 minent, considerably longer thai}, the eye, the diameter of which is 

 one-seventh of the length of the head ; cleft of the mouth wide, the

 the head ; the maxillary extends beyond the vertical from the poste-

 meter of the orbit. The lower eye is slightly in advance of the 

 apper. Fin-rays scaly : the dorsal fin terminates at a distance from 

 the caudal which is equal to one-third of the depth of the free por- 

 tion of the tail ; its longest rays are in the posterior third of the fin, 

 their length being equal to that of the pectoral, and contained twice 

 and a third in that of the head. Caudal fin rounded ; its length is 

 contained five times and a half in the total. Brownish-grey : body

 the head one-fourth. Bony ridge between the orbits narrow ; eyes 

 pf moderate size. Lateral line with a semicircular ciure above the 

 pectoral. The dorsal commences anteriorly to the eyes, and its distance 

 from the caudal is less than' the depth of the free portion of the tail.
