Dorsal fin XII,13-14 (typically 13), deeply notched between spinous- and segmented-ray sides. Anal fin II,14-16 (typically 15). Vertebrae 10 + 21-22 (typically 22). Dentary incisor teeth 41 to 50 (rarely more than 47; includes anterior canine teeth, very similar in appearance to incisors); posterior canines one on each side. Lateral line lacking vertical pairs of pores, terminating posteriorly at point between vertical from interspace between bases of 10th and 11th dorsal-fin spines and vertical at base of 12th dorsal-fin spine (usually ending at or anterior to base of 11th spine). With short cirrus on posterior rim of anterior nostril, absent on anterior rim. With an intensely dark banded pattern on the body with occasional spot-like intensifications of pigment within the bands; with a large, dark spot on the pectoral-fin base and in the axil. |
