_ Height of body in length five times. Diameter of orbit in 
_ length of head three and a half times, length of maxillary twice. 
_ Barbel one-third diameter of orbit. Vent in vertical from 
_ twelfth ray of second dorsal, and equidistant from tip of snout 
_ and extremity of second dorsal. Distance of first dorsal from 
_ snout equal to twice the length of mandible. Third ray of 
_ dorsal extremely elongate, extending to the thirty-third ray of 
_ second dorsal and two-thirds of the distance from snout to tip 
_ of caudal, its length more than twice that of the he Anal 
_ inserted immediately behind the vent, at a distance from the 
_ ventrals equal to that of dorsal from snout. Ventral composed 
of three rays,* the first and second much prolonged, the first 
_ almost one-third as long as the body, the second three times as 
_ long as the head, extending to the fortieth ray of the anal fin 
_ and to a point three-fourths of the distance from snout to tip of 
_ caudal; the third shorter than the diameter of the orbit. Pec- 
_ toral four times as long as the operculum. Scales large and 
_ thin, easily wrinkling with the Sida of the thick flabby skin. 
Lateral line much broken on the posterior half of the body. 
Scales in ninety to ninety-one vertical rows and thirty-five 
_ horizontal rows, of which seven are above the lateral line. 
Radial formula: D., 9 or 10, 55 to 57. A. 56, C. 5, 18 to 21, 5.

_ without caudal. The diameter of the orbit is one-fourth of the 
] length of the head, or slightly more. The maxillary extends 
th k skin which envelopes the bases of the 
4q to appear like “a singles ray bifid at the end.”
