Elongate, compressed posteriorly. Profile before dorsal 
slightly convex. Snout slightly prominent, obtusely rounded. 
Height at origin of anal 4?/,—5. Head 4'/,—4*/,, more or 
less granulated above. Occipital process more than twice as 
long as wide at its base. Eye 4—6, rather inferior, partly 
below level of corner of mouth, 2'/,—4 in the interorbital 
space, shorter than snout. Maxillary barbels reach the base 
of the pectorals, the mandibulary barbels reach to the eye 
or to the operculum. Soft dorsal twice or more than twice 
as high as long, its spine 1'/,—1'/, in length of head, strongly 
serrated behind, less so anteriorly. Adipose fin more than twice 
as high as long. Anal nearly 3'/,—3%/, in length. Pectoral 
spine rather stronger than the dorsal one, equal to it or 
longer or shorter. Ventrals shorter than pectorals. Caudal 
deeply forked. Villiform teeth in rounded bands in the jaws, 
teeth on the palate in 4 distinct patches, the two vomerine 
patches may be confluent with each other or, according to 
Day, with the palatine patches. When in full grown specimens 
the vomerine teeth are confluent, they form an oblong, qua- 
drangular patch, which is more than twice as broad as long. 
Silvery, back dark bluish. Fins hyaline, often more or less 
dusky. Length over 1200 mm. [Not seen by us].
