248 THE BRIDLED DOLPHIN. 



cue of a very numerous troop, which immediately 

 took to flight on this one being captured. The dark 

 coloured band on the chops of this Dolphin, is the 

 character which induced M. Dussumier to give it 

 the name of Fraenatus. 



DELPHINUS SUPERCILIOSUS, LESSON. 

 PLATE XXVI. 



THE next species we shall adduce of this genus is a 

 very beautiful small variety, for the account of which 

 we are indebted to M. Lesson. 



M. Lesson observed this species after doubling 

 Cape Horn in south latitude 45. M. Garnot 

 when returning to France from Port Jackson, in the 

 Castle-Forbes, subsequently killed one and described 

 it as follows : Its length was four feet two inches. 

 The snout was tolerably long, and distinguished from 

 the forehead by a deep furrow. The dorsal fin was 

 placed somewhat behind the middle of the body, 

 and terminated in an acute point. All the upper 

 parts of the body are of a brilliant blackish-blue 

 colour, and the sides and under part shine with a 

 silvery whiteness. The pectorals are brown, though 

 placed on the white ground of the sides. What 

 especially characterises this Dolphin is a large white 

 streak over the eye, reaching to the front; and 

 another mark like a white ribbon running along the 

 sides of the body near the tail. Teeth . ,.
