The height of the body is contained once and three-fifths in the 

 total length (without caudal), the length of the head three times. 

 Scales none ; body with scattered, conical, bony tubercles ; those on 

 the head are much smaller but more numerous, particularly between 

 the orbits and behind the tipper eye ; interorbital space flattish, its 

 width being equal to the vertical diameter of the orbit ; no scales on 

 the fins. Lateral line with a semicircular cui-ve above the pectoral. 

 Lower jaw prominent ; the length of the maxillary is two-fifths of 

 that of the head. The lower eye is slightly in advance of the upper. 

 The dorsal fin terminates close by the root of the caudal ; its longest 

 rays are a little behind the middle of the fin, nearly one-half of the 

 length of the head, and longer than the pectoral. No spine before 

 the anal ; gill-rakers rather widely set, not quite so long as the eye, 

 lanceolate. Greyish or brownish, sometimes spotted with darker.
