Rostrum far inferior, relatively short and pointed, 10-12% of OL. Antirostrum and excisura minute. Dorsal rim with broad, rounded, pronounced mediodorsal bulge, anteriorly steeply inclined, posteriorly inclined with long depressed or concave section. Ventral rim rather shallow, regularly curved, with 7-9 medium strong denticles. Posterior rim curved, slightly projecting behind termination of cauda, its tip centrally or inframedian.</paragraph>

Ostial colliculum distinctly longer than caudal colliculum (OCL:CCL = 1.5-1.7) but only slightly wider (OCH:CCH = 1.2-1.4). Caudal pseudocolliculum distinct, about as long as caudal colliculum. Ventral furrow indistinct, sometimes not discernable, relatively close to ventral rim of otolith; dorsal depression small, ventrally marked by short crista superior. Outer face moderately convex throughout without distinct umbo, with distinct excisural furrow and few other weak and short radial furrows.</paragraph>
