 longer, upper protractile. Teeth conical, hooked, in bands, outer series 

 larger ; pharyngeal with a shoulder, median swollen and molar-like. Eye 

 large, as long as snout, one fourth of the head, two thirds to three fifths of 

 the interorbital space. Dorsal origin near tho middle of the total length, a
