The scale cover is comparatively uniform. Postpectoral and precaudal scales are elongate, wedge-shaped, elliptical and sometimes carinate; raised median rhombic area of the crown is common; base tending to bulge anteriorly in older scales and an anterior process is common. The pulp cavity is deep and open in young scales, reduced to a slit-like groove in older scales, which leads to a single pulp canal opening being located at the distal end of the scale. Possess specialized branchial denticles.</paragraph>
