GENUS X. SCARUS, Liv. 
Jaws convex, rounded, and furnished with teeth arranged like scales upon 
their edge and upon their anterior surface ; during life, the jaws are covered 
by fleshy lips, but there is no double one adhering to the suborbital. They 
have the oblong form of a Labrus, large scales, and an interrupted Jateral line ; 
three pharyngeal plates, two above and one below, furnished with teeth as in 
the Labrus ; but these teeth are transverse blades, and not rounded like paving- 
stones. 
1. Scarus Abildgaardii, Biocu. 
Back of a beautiful blood-red color, sides paler red ; belly a pale rose-color ; the edge of 
the scales brownish, and the operculum edged with black. Scales large, hexagonal, almost 
smooth ; strie scarcely visible. There is no trunk to the venations of the lateral line, and 
they divide, from the base, into six or seven branches, which give off branches and extend 
over almost the whole scale.
