gulf of Mexico. Synonymies, descriptions, and illustrations are included, as well as a key to the three species. Due to a lack of information, it was impossible to determine completely the relationships of the western Atlantic
species to those from other areas.
