set, in rather narrow bands ; the lower jaw ’without canines ; upper 
jaw with two long canines, one of which is sometimes obsolete; lateral 
teeth of lower jaw larger than anterior. Preopercle with its mem- 
l)ranaceons edge serrulate, the bone entire. Lower pharyngeal bones 
separate, their teeth all i)ointed. Gill-rakers strong, rather long. Yer- 
tebriie about 14+10 (instead of 10+14 as in Sciccnoids generally). 
Pseudobranehim well developed. Dorsal spines slender ; anal spines 1 
or 2, very feeble ; second dorsal long and low; caudal fin subtruncate or 
lunate. Large fishes chiefly of the waters of America, closely related to 
the Old World genus OtoUthus, from which they are distinguished by the 
absence of canines in the lower jaw. All of them rank high as food- 
fishes ; the flesh is rich, but tender and easily torn ; hence the popular 
name of Weak-fishes. {/.uiov, dog; (t/.cov, Scimua; the modern Greek
