Snout obtusely pointed and depressed, its preoral leng-tli 2.4 in the length 

 ol tbe head to the first gill-opening; its lateral edges anterior to the nostrils 

 are moderately sharp. Nostrils much nearer the upper lip than the end of the 

 snout, the spac« between them 1.44 in their distance from the tip of the snout; 

 the anterior margin of each has a small lobule projecting backward. Anterior 

 margin of the mouth in advance of that of the eye; the width of the mouth is 

 equal to its distance from the end of the snout, and there is a longer upper 

 and a shorter lower labial fold at each angle. Eye with a nictitating membrane, 

 its diameter about 3 in its distance from the end of the snout; the skin above 

 the eye forms an imperfect fold. Spiracle a small slit and placed about half 

 an eye-diameter behind the eye. Gill-ojienings subequal, the fourth widest and 

 equal to the diameter of tlie eye; the fifth is placed above the base of the 

 pectoral. 



About three series of functional teeth in the upper jaw which are smallest 

 anteriorly and larger laterally. The centre cusp of each lateral tooth is oblique, 

 and there is a sharper angle at its juiu-tion with the ba.sal portion posteriorly 

 than anteriorly; botii the anterior and posterior edges of the base are serrated, 

 but the former less strongly so than .the latter. The teeth of the lower jaw 

 are similar to those of the upper, but are rather less strongly serrated. 



The first dorsal fin is situated midway between the anterior bases of the 

 pectoral and ventral fins; its upper angle is obtusely pointed, and its posterior 

 angle is produced into a sharp point. Tlie second dorsal and anal are small, 

 and subequal in size and shape; the latter commences below the middle of the 

 former. Caudal equal to about one-fifth of the total length. Pectoral obtusely 

 pointed, almost reaching the vertical of the middle of the dorsal when laid back. 



Ciiloiir. — Light grey on the back and sides, lighter below. Fins grey like 

 the body. 



Described and figured from an adult male 1525 mm. long, which was taken 

 by the State Trawlers in New South Wales waters.
