Reference. — Macleay, Des. Cat. Aust. Fish, vol. 2, p. 316. 



Mr. Macleay has very properly separated this as a distinct 

 species ; as it is easily distinguished from the M* Nieuhqfi by its 

 more obtuse pectorals, less width of disc, and the much greater 

 number of median teeth in a space equal to their width (only 3 or 

 3^ in M. Nieuhofi), more rounded and much shorter muzzle, as 

 well as by the spotted instead of striped disposition of the blue 

 color. 



The only specimen I have seen of this species I obtained many 

 years ago at QueensclifF, and presented to the National Museum, 

 no other example having since occurred. 



This handsome Eagle-ray has not been figured before.
