Elongate, compressed posteriorly. Profile before dorsal 

 slightly convex. Snout slightly prominent, obtusely rounded. 

 Height at origin of anal 4 2 / 3 5. Head 4^ 4 3 / 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 ! / 3 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 i ! / 2 i 1 ^ in length of head, strongly 

 serrated behind, less so anteriorly. Adipose fin more than twice 

 as high as long. Anal nearly 3 ! / 2 3 3 /4 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].
