soft rays: 7. Head scales reaching forward to between level of anterior margin of eyes and posterior nostrils. Lower limb of preopercle scaly. Antrorse (forward-directed) suborbital spine present beneath eye. Pelvic fins moderately long, reaching to or almost to level of anus. Color: Upper body greyish-brown, silvery-white below. A pearly-blue streak from behind eye along dorsal fin base. An oblique, brown-edged pearly-blue bar above the pectoral base. An elongate white blotch below lateral line on posterior half of body, a yellowish tinge above this blotch. Snout dusky and a black blotch on opercle.
