of the jaw with from forty-two to forty-seven 

 slender teeth, arched and pointed ; black above, 

 white underneath ; in length from eight to 

 ten feet. This animal, found in numerous 

 troops in every sea, and celebrated by the ve- 

 locity of its movements, which sometimes cause 

 it to precipitate itself on the helms of vessels, 

 appears to have really been the Dolphin of the 

 ancients. The entire organization of the brain, 

 indicates that degree of docility which they 

 universally attributed to this animal. 



The Dolphin with slender beak {Delph. Rostratus, Shaw.) 



Head more convex, and beak more compressed 

 and slender. Twenty-one, twenty-two, or 

 twenty-three conical teeth at most on each 

 side, and in each jaw. Its tints are paler, 

 which has gained it the appellation of the 

 White Dolphin. It is said to inhabit the Ame- 

 rican Seas. 



The Great Dolphin (Delphinus Tursio.) Vulg. the Whistler. 

 Lacep. XV. f. n. (Bonnaterre.) 



Beak short, wide, and depressed. Twenty-one 

 to twenty-three teeth, altogether conical, and 

 often blunted. Some individuals arrive to more 

 than fifteen feet in length. It would appear 

 that they are to be found in the Mediterranean 

 as well as in the ocean.
