Length of head 1/4, of caudal 2/9, height of hody nearly 1/4, of dorsal 

 fin 1/6 of the total length. — Byes : diameter 1/4 of length of head, 

 1 diameter from end of snout, and If apart. In large specimens the snout 

 is generally covered with pores. The posterior extremity of the maxilla 

 extends to below the anterior third of the orbit. Third suborbital bone as 

 "wide as the uncovered portion of the cheek below it. Humeral process 

 generally veiy broad, and posteriorly produced in a lancet shaped form, more 

 or less elongated in different specimens. Four short barbels. — Teeth : pharyn- 

 geal, 5, 4, 2/2, 4, 5. — Fins : dorsal much higher than its base is long, it 

 commences midway between the snout and the centre of the caudal fin, and 

 does not extend to over the anal ; caudal forked, lower lobe the longer.— 

 Lateral line : 1\ rows of scales between it and the base of the ventral fin. — 

 Colours : silvery shot with purple ; back of a slaty grey descending in bars 

 towards the lateral line and most distinct in immature specimens. Each scale in 

 adults with a black spot at its base, and two on each forming the lateral line. 

 Fins whitish, tinged with orange. A grey margin to the dorsal and caudal, 

 the lower lobe of which is sometimes stained black. Humeral process black-
