Form somewhat like that of Orectolobus; the body elongate and depressed 

 anteriorly, subcylindrical posteriorly. Head broad; snout short, broad, blunt. 

 Nostrils near the end of the snout, with nasoral grooves, and long, slender cirri. 

 Mouth medium, transverse, with labial folds on both jaws, around the angles, 

 and with a symphyseal fold. No transgeneial fold. Teeth small tricuspid. 

 Eyes small. Spiracles medium, behind and partly below the eye. Gill openings 

 small, hindmost widest, hindmost two closer together, three above the pectoral. 

 Pectorals short, broad. Dorsals subequal; first dorsal above or behind the 

 ventrals, second in front of the anal. Anal small, near the subcaudal. Caudal 

 axis raised but slightly. Scales small, keeled.

Body moderate; head broad, depressed; snout short, broadly rounded in 

 front; caudal region longer than the body cavity. Nostrils inferior, nearer 

 to end of snout than to mouth; anterior narial valves reaching the mouth, each 

 with an elongate cirrus; posterior valves with a fold on outer side of nostril 

 and continued in a fold on the outer side of the nasoral groove with free end at 

 angle of the mouth. Mouth medium, with long labial folds, on both jaws, 

 around the angles, not meeting behind the symphysis on the chin. No trans- 

 geneial fold, a short longitudinal groove at the symphysis. Teeth small, tri- 

 cuspid, median cusp largest, several series in function. Eye small. Spiracle 

 smaller than the eye, behind and below the posterior portion, with raised bor- 

 der. Gill openings small, third to fifth above the pectoral, fourth and fifth
