Body quite elongate, compressed, its greatest thickness about half 

 its depth; back moderately elevated; dorsal outline convex at nape, 

 gently convex over eyes and snout; head rather low, compressed; 

 caudal peduncle moderately slender, compressed, 3.3 to 3.9 in head; 

 snout rather long, more or less conical, projecting beyond mouth, 3.6 

 to 4.0; eye rather small, 5.2 to 6.9; interorbital 3.7 to 4.2; mouth 

 moderately large, slightly oblique, inferior; lower jaw included; the 

 gape anteriorly well below level of lower margin of eye; lips, maxillary, 

 and chin papillose ; maxillary reaching to or beyond vertical from mid- 

 dle of eye, 2.75 to 3.0 in head; teeth in upper jaw in a rather broad 

 band, with an outer series of rather broadly spaced, somewhat en- 

 larged teeth, though shorter than anterior nostril; band in lower jaw 

 narrower, somewhat enlarged teeth rather irregularly intermixed with 

 smaller ones ; gill rakers short, those at angle scarcely longer than pupil, 

 13 to 15 more or less developed on lower, and 6 to 8 on upper limb of 

 first arch; preopercle with rather fine membranous serrae, those at 

 angle a little enlarged and supported by flat, osseous points; lateral 

 line scarcely arched anteriorly, then curved downward, reaching mid- 

 dle of side above base of anal; scales moderately large, with flexible, 

 ctenoid posterior edges, extending forward nearly to tip of snout, 

 extending only slightly on base of second dorsal, not forming a sheath, 

 present on at least basal half of interradial membranes of caudal, 

 also extending slightly on bases of anal and pectoral, 6 full oblique 

 rows between lateral line and first dorsal spine, and 7 between it 

 and first ray of second dorsal ; dorsal fins close together, the spines 

 slender, the fourth usually longest, not reaching beyond the tip of 

 succeeding spines, 2.2 to 2.9 in head; second dorsal long, with slightly 

 convex margin, highest anteriorly, the highest rays rather notably 

 shorter than the longest spines; caudal lunate, both lobes acute, 

 the upper one slightly the longer; anal with a notably concave
