teeth biserial, meeting the vomerine ones immediately behind the 

 nasal disk. IMandibular teeth biserial in front, uniserial poste-

 acute ; the nasal and front mandibular ones being stouter and more 

 prominent than the othei's. Dorsal and anal fins ending opposite

The general appearance of this species is like that of hijala. 

 Its lateral line is similar ; but the pectoral is considerably smaller. 

 The vertical fins are low, and taper gradually away. A pale honey- 

 yellow, or faint wood-brown, is the colour of the upper parts, and 

 the belly is lighter. There are no spots. The specimen in the 

 British Museum was brought from China by John Reeves, Esq.,

 11-9 in. To anus, 4-4 in. To gill-openings, 085. Length of 

 pectoral, 0*40 in. Length of gape, 0-35 in. (Fuchardson.)
