mandibular are not quite so long. Teeth the villiform band in 

 the premaxillaries is six times longer than wide ; obtusely conical 

 in the palate in two pyriform patches, rather longer than broad, each 

 placed well forward, and largest anteriorly where the two slightly 

 converge, the interspace equal to two thirds of the diameter of the 

 eye. Fins the dorsal about as high as the body, its spine as long 

 as the head excluding the snout, anteriorly its upper half is serrated, 

 its lower roughened, the whole is serrated posteriorly : the length 

 of the base of the adipose dorsal nearly equals that of the rayed 

 fin. Pectoral spine rather shorter than the dorsal, externally 

 serrated in its anterior, rough in its posterior half, internally ib is 

 denticulated, it reaches three fourths of the distance to the ventral. 

 The ventral just reaches the anal. Colour bluish along the back, 

 becoming lighter on the sides and beneath ; dorsal, pectoral, and 

 ventral with a slight tinge of grey. No black mark upon the 

 adipose dorsal.

Head broad, depressed. Eyes small, in front half of the head. 

 Teeth on palate, globular. Barbels the maxillary reach to the 

 middle of pectoral fin. Fins caudal sublunate. Colour head 

 and back bluish leaden ; belly, throat, and hinder part of the tail 

 a dull white. The whole trunk strewed with small, obscure, dusky 

 dots. Dorsal, ventral, and anal with blackish margins. Pectoral 

 and caudal glossy with a faint yellowish tinge. 



This fish has been placed by Cuvier and Valenciennes amongst 

 those having no teeth in the palate, in consequence of their having 

 misunderstood Eussell's description.

 Length of head 4 to 4, of caudal fin 6^, height of body 5| in

 of the head. The median longitudinal groove is wide between the 

 eyes, becomes pointed both anteriorly and posteriorly, and does not
