Dorsal profile of head slightly elevated in front of anterior nostril, then nearly straight to origin of dorsal fin. Preopercle with two sharp spines at its lower angle. The mouth has several fangs, and a pair of large canines near the tip of the lower jaw which are exposed when the mouth is closed.
