Head moderately wide and comparatively firm, slightly longer that 1/2 length to vent. Snout low, not broad, slightly longer than or as long as orbit; width at frontal margin of orbit much narrower than twice preocular length. Orbit large. Mouth terminal and lateral, slightly oblique. Teeth minute, rather conical in shape, set in broad band on premaxillary and in narrow band on dentary. Scales small, cycloid, thin, and deciduous. Mandibular ramus with double scale rows, one of which consisting of large scales and the other smaller ones (Ref. 54421).
