The species found on the Florida coast has the body and fins all alike 

 blackish, with violet shades, and is doubtless distinct from H. chloruruSj 

 in which the pectorals and caudal are yellow. Florida to Cuba.

The color in this species, the "Black Grouper" of the Florida coast, 

 is dark gray, freckled with paler, but without distinct spots; fins 'all 

 edged or tipped with black; no yellow nor violet shades anywhere. 

 Caudal lunate. Mouth very large ; the maxillary longer than pectoral. 

 The identification of this species with T. brunneus Poey is very doubtful,

Light brownish violet, covered with close-set round reddish brown 



spots about as large as the pupil, besides large quadrate dark areas on 



the trunk; no red anywhere. Fins dark brown, except the pectorals, 



which are black, with a broad border of bright orange, at least in the 



adult. Maxillary extending beyond orbit. PreoiDercle rounded, finely

The earlier names, Holocentrus punctatus Bloch (Ichth. taf. 241) and 

 Perca maculata Bloch are both preoccupied in this genus.
