Disk about twice as broad as long ; tail in the young 1| times 

 the length of the body, but in adults only a little more than half 

 the same length. Body smooth. The horns or cephalic portion 

 of the pectoral fin have a convoluted appearance, and " are used 

 by the animal to draw its prey into its mouth, which opens like a 

 huge cavern between them. The fishermen say they see them 

 swimming slowly along with their mouth open and flapping these 

 great sails inwards, drawing in the smaller Crustacea on which they 

 feed " (Sir W. Elliot, MS.). Teeth small, like flattened, quad- 

 rangular tubercles as broad as wide in adults, twice as broad in 

 the young, with a backwardly directed point ; |^, in a jaw twelve 

 inches across the gape taken from an example upwards of eighteen 

 feet across the disk, and ~ vertical rows opposite the symphysis. 

 In a pair of jaws four inches across, from an example captured at 

 Kurrachee, there are |j. Cantor found in an example thirty inches 

 across the disk ^, and six or seven vertical rows. It may therefore 

 be supposed that the number increases with age, and perhaps alters 

 in shape. The band of teeth reaches nearly to the angle of the 

 mouth. Fins no spine on the tail posterior to the dorsal fin. 

 Colour of a deep purplish superiorly ; white beneath.
