Teeth conic, strong, in a narrow band in the front of both jaws, thi!^ 

 narrowing to a single series laterally; outer teeth enlarged in both jaws. 

 Teeth ou vomer in a single series ; palatines smooth. A single slender ten- 

 tacle above orbits, and 1 on each side of nape. Body with moderate 

 cycloid scales ; lateral line high in front, declining behind pectoral fins, 

 not strongly developed, evident on a few scales near head, the remainder 

 of its course traceable by occasional pores on bases of scales or by their 

 notched margins. Dorsal beginning on the nape, its anterior f composed 

 of slender ilexiblo spines, the remainder of soft rays, unbranched; anal 

 without spines; caudal distinct, rounded; ventrals well developed, I, 3. 

 Eyes as in Anableps, the cornea divided by an oblique pigmented baud
