lateral line to base of caudal; 7 scales between base of first dorsal 
spine and lateral line in a vertical series; 14 scales in a vertical 
series between origin of anal and lateral line; snout 37% in head; 
eye 4; maxillary 31%; interorbital space 3%, all these measured 
from tip of upper jaw; fourth dorsal spine 224; eighth dorsal 
ray 2; third anal spine 2%; fifth anal ray 2; upper caudal lobe 
1%; least depth of peduncle 2%; pectoral 14%; ventral 1*/,. 
Body deep, well compressed, comparatively short, and back ele- 
vated. Upper anterior profile steep, forming a very obtuse angle 
above and behind eye. Lower profile less convex than upper. 
Caudal peduncle deep, compressed. Snout short, obtusely convex. 
Eye circular, well anterior. Mouth small, a little oblique, and 
mandible projecting. Maxillary reaching front of eye, without 
supplemental bone, and its distal expansion about equal to diam- 
eter of pupil. Width of preorbital about 24 of orbit. Lips 
fleshy. Teeth in jaws in bands, rather conspicuous. Vomerine 
teeth smaller. Nostrils together, near front of eye. Interor- 
bital space broad, somewhat flattened medianly, otherwise con- 
vex. Opercular flap rounded, not produced, and a little smaller 
than pupil. Gill-rakers 3 + 9 short weak denticles. Pharyngeal 
bones broad, concave and paved with bluntly rounded teeth. 
Scales rather large, reduced on predorsal region, along bases of 
vertical fins and on base of caudal. Scales on chest large, but 
smaller than those on side of body. Scales on cheek in 4 series. 
Tubes in lateral line simple. Lateral line more or less concurrent 
with dorsal profile. Origin of spinous dorsal begins a little be- 
hind that of pectoral, spines graduated from fourth, which 1s 
longest, though last longer than penultimate, and margin of fin
