 not keeled. Head short, compressed, acute. Occipital keel sharii. 

 Mouth rather large, with small sharp teeth in bands on jaws, tongue,

" The genus Zonichthys Swainson, 1. c, based on this species is characterized by the 

 deep head, its depth at the occiput being greater than its length. {Zovo'^, zone ; ix^vZ,
