revealed that the mouth is terminal and directed ventrally when extend- ed. The teeth are villiform and arrayed in a narrow band of three or four poorly differentiated rows. The body depth ranges between 40% and 50% of SL. The length of the second dorsal-fin spine is around 35–40% of body depth, whereas the length of the second anal-fin spine is about 20–30% of body depth. The length of the first dorsal-fin spine is about 12–15% of the second spine. The length of the first anal-fin spine is about 25–30% of the second spine. The dorsal- and anal-fin spines are robust. In lateral view, a weak concavity is present dorsal to the orbit. The caudal fin is deeply forked. The depth of the caudal peduncle is about 5–7% of SL. The lateral line is complete from the opercle to the posterior margin of the caudal peduncle and is parallel with the shape of the back. The lips are somewhat fleshy. The dorsal- and pelvicfin origins are located along the same vertical. The anal-fin origin is located on the vertical from the eighth dorsal-fin spine. There are 16 rakers on the lower limb of the first gill arch. These rakers are about one-quarter to onehalf the length of the gill lamellae. Scales are absent on the chest, head, and nape but present elsewhere on the flanks. The profile of the lower jaw in lateral view is slightly concave. Two postnasal spines are present dorsal to the orbit and posterior to the nasal pores. The supraorbital ridge is serrated.

). There are two narrow, yellow-green stripes on the flank. One stripe straddles the lateral line, and another is near the midline, extending from near the dorsal margin of the opercle to the caudal peduncle. There is a mustardyellow to light-yellow tint to all of the fins, particularly distally. There is more yellow on the edge of the ventral lobe of the caudal fin than there is on the dorsal lobe. There is a distinct black marking on the dorsal-fin membrane between the second and fifth spines. The second through fifth spines are silvery. The nuchal marking is black and triangular or rounded. Light yellow zigzagging lines are present on the dorsal flanks in life, but they rarely extend below the lateral line (

: The body is silvery, with guanine covering most of the body. A slight golden-yellow tint remains in some areas, particularly where scales are intact. The area dorsal to the midline has a lower concentration of guanine than the region ventral to the midline, and the dorsal flank region is devoid of markings. A large, triangular (sometimes rounded) dark-brown marking is present in the nuchal region. The fins are tan, with some remnant silvery coloration retained on the second through fifth spines of the dorsal fin.

), the guanine layer appears quite deep and rich, and the specimens are highly reflective. Specimens without guanine are white to a yellowish off-white color throughout the body, and more yellowish on the head. There is a concentration of melanophores dorsal to the mouth and anterior to the orbit. There are scattered melanophores ventral to the midline, except for a mitten-shaped melanophore-free region posteroventral to the pectoral-fin base.

The dorsal and ventral profiles are about equally convex. The caudal fin is deeply forked. The depth of the caudal peduncle is about 6–7% of SL. The lateral line is complete from the opercle to the posterior margin of the caudal peduncle. The lips are thin and not fleshy. The dorsal- and pelvic-fin origins are located along the same vertical. The anal-fin origin is located on the vertical from the eighth dorsal-fin spine. There are 15–17 rakers on the lower limb of the first gill arch. Scales are present on the chest. The profile of the lower jaw is slightly concave in lateral view. Two robust postnasal spines are present dorsal to the orbit and posterior to the nasal pores. The supraorbital ridge is weakly serrated. (We disagree with Wongratana’s description of this ridge as ‘‘smooth.’’) The body width ranges from about 12% to 16% of SL
