Body covered with thin, deciduous, cycloid scales. Entire head scaly, 

 with the exception of the angle of the preoperculum, but the scales of the 

 head are deeply embedded in the skin and are covered by minute pores, 

 so that their outlines are almost entirely concealed. Eye large. Mouth 

 moderately large; the upper jaw slightly protractile. Teeth in the pre- 

 maxillary minute, in broad bands, which are separated at the sym- 

 physis ; mandible with a marked concavity in front on each side of the 

 symphysis, this concavity being armed with a band of minute teeth ; 4 

 small canine-like teeth in an irregular group at the symphysis ; .5 addi- 

 tional canines on the mandible, increasing in size backward and con- 

 tinued behind by a short, narrow band of minute teeth ; minute teeth 

 on the vomer in a triangular patch ; palatine teeth in bands, which are 

 broadest in front. Anterior nostril small, circular, not tubular; pos- 

 terior nostril in a long, wedge-shaped slit. Maxillary dilated posteri- 

 orly. Lower lip well developed, broadly attached to the under surface 

 of the maxilla. Preoperculum minutely serrated behind and below ; 

 operculum with 2 thin, flat spines. Branchiostegals 7 ; gill rakers in 

 moderate number, rather stout ; a glandular organ in the upper angle of 

 the gill opening ; fins well developed, the spinous dorsal longer than the 

 second dorsal ; dorsal with 9, anal with 2, spines ; ventrals long ; scales 

 large, thin, cycloid, deciduous; lateral line high up, with a gradual curve 

 nearly following outline of back. This genus resembles Scombrops in 

 form and is closely related to it, but none of the vertical fins is scaly, 

 the tongue is toothless, and the soft dorsal and anal have few rays, (hno, 

 below ; /cAMwv, wave).
