76 TURSIOPS. 
Habitat.—Tasmania ; New South Wales. 
Dimensions.—Total length to eight feet at least. 
References.—Gray, B.M. Catal. Seals and Whales, p. 248, and 
Suppl, p. 69 ; Scott, Seals and Whales, p. 76. 
Jote.—The coloration agrees with that of a herd of large 
Doiphins 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). 
Form stout. Beak short, distinctly marked off from the pre- 
narial adipose elevation by a V-shaped groove. Pectoral fins 
lanceolate ; dorsal fin high and faleate. No lateral grooves on 
the palate. Beak tapering moderately from base toapex. Ptery- 
goid bones united in the median line. Symphysis of lower jaw 
short. Teeth large, numbering from 21 to 25 on each ramus of 
each jaw. 
Vertebre.—C. 7, D. 13, L. 17, Cd. 27, = 64. 
Note.—Gray’s generic name ‘ 7'ursio” (1846) having been used 
by Wagler sixteen years previously for a very distinct Cetacean 
is inadmissable.
