Length' of head from 4 in the young to 5| in the adult, of ; 

 caudal fin 8, height of body 7 5 in the total length. Eyes minute, 

 situated in the middle of the length of the, head : the width of the 

 interorbital space equals half the length of the snout, or the distance 

 between the eye and the front nostril. Head depressed, as broad 

 as long, and obtusely rounded. Mouth inferior : lips thick, and 

 studded with small tubercular elevations ; the upper and lower 

 lips continuous at the angle of the mouth, but the transverse fold 

 across the lower jaw is interrupted in the middle. Nostrils close 

 together, the anterior round and patent, the posterior tubular ; a 

 barbel divides the two nostrils. Barbels the nasal reach the hind 

 edge of the eye ; the maxillary have broad basal attachments, and 

 reach the root of the pectoral. Of the mandibular barbels the 

 anterior are situated just behind the inner end of the lower labial 

 fold ; they are shorter than the outer pair, which latter extend to 

 the gill-opening. Gill-opening situated on the side of the head in 

 front of and above the base of the pectoral fin. Teetli several 

 rows of pointed ones in each jaw, of which the outer are slightly 

 the larger, rather wide apart, and with rather obtuse summits.

the dorsal arises midway between the snout and the com- 

 mencement of the adipose fin ; its greatest height is one third 

 more than the length of its base; its spine is rudimentary and 

 enveloped in skin. Adipose dorsal very long and low, posteriorly 

 in some instances it is free, in others it almost appears to decrease 

 in 1 height and join the free portion of the tail. Pectoral nearly as 

 long as the head, having the outer half horizontal and the innet 

 vertical ; the spine rudimentary, with a broad, striated, cutaneous
