 Suppl, p. 69 ; Scott, Seals and Whales, p. 76. 



Note. The coloration agrees with that of a herd of large 

 Dolphins seen off Port Stephens by the author, individuals of 

 which while racing the steamer were frequently within less than 

 ten feet of the lookers-on ; one specimen was shot, upon which 

 the whole scattered herd instantly disappeared. 



Genus VI. TURSIOPS, Gervais (1855).

Vertebra. C. 7, D. 13, L. 17, Cd. 27, = 64. 



Note. Gray's generic name " Tursio" (1846) having been used 

 by Wagler sixteen years previously for a very distinct Cetacean 

 is inadmissable.
