Head depressed; snout shovel-shaped, broadly rounded in front. "Die 

 nasenlocher sind nicht getrennt, an der vorderen und hinteren Klappe ein 

 cirrus." The distance between the nostrils equals the width of the eye; the 

 shortest distance between the nostril and the upper jaw is half as much. A 

 labial fold from the angles of the mouth extends nearly half way to the symphysis. 

 Teeth moderately large, five cusped. Spiracle at the hinder edge of the orbit. 

 Hindmost gill opening above the pectoral. Pectorals broad, length equal that 

 of head without the snout. Middle of ventrals in mid total length, smaller than 

 the anal, base length equal the length of the snout. Dorsal fins small, second 

 somewhat larger than the first. Origin of first dorsal on a vertical from the 

 vent, a little behind the middle of the entire length of body and tail, base ending 

 on a vertical from the origin of the anal. Second dorsal origin behind the middle 

 of the anal, base ending on a vertical from the end of the anal base. Anal broad, 

 origin close behind the ends of the bases of the ventrals, base about equal to length 

 of the head from the snout to the hind border of the orbit. A notch separates 

 the subcaudal from the terminal portion of the caudal; terminal elongate, 

 rounded. Subcaudal deeper forward, without a produced lobe. Scales three 

 cusped. 



Brownish black.
