Gunth., Cat. Fishes VIII., p. 401. — (Not macalatiim of Gray, 

 Eichardson, Bleeker, Dumeril, Muller and Henle, and Cantor.) 



Nasal valves confluent, without cirrus, forming together a 

 broad flap in front of the mouth, with the hinder margin concave. 

 Both jaws with a well developed labial fold, extending from the 

 symphysis of the lower jaw, round the angle of the mouth, to the 

 nasal flap. Teeth of the lower jaw of moderate size, with a long 

 median cusp, and a pair of small cusps on each side. Gill- 

 openings narrow. Skin of the trunk rough. Ventral fins 

 obliquely truncated behind. End of the anal fin below the middle 

 of the dorsal, the length of its base is equal to that of the dorsal 

 and three-fourths of its distance from the caudal. Brownish, 

 above and below, with scattered round brown spots scarcely as 

 large as the eye and distant from one another. 



Eort Darwin, Port Jackson. Length two feet.

Dum., Elasmobr., p. 323.— Gunth., Cat. Fishes VIII., p. 404. 



The nasal valves are not confluent, are separated from each 

 other by a very broad interspace, and without prominent cirrus. 

 No labial fold. Teeth very small, tri-cuspid. Head very broad 

 and depressed. End of the anal fin nearly opposite to the end 

 of the dorsal ; anal a little longer than the dorsal, the length of 

 its base being nearly equal to its distance from the caudal. 

 Brownish marbled with darker.

Two dorsal fins without spines, the first behind the ventrals ; 



origin of the anal fin in advance of the second dorsal. Spiracle 



minute, below the posterior angle of the orbit. Nasal and

X
