Body oblong, not elevated, comparatively slender and compressed ; head 

 moderate, more or less pointed, but the jaws not notably produced; teeth 

 in the jaws in several series, the outermost very strong; the teeth unequal, 

 couical and pointed; no posterior canines. Cheeks with small scales; 

 operclea with large ones; interopercles naked; preopercle with the verti- 

 cal limb finely serrated. Branchiostegals 5. Gill membranes considerably 

 united, free from the isthmus; gill rakers short. Scales moderate, 35 to 50 

 in the lateral line; lateral line continuous, abruptly bent opi^osite pos- 

 terior part of second dorsal; dorsal long and low, the sjjinous portion 

 much longer than the soft, of 18 or 19 low, subequal, rather strong spines; 

 soft dorsal slightly elevated; anal fin similar to soft dorsal, with 3 strong- 

 graduated spines; caudal truncate; pectorals short, the ventrals inserted 

 behind their axils. Species 2, both American — Tantogolabrits brandtionit< 

 from Brazil, and the following. This genus is very close to the European 

 genus Ctenolabriis, differing in the less perfect scjuamation of the head and 

 in the greater number of dorsal spines and vertebras {Tautoga: Labrua, 

 related genera, from the Latin labrum, lip).
