Dorsal fin typically XIII, 16-19 (rarely 16 or 19), spinous and segmented-ray portions with moderate notch in-between. Anal fin II,18-21 (rarely 18 or 21). Pectoral fin 13-15 (rarely 13, typically 14). Segmented caudal-fin rays 13. Vertebrae 10 or 11 (rarely 10) + 24-26 (rarely

24) = 35-37 (rarely 35). Dentary incisor teeth which includes anterior canine teeth very similar in appearance with incisors, 44-54; posterior dentary canines 0 or 1 (typically 1) on each side. Lateral line lacking pairs of pores, terminating posteriorly at a point between verticals from dorsal-fin spines 8 and 11 (rarely as far anteriorly as 8). With cirrus on posterior rim of anterior nostril; absent on anterior rim. Two color patterns: pale (northern) and dark (southern).
