Body well compressed, deepest at dorsal origin. Caudal 
peduncle long and slender, least depth about 1/3 its length 
or 3 1/5 in head. Head width 15 to 2 in its length. rather 
obtusely convex, length about = its width. Eye smell, hind 
edge about midway in head length. Mouth inferior, transverse, 
with short gape, each jaw edge as horny plate. Maxillary 
to nostrils, which together near last third in snout. Inter- 
orbital evenly convex. Gill-rekers 5 - 10 short points, Z 
of filaments and latter equal eye. Pseudobranchiae about 
3/5 of filaments. Scales pent. especially along body edges, 
notably breast and belly; apical radii 
10 to 12, though often doubled by incomplete or auxillary 
marginal radii; circuli moderate. Dorsal origin midway be- 
tween snout tip and ceudel base, first branched ray 1¢ in 
head. Anal origin close behind dorsal base, , branched 
ray 1 2/5 to 15 in head. Ceudal well forked, with pointed 
lobes about eye-diameter longer than head and well develonv- 
ed rudimentary caudal rays extending well forward on caudal 
peduncle edges. Pectoral 1 1/10 to 1 1/8 in head or reach
