The length of the head is contained four times and a third in the 

 total (without caudal) ; the greatest width of the head is somewhat 

 more than one-half of its length ; the uppei* jaw is longer than the 

 lower. The maxillary barbels extend to the origin of the anal fin, 

 the nasal barbels to the end of the head ; those of the mandil)les are 

 inserted anteriorly at the chin, and rather longer than the head. 

 The eye is situated behind the angle of the mouth, and partly at the 

 lower side of the head ; its diameter is one-third of the length of 

 the head. The dorsal spine is rather slender, obsem-ely serrated be- 

 hind. Caudal fin with the lobes pointed ; the distance between anal 

 and caudal fins is less than the depth of the hinder portion of the 

 tail. Pectoral spine much stronger than that of the dorsal fin, two- 

 thirds as long as the head, extending beyond the dorsal spine, and 

 armed interiorly with strong spines curved backwards. Yentral in- 

 serted below ttie hinder dorsal rays, not half as long as the head. 

 Silvery, with three or four more or less distinct bands, formed by 

 black dots ; a black spot at the base of the caudal.

The length of the head is a little more than the height of the 

 body, and one-fifth of the total (without caudal) ; the greatest wadth 

 of the head is somewhat more than one-half of its length ; the upper 

 profile of the head is scarcely concave, the nape being but httle 

 elevated. The upper jaw is longer than the lower ; the maxiUary 

 barbels extend to the ventrals, those of the nostrils and of the 

 mandible to the end of the head. The occipital process is not 

 covered by skin ; it is slender, and joins the basal bone of the 

 dorsal fin, which is triangular, and half as long as the occipital pro- 

 cess ; a fonticulus along the middle of the upper side of the head, 

 extending to the base of the occipital process. Ej^e large, one-third 

 of the length of the head. The distance between occiput and dorsal 

 fin is nearly equal to that between occiput and snout. Dorsal spine 

 slender, two-thirds of the length of the head, finely serrated 

 behind. The distance between anal and caudal fins is rather less 

 than the depth of the hinder portion of the tail. Pectoral spine 

 much stronger than that of the doreal fin, as long as the head with- 

 out snout, not extending backwards to the vertical from the dorsal
