of the body and one fourth more than that of tlie head; least depth of caudal 
peduncle a little less than its length and 3-5 in the dei)th of the l)ody. Upper 
profile of head and nape evenly rounded, with a scarcely perceptible emargina- 
tion above the posterior half of the eye. The occiput and nape moderately 
keeled; head a little longer than deep, 3-05 in the length of the body. Snout 
blunt, with gently rounded profile, its length 2-5 in that of the head; nostrils 
small and approximate, the ])osterior horizontally the anterior vertically oval, 
the latter valvular, its distance from the eye 2*5 in that from the tip of the 
snout. Eye moderate, its diameter 34 m the length of the head and 1-33 in 
that of the snout; interorbital region convex, its width a little less than the eye- 
diameter and 3*6 in the length of the head. Upper jaw slightly the longer; 
maxillary extending to below tlie antm'ior border of the eye, its length 3 in 
that of the head. Depth of preorbilal 145 in the eye-diameter, which is 1*3 
in the depth of the cheek. Angle of preopercle broadly rounded and feebly 
denticulate, the hinder liml) more strongly, evenly, and closely armed, the 
lower entire ; opercle with a short, stout, concealed spine ; post-temporal serrated. 
Scale formula 14/fg/26; 1.1. tubes 55. ^^lany of the scales on the 
tail, especially those near the lateral line, provided with several squamuijE. 
Head, except the snout in front of the nostrils, the lips, and the mandibles 
scaly, the opercular scales largest; three pair of open pores on the lower jaw 
interiorly. Spinous dorsal Avith a low scaly sheath ; soft dorsal and anal with 
a broad basal scaly band and the rays scaly nearly to the tip. 
Dorsal fin xii 20, origiuatijig above the latter lialf of the opercle; spinous 
dorsal with rounded outline; spines moderate, tlie first UO in the second and 
2-3 in the fourth aii<l longest, which is 2*25 in the length of the head and but 
little longer than the adjacent spines; 1 hence it decreases gindixally to the 
last, which is a little shorter than the penultimate and 1-25 in the fourth: 
soft dorsal a little longer than the spinous, with gently rounded outline, the 
middle rays longest, scarcely longer than the fourth spine. Caudal emar- 
ginate, the middle rays 1-33 in the upi)er lobe, whi('h is 3*85 in the body- 
length. Anal iii 7, originating below the eighth dorsal ray, the second spine 
stronger and slightly longer than the third, 245 in the length of the head and 
14 in the second and longest ray, which considerably exceeds the height of 
the soft dorsal. Pectoral short and pointed, extending to below the penulti- 
mate dorsal spine, its length 1-5 in that of the head. Ventral pointed, longer 
than the pectoral, 1*33 in the length of the bead ; outer ray longest, reaching 
the vent. 
Gill-rakers short and stout, 12+20, the longest 4 in the eye-diameter, 
and about one third of the longest fringes. Vent five sevenths of an eye- 
diameter in advance of the anal fin.
